To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

In order to facilitate a better understanding of the embodiments of the present application, the panels related to the present application are described.

With the continuous evolution of antenna packaging technology, multiple antenna elements can be nested with the chip to form an antenna panel or antenna array block (panel), which makes it possible to configure multiple low-correlation panels on the transmitter. Through the beamforming technology of multiple antennas, the energy of the transmitted signal is concentrated in a certain direction for transmission, which can effectively improve the coverage and thus improve the performance of communication. Multiple panels can independently form transmission beams, so that a terminal transmitter can send data streams on multiple panels at the same time through different beams to improve the transmission capacity or reliability.

The terminal device needs to inform the network side of the number of antenna panels configured in the capability report. At the same time, the terminal device may also need to inform the network side whether it has the ability to transmit signals on multiple antenna panels simultaneously. Since the channel conditions corresponding to different panels are different, different panels need to adopt different transmission parameters according to their respective channel information. In order to obtain these transmission parameters, different sounding reference signal (SRS) resources need to be configured for different panels to obtain uplink channel information. For example, in order to perform uplink beam management, an SRS resource set can be configured for each panel, so that each panel performs beam management separately and determines an independent analog beam. In order to obtain the precoding information used for the transmission of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), an SRS resource set can also be configured for each panel to obtain the transmission parameters such as the beam, precoding vector, number of transmission layers, etc. used by the physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmitted on the panel. At the same time, multi-panel transmission can also be applied to PUCCH, that is, the information carried by the same PUCCH resource or the PUCCH resource on the same time domain resource can be sent to the network side through different panels at the same time.

In order to determine the panel used for transmitting signals, the terminal can receive multiple reference signal resource sets configured by the network device, and different reference signal resource sets use different panels to send or receive reference signals. For example, the network device can configure multiple channel state information reference signal (CSI-RS) resource sets, and different sets are received on different panels; or, the network device can configure multiple reference signal sets, and different sets are sent on different panels; or, the network device can indicate multiple physical cell identifiers (PCIs), and the synchronization signal blocks (SSBs) associated with each PCI are used as a set, so that different sets are received on different panels. At this time, each uplink signal can be associated with a reference signal set, or be configured with a reference signal indication information (such as a transmission configuration indication (TCI) state or an SRS resource indication (SRS resource indicator, SRI) information) to indicate a signal in a reference signal set, so that the sending or receiving panel of the associated reference signal set is used as the sending panel of the uplink signal. Alternatively, the network device may configure a panel identification (Identity, ID) for each uplink signal, and determine the transmission panel of the uplink signal according to the panel ID. Therefore, uplink signals transmitted on different panels can be called uplink signals associated with different reference signal resource sets, or uplink signals associated with different panel IDs. At this time, uplink signals associated with the same reference signal resource set, or uplink signals associated with the same panel ID, are all transmitted using the same panel.

It should be noted that SSB can also be called synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH block).

In order to better understand the embodiments of the present application, the uplink incoherent transmission related to the present application is explained.

In the NR system, uplink non-coherent transmission based on multiple transmission reception points (TRP) is introduced. Among them, the backhaul connection between TRPs can be ideal or non-ideal. In an ideal backhaul, TRPs can quickly and dynamically exchange information. In a non-ideal backhaul, TRPs can only quasi-statically exchange information due to large delays. Different TRPs can also independently schedule PUSCH transmissions of the same terminal. Different PUSCH transmissions can be configured with independent transmission parameters, such as beams, precoding matrices, number of layers, etc. The scheduled PUSCH transmissions can be transmitted in the same time slot or in different time slots. If a terminal is scheduled to transmit multiple PUSCHs at the same time in the same time slot, it is necessary to determine how to transmit according to its own capabilities. If the terminal is configured with multiple panels and supports simultaneous transmission of PUSCH on multiple panels, these multiple PUSCHs can be transmitted simultaneously, and the PUSCHs transmitted on different panels are aligned with the corresponding TRPs for analog shaping, thereby distinguishing different PUSCHs through the spatial domain and providing uplink spectrum efficiency (as shown in a in Figure 2). If the terminal has only a single panel or does not support simultaneous transmission of multiple panels, PUSCH can only be transmitted on one panel.

PUSCH transmitted by different TRPs can be scheduled based on multiple downlink control information (Downlink Control Information, DCI), and these DCIs can be carried by different control resource sets (Control Resource Set, CORESET). Specifically, the network side configures multiple CORESET groups, and each TRP is scheduled using the CORESET in its own CORESET group, that is, different TRPs can be distinguished by the CORESET group. For example, the network device can configure a CORESET group index for each CORESET, and different indexes correspond to different TRPs. PUSCH transmitted to different TRPs can also be scheduled based on a single DCI. At this time, the DCI needs to indicate the beams and demodulation reference signal (Demodulation Reference Signal, DMRS) ports and other parameters used by the PUSCH transmitted to different TRPs (as shown in Figure 2 b). In this way, different transmission layers of PUSCH are transmitted on different panels using independent transmission parameters (such as beams, precoding matrices, power control parameters, etc.), but the modulation and coding scheme (Modulation and Coding Scheme, MCS) and physical resources are the same.

It should be noted that FIG. 2 shows a PUSCH transmission based on multiple panels. Specifically, a in FIG. 2 is based on multiple DCIs, and b in FIG. 2 is based on a single DCI.

In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

If the sum of the transmit powers on multiple carriers of a terminal device exceeds the maximum transmit power supported by the terminal device, the terminal device will allocate power in a certain priority order, such as giving priority to carriers with higher signal priorities, thereby ensuring that the total transmit power does not exceed the maximum transmit power supported by the terminal. If the terminal device is configured with multiple panels, and the transmit powers of the multiple panels are independently controlled, the terminal device needs to perform power control between multiple carriers on each panel and between multiple panels to ensure that the power sum on multiple carriers and the power sum on multiple panels do not exceed the corresponding maximum power limit, and at the same time ensure that the power sum of all panels does not exceed the maximum transmit power supported by the terminal device. How to perform power control in these two dimensions (i.e., carrier and panel) while ensuring uplink transmission performance is a problem that needs to be solved.

Based on the above problems, the present application proposes a power allocation scheme that can effectively allocate power between carriers and panels, thereby ensuring the uplink transmission performance of multiple carriers on multiple panels under the premise that the transmission power meets the carrier and panel limitations.

To facilitate a better understanding of the embodiments of the present application, some terms in the embodiments of the present application are explained below.

The maximum transmit power supported by Panel P on carrier C, or the maximum transmit power supported by Panel P on carrier C, specifically refers to the maximum transmit power supported by the terminal device on Panel P and carrier C, denoted as P _c,p,max , as shown in FIG3 .

The maximum transmission power supported by Panel P specifically refers to the maximum total transmission power that the terminal device can support on all carriers of Panel P, which is denoted as P _p,max , as shown in FIG3 .

The maximum transmission power supported by carrier C specifically refers to the maximum total transmission power that all panels of the terminal device can support on carrier C, which is denoted as P _c,max , as shown in FIG3 .

The maximum transmit power supported by the terminal device specifically refers to the maximum transmit power that all panels of the terminal device can support on all carriers, that is, the transmit power corresponding to the power class of the terminal device, denoted as P _UE,max , as shown in FIG3 .

The technical solution of the present application is described in detail below through specific embodiments.

FIG. 4 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 4 , the wireless communication method 200 may include at least part of the following contents:

S210, the terminal device determines a first transmission power of each antenna panel in a plurality of antenna panels on each carrier in at least one carrier;

S220, the terminal device performs power allocation of each antenna panel on the at least one carrier according to the first transmission power of each antenna panel on each carrier, to obtain a second transmission power of each antenna panel on each carrier;

S230, the terminal device allocates power of the multiple antenna panels to each carrier of the at least one carrier according to the second transmission power of each antenna panel on each carrier.

In an embodiment of the present application, the terminal device first performs power allocation on at least one carrier for each of the multiple antenna panels, and then performs power allocation on multiple antenna panels for each of the at least one carrier. That is, in an embodiment of the present application, the power allocation on the antenna panel and the power allocation on the carrier can be performed independently, or the power allocation of multiple carriers can be considered in the power allocation process of the antenna panel, so that the power allocation between carriers and panels can be effectively performed, and the uplink transmission performance of multiple carriers on multiple panels can be guaranteed under the premise that the transmission power meets the carrier and panel restrictions.

In the embodiment of the present application, one antenna panel may have one or more carriers. For example, the terminal device has two panels, one panel is configured with multiple carriers, and the other panel only supports one carrier. For another example, both panels are configured with multiple carriers, and the number of carriers on the two panels can be the same or different. That is, the number of carriers on different panels can be the same or different.

In the embodiments of the present application, the "antenna panel" may also be referred to as an "antenna array block", which is not limited in the present application.

In some embodiments, the at least one carrier may be part or all of the carriers on the corresponding antenna panel. Preferably, the at least one carrier is all the carriers currently activated on the corresponding antenna panel. For example, in the above S210, the terminal device determines the first transmission power of the j-th antenna panel on each carrier in at least one carrier, j is a positive integer, and 1≤j≤the number of the multiple antenna panels; wherein the at least one carrier is all the carriers currently activated on the j-th antenna panel.

In some embodiments, in the above S210, the terminal device calculates the expected transmission power of the uplink signal according to the power control parameter of the uplink signal associated with the jth antenna panel on the i-th carrier; and the terminal device determines the expected transmission power as the first transmission power of the jth antenna panel on the i-th carrier; wherein i and j are both positive integers, and 1≤j≤the number of the multiple antenna panels. By analogy, the first transmission power of the jth antenna panel on each carrier can be determined, and then the first transmission power of each antenna panel on each carrier can be determined.

In some embodiments, the uplink signal is an uplink signal associated with an identification (ID) of the j-th antenna panel, or the uplink signal is an uplink signal associated with a reference signal set of the j-th antenna panel.

For example, on carrier 1, the terminal device needs to transmit two uplink signals, where the panel ID associated with the first uplink signal is 0, and the panel ID associated with the second uplink signal is 1, then the first uplink signal is the uplink signal associated with Panel 0, and the second uplink signal is the uplink signal associated with Panel 1. The terminal device calculates the transmission power of the first uplink signal according to the power control parameter of the first uplink signal, which is the transmission power of the terminal device on carrier 1 of panel 0; the terminal device calculates the transmission power of the second uplink signal according to the power control parameter of the second uplink signal, which is the transmission power of the terminal device on carrier 1 of panel 1.

It should be noted that, based on the first transmission power on each carrier of each panel, there may be the following three situations where the power threshold is exceeded, and corresponding power allocation needs to be performed for these three situations:

The sum of the transmit power of multiple carriers of a panel exceeds the maximum transmit power of the panel;

The sum of the transmit power of multiple panels on one carrier exceeds the maximum transmit power of the carrier;

The total transmit power of multiple panels exceeds the maximum transmit power of the terminal device.

In some embodiments, example 1, the above S220 may specifically include:

When the sum of the first transmission powers of the jth antenna panel on the at least one carrier exceeds the maximum transmission power supported by the jth antenna panel, the terminal device allocates power to the at least one carrier in sequence according to the first priority order of the signals on the carriers, and obtains the second transmission power of the jth antenna panel on each carrier; wherein the sum of the second transmission powers of the jth antenna panel on the at least one carrier does not exceed the maximum transmission power supported by the jth antenna panel; wherein j is a positive integer, and 1≤j≤the number of the multiple antenna panels.

Specifically, in Example 1, if only one carrier is configured on the jth antenna panel, it is only necessary to determine whether the transmission power of the jth antenna panel on the carrier exceeds the maximum transmission power supported by the jth antenna panel.

That is to say, in Example 1, for the j-th antenna panel, under the premise that the sum of the transmit powers of at least one carrier exceeds the maximum transmit power supported on the j-th antenna panel, power is preferentially allocated to the carriers where higher priority signals are located, and then to the carriers where lower priority signals are located. The lower priority signals need to be transmitted at reduced power until the sum of the transmit powers of at least one carrier reaches (not exceeding) the maximum transmit power supported on the j-th antenna panel.

In some embodiments, if the sum of the first transmit powers of at least one carrier on the jth antenna panel does not exceed the maximum transmit power supported on the jth antenna panel, the terminal device can directly use the first transmit power on each carrier of each antenna panel as the second transmit power.

In some embodiments, example 2, the above S220 may specifically include:

In the case that the sum of the first transmission powers of the jth antenna panel on the at least one carrier exceeds the actual transmission power of the jth antenna panel, the terminal device allocates power of the at least one carrier in sequence according to the first priority order of the signals on the carriers, and obtains the second transmission power of the jth antenna panel on each carrier; wherein the sum of the second transmission powers of the jth antenna panel on the at least one carrier does not exceed the actual transmission power of the jth antenna panel; wherein j is a positive integer, and 1≤j≤the number of the multiple antenna panels.

That is to say, in Example 2, if the transmit power on a certain panel is reduced because the total transmit power on multiple panels exceeds the maximum transmit power supported by the terminal device, it is necessary to ensure that the total transmit power of at least one carrier does not exceed the actual transmit power of the panel after the reduction. At this time, the multi-carrier power allocation on the panel should be performed in the first priority order to achieve this goal. If the transmit power on a panel is not reduced, the power allocation does not need to be performed, and it is only necessary to determine whether it exceeds the maximum transmit power supported by the panel (i.e., Example 1).

Specifically, in Example 2, if only one carrier is configured on the jth antenna panel, it is only necessary to determine whether the transmission power of the jth antenna panel on the carrier exceeds the actual transmission power of the jth antenna panel.

In some embodiments, example 3, the above S220 may specifically include:

When the sum of the first transmission powers of the jth antenna panel on the at least one carrier exceeds the maximum transmission power supported by the jth antenna panel, the terminal device preferentially allocates the power on the jth antenna panel to the carrier among the at least one carrier that meets the first condition, and the terminal device distributes the remaining power on the jth antenna panel to other carriers among the at least one carrier that do not meet the first condition in sequence according to the first priority order of the signals on the carriers; wherein the first condition is that the sum of the transmission powers of all antenna panels of the terminal device on one carrier does not exceed the maximum transmission power supported on the carrier, j is a positive integer, and 1≤j≤the number of the multiple antenna panels.

That is to say, in Example 3, if the sum of the first transmission powers of at least one carrier on the jth antenna panel exceeds the maximum transmission power supported on the jth antenna panel, the power is preferentially allocated to the carrier that meets the first condition, and then to the carrier that does not meet the first condition, wherein the carrier that meets the first condition is that the sum of the transmission powers of all antenna panels of the terminal device on the carrier does not exceed the maximum transmission power supported on the carrier. Optionally, if there are multiple carriers that meet the first condition, power allocation is performed in sequence according to the first priority order of the signals on the carriers. Optionally, if there are multiple carriers that do not meet the first condition, power allocation can also be performed in sequence according to the first priority order of the signals on the carriers.

Specifically, in Example 3, power is preferentially allocated to carriers whose total power on the carrier does not exceed the maximum transmit power supported on the carrier. If there is remaining power within the range of the maximum transmit power supported on the jth antenna panel, power is then allocated to carriers whose total power on the carrier exceeds the maximum transmit power supported on the carrier. In other words, if the total power on a panel exceeds the maximum transmit power supported by the panel, the transmit power of carriers with lower priority among the carriers whose power on the carrier exceeds the maximum power that the carrier can support is first reduced, thereby ensuring that the maximum transmit power is not exceeded in both the panel and carrier dimensions. That is, if the sum of the power of a carrier on a panel in both the panel and carrier dimensions exceeds the maximum transmit power, the transmit power will be reduced preferentially.

In Example 3, for example, assume that the transmit powers of the terminal device on carriers 1/2/3 of panel 1 are P _1,1 , P _2,1 , and P _3,1 , respectively, and the transmit powers on carriers 1/2/3 of panel 2 are P _1,2 , P _2,2 , and P _3,2 , respectively, and only carrier 1 satisfies the first condition, i.e., P _1,1 +P _1,2 <P _1,max , P _2,1 +P _2,2 >P _2,max , P _3,1 +P _3,2 >P _3,max , where P _1,max , P _2,max , P _3,max are the maximum transmit powers supported on the three carriers. If the sum of the powers of the three carriers on panel 1 exceeds the maximum transmit power P _c,1,max supported by panel 1, that is, P _1,1 +P _2,1 +P _3,1 >P _c,1,max , the terminal device will first allocate power P _1,1 to carrier 1, and then allocate the remaining power (P _c,1,max -P _1,1 ) to carrier 2 and carrier 3. Assuming that the priority of carrier 2 is higher than that of carrier 3, the terminal device will first allocate power P _2,1 to carrier 2, and then allocate the remaining power (P _c,1,max -P _1,1 -P _2,1 ) to carrier 3. In other words, only the power of carrier 3, which does not meet condition 1 and has the lowest priority, needs to be reduced. Therefore, the total transmit power of the three carriers is P _c,1,max .

In some embodiments, example 4, the above S220 may specifically include:

When the sum of the first transmission powers of the jth antenna panel on the at least one carrier exceeds the actual transmission power of the jth antenna panel, the terminal device preferentially allocates the power on the jth antenna panel to the carrier among the at least one carrier that meets the first condition, and the terminal device distributes the remaining power on the jth antenna panel to other carriers among the at least one carrier that do not meet the first condition in sequence according to the first priority order of the signals on the carriers; wherein the first condition is that the sum of the transmission powers of all antenna panels of the terminal device on one carrier does not exceed the maximum transmission power supported on the carrier, j is a positive integer, and 1≤j≤the number of the multiple antenna panels.

Specifically, in Example 4, if the sum of the first transmit power of at least one carrier on the jth antenna panel exceeds the actual transmit power on the jth antenna panel, the power is preferentially distributed to the carriers that meet the first condition, and then to the carriers that do not meet the first condition, so that the sum of the first transmit power of at least one carrier on the jth antenna panel does not exceed the actual transmit power on the jth antenna panel.

That is to say, in Example 4, if the transmit power on a certain antenna panel is reduced because the total transmit power on multiple antenna panels exceeds the maximum transmit power supported by the terminal device, it is necessary to ensure that the total transmit power of the at least one carrier corresponding to the antenna panel does not exceed the actual transmit power of the antenna panel after the reduction. At this time, the transmit power of some carriers on the antenna panel needs to be reduced. Specifically, the terminal device can first ensure the transmit power of the carrier that meets the first condition, and then distribute the power to other carriers that do not meet the first condition, on the premise that the sum of the transmit power of at least one carrier on the antenna panel does not exceed the actual transmit power on the jth antenna panel. If there are multiple carriers that meet the first condition, power allocation is performed in sequence according to the first priority order; or, if there are multiple carriers that do not meet the first condition, power allocation is performed in sequence according to the first priority order, and the details are not repeated.

Specifically, in Example 4, if only one carrier is configured on the jth antenna panel, it is only necessary to determine whether the transmission power of the jth antenna panel on the carrier exceeds the maximum transmission power supported by the jth antenna panel.

Optionally, in Example 4, if the transmission power on a panel is not reduced, it is not necessary to perform the power allocation, and it is only necessary to determine whether it exceeds the maximum transmission power supported by the panel.

Optionally, in Example 4, if the sum of the first transmission powers of at least one carrier on only one panel exceeds the maximum transmission power supported on the panel, or the sum of the first transmission powers of at least one carrier on only one panel exceeds the actual transmission power on the panel, the power allocation on the panel is performed according to the above method. If multiple panels meet the above conditions, it is necessary to perform multi-carrier power allocation according to the above method respectively. At this time, the terminal device can perform multi-carrier power allocation on each panel in turn according to the order of panel ID, or the order of panels is determined by the terminal implementation.

In some embodiments, when different antenna panels among the multiple antenna panels perform power allocation, whether the same carrier satisfies the first condition needs to be determined separately based on the current transmission power.

For example, after the first panel completes the power allocation of multiple carriers, when the second panel performs power allocation, it is necessary to re-judge whether a carrier meets the first condition based on the second transmission power of the current first panel on each carrier, rather than the first transmission power. For example, when the first panel performs power allocation of multiple carriers, the target carrier does not meet the first condition and its transmission power is reduced, so that the sum of the powers of the two panels on the target carrier does not exceed the maximum power of the target carrier. In this way, when the second panel performs power allocation, the target carrier is a carrier that meets the first condition.

In Example 4, it is assumed that power allocation is performed on panel 1 first and then on panel 2. When power allocation is performed on panel 1, carrier 3 does not meet the first condition (P _3,1 +P _3,2 >P _3,max ), so the transmit power can only be reduced on panel 1. However, when power allocation is performed on panel 2, since the power of carrier 3 on panel 1 is reduced, P' _3,1 +P _3,2 <P _3,max , carrier 3 meets the first condition on panel 2 and power can be allocated preferentially.

In Example 4, when allocating power, the terminal device considers whether the total power on each carrier and the total power on each panel exceed the limit. Through collaborative consideration of the two dimensions (carrier and panel), the signal transmission power is minimized while ensuring that the total power meets the limit. This effectively avoids the problem of excessive power reduction caused by independent power control in the two dimensions, thereby ensuring the performance of uplink transmission.

In Example 4, the terminal device may use the following method to determine the actual transmit power on an antenna panel.

In some embodiments, when the total transmit power on the multiple antenna panels exceeds the maximum transmit power supported by the terminal device, the terminal device reduces the transmit power of at least one of the multiple antenna panels to obtain actual transmit powers on the multiple antenna panels; wherein the sum of the actual transmit powers on the multiple antenna panels does not exceed the maximum transmit power supported by the terminal device.

In some embodiments, when the total transmit power on the multiple antenna panels exceeds the maximum transmit power supported by the terminal device, the terminal device reduces the transmit power on the multiple antenna panels according to a first ratio to obtain actual transmit power on the multiple antenna panels; wherein the sum of the actual transmit power on the multiple antenna panels does not exceed the maximum transmit power supported by the terminal device.

In some embodiments, the first ratio is determined based on a maximum transmit power supported by the terminal device and a total transmit power on each of the multiple antenna panels.

In some embodiments, the first ratio may also be agreed upon by a protocol, or the first ratio may also be configured by a network device.

In some embodiments, the at least one antenna panel includes an antenna panel whose associated control resource set (CORESET) group index is 1, or the at least one antenna panel includes an antenna panel whose antenna panel ID (panel ID) is not 0.

Specifically, if the total transmit power on multiple panels of the terminal device exceeds the maximum transmit power P _UE,max supported by the terminal device, the transmit power on the multiple panels is reduced at the same ratio or the transmit power of at least one of the panels is reduced so that the sum of the actual transmit powers on the multiple panels does not exceed the maximum transmit power supported by the terminal.

For example, the terminal device has two panels, the total transmit power on the first panel is P ₁ , the total transmit power on the second panel is P ₂ , and P ₁ +P ₂ >P _UE,max , then the terminal device can reduce the transmit power of the two panels at the same ratio R = P _UE,max /(P ₁ +P ₂ ), so that the sum of the actual transmit powers of the two panels after the power reduction does not exceed P _UE,max . After the transmit power is reduced, the actual transmit powers of the two panels are P ₁ *P _UE,max /(P ₁ +P ₂ ) and P ₂ *P _UE,max /(P ₁ +P ₂ ), respectively.

For another specific example, the terminal device has two panels, the total transmit power on the first panel is P ₁ , the total transmit power on the second panel is P ₂ , and P ₁ +P ₂ >P _UE,max , the terminal device reduces the transmit power of one of the panels, and the transmit power of the other panel remains unchanged, so that the sum of the powers of the two panels does not exceed the maximum transmit power of the terminal device. For example, the transmit power of the panel with an associated CORESET group index of 1 can be reduced (the panel with an associated CORESET group index of 0 remains unchanged), or the transmit power of the panel with a panel ID other than 0 can be reduced (the panel with a panel ID of 0 remains unchanged).

In one embodiment, if the sum of the first transmit powers of at least one carrier on the jth antenna panel exceeds the maximum transmit power supported on the jth antenna panel, and the total transmit power on multiple antenna panels exceeds the maximum transmit power P _UE,max supported by the terminal device, the terminal device needs to perform power allocation of the at least one carrier in sequence according to the first priority order of the signal carried on the carrier, so that the sum of the first transmit power of at least one carrier on the jth antenna panel does not exceed the maximum transmit power supported on the jth antenna panel, and the total transmit power on multiple antenna panels does not exceed the maximum transmit power supported by the terminal device.

Specifically, if after multi-carrier power allocation is performed on each panel according to the aforementioned method, the total transmit power on multiple panels does not exceed the maximum transmit power supported by the terminal device, there is no need to further reduce the transmit power. If after multi-carrier power allocation is performed on each panel according to the aforementioned method, the total transmit power on multiple panels still exceeds the maximum transmit power supported by the terminal, it is necessary to reduce the transmit power on the multiple panels at the same ratio or reduce the transmit power of at least one of the panels so that the sum of the actual transmit powers on the multiple panels does not exceed the maximum transmit power supported by the terminal device. After the power reduction, the transmit power on each panel can be called the actual transmit power of the panel. At this time, the terminal device needs to further perform power allocation for multiple carriers on each panel in sequence according to the first priority order of the signal carried on the carrier, so that the total transmit power on each panel is reduced to the actual transmit power.

In some embodiments, the above S230 may specifically include:

When the sum of the second transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, the terminal device reduces the transmission power of at least one antenna panel among the multiple antenna panels on the i-th carrier according to a first preset rule, wherein after the power reduction, the sum of the transmission powers of the multiple antenna panels on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, and i is a positive integer.

For example, if the multiple antenna panels transmit different transmission layers of the same PUSCH on the i-th carrier, the terminal device reduces the transmission power of at least one of the multiple antenna panels according to the first preset rule, so that the sum of the second transmission powers of the multiple antenna panels of the terminal device on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier. For example, a DCI can schedule the transmission of PUSCH on the i-th carrier through multiple antenna panels, wherein different transmission layers are transmitted using the same time-frequency resources on the i-th carrier of different antenna panels.

For example, if multiple antenna panels transmit different types of signals or channels on the i-th carrier, or transmit different channels or signals of the same type (for example, two independently scheduled PUSCHs or PUCCHs are transmitted on different antenna panels), the terminal device needs to allocate the power of the multiple antenna panels on the i-th carrier in sequence according to the first priority order of the transmitted signals, so as to ensure that the sum of the second transmission powers of the multiple antenna panels on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier.

In some embodiments, the first preset rule includes at least one of the following:

reducing the lowest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier;

reducing a highest transmission power among second transmission powers of the multiple antenna panels on the i-th carrier;

If a signal transmitted by a first antenna panel among the multiple antenna panels on the i-th carrier includes hybrid automatic repeat request Acknowledgement (HARQ-ACK) information or channel state information (CSI), and a signal transmitted by a second antenna panel among the multiple antenna panels on the i-th carrier does not include the HARQ-ACK information or the CSI, reducing the transmission power of the second antenna panel on the i-th carrier;

reducing the transmission power of the multiple antenna panels on the i-th carrier at the same ratio;

The transmission power of the multiple antenna panels on the i-th carrier is reduced by the same power value.

In some embodiments, the first preset rule at least includes: reducing the lowest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier. For example, the transmission power of the antenna panel with the lowest transmission power among the multiple antenna panels is reduced, that is, the transmission power of the higher antenna panels remains unchanged, thereby ensuring the transmission reliability of at least part of the transmission layer. Furthermore, if the lowest transmission power of the antenna panel reaches a certain threshold value after the power reduction, the transmission power of the antenna panel will no longer be further reduced, but the transmission power of the second lowest antenna panel will be reduced, thereby ensuring that the transmission power of each antenna panel has a minimum value that can support transmission.

In some embodiments, the first preset rule at least includes: reducing the highest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier. For example, the transmission power of the antenna panel with the highest transmission power among the multiple antenna panels is reduced, that is, the transmission power of the lower antenna panels remains unchanged, thereby ensuring that the transmission performance of all transmission layers is equivalent. Furthermore, if the antenna panel with the highest transmission power is reduced to the same as the transmission power of another antenna panel, the terminal device reduces the transmission power of the two antenna panels in the same proportion or at the same power value. For example, after the first transmission power is reduced to the same as the second transmission power, if the transmission power still needs to be reduced, the two transmission powers are reduced at the same time to ensure that the first transmission power will not be lower than the second transmission power after the power reduction, that is, only the current highest transmission power is always reduced.

In some embodiments, the first preset rule includes at least: if the signal transmitted by the first antenna panel among the multiple antenna panels on the i-th carrier includes HARQ-ACK information or CSI, and the signal transmitted by the second antenna panel among the multiple antenna panels on the i-th carrier does not include HARQ-ACK information or CSI, the transmission power of the second antenna panel on the i-th carrier is reduced. For example, if the first panel transmits HARQ-ACK or CSI on the i-th carrier, and the second panel does not transmit HARQ-ACK information and CSI on the i-th carrier, the transmission power of the second panel is reduced. For another example, if the first panel transmits HARQ-ACK information on the i-th carrier, and the second panel does not transmit HARQ-ACK information on the i-th carrier, the transmission power of the second panel is reduced. For another example, if the first panel transmits CSI on the i-th carrier, and the second panel does not transmit HARQ-ACK information and CSI on the i-th carrier, the transmission power of the second panel is reduced.

In some embodiments, the first preset rule at least includes: reducing the transmission power of the multiple antenna panels on the i-th carrier in the same proportion. Assume that the transmission powers of the multiple panels on the i-th carrier are P _c,1 and P _c,2 respectively, and the maximum transmission power supported by the terminal device on the i-th carrier is P _c,max . When (P _c,1 +P _c,2 )>P _c,max , the transmission powers on the two panels obtained after reducing the power on the multiple panels in equal proportion are: P _c,1 *P _c,max /(P _c,1 +P _c,2 ) and P _c,2 *P _c,max /(P _c,1 +P _c,2 ).

In some embodiments, the first preset rule at least includes: reducing the transmission power of the multiple antenna panels on the i-th carrier with the same power value. Specifically, for example, reducing the transmission power corresponding to multiple TCI states with the same power value.

In some embodiments, the above S230 may specifically include:

In a case where the sum of the second transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, the terminal device sequentially allocates power to the multiple antenna panels on the i-th carrier according to the first priority order of the transmitted signals, wherein after the power allocation, the sum of the transmission powers of the multiple antenna panels on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, and i is a positive integer.

In some embodiments, if the transmission power of the third antenna panel among the multiple antenna panels on the i-th carrier is lower than a preset threshold value after power reduction, or if the transmission power of the third antenna panel among the multiple antenna panels on the i-th carrier is lower than a preset threshold value after power allocation, the terminal device does not transmit an uplink signal on the i-th carrier through the third antenna panel. For example, the transmission power of the third antenna panel on the i-th carrier is set to 0.

Specifically, the threshold value is configured by the network device, or the threshold value is reported to the network device by the terminal device through the terminal capability.

Specifically, the threshold value may be an absolute value of the transmit power (eg, X dBm), or the threshold value may be a ratio of the transmit power to a maximum transmit power supported on a carrier (ie, a value between 0 and 1).

In some embodiments, if the sum of the second transmission powers of multiple antenna panels of the terminal device on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, the second transmission power can be directly used as the transmission power of the signal on the i-th carrier.

In some embodiments, the first priority order from high to low is:

Physical Random Access Channel (PRACH);

PUSCH or PUCCH with priority index 1;

PUSCH or PUCCH with priority index 0;

Aperiodic SRS;

Periodic SRS or semi-continuous SRS.

In some embodiments, when the priority indexes of two PUSCHs or PUCCHs are the same, the priority order from high to low is:

PUCCH carrying HARQ-ACK information, or PUCCH carrying Scheduling Request (SR), or PUCCH carrying Link Recovery Request (LRR), or PUSCH carrying HARQ-ACK information;

PUCCH or PUSCH carrying CSI;

PUSCH without HARQ-ACK information and CSI, or PUSCH of type 2 random access procedure.

In an embodiment of the present application, the power allocation on the antenna panel and the power allocation on the carrier are performed independently. If the transmit power is reduced so that the sum of the first transmit powers of at least one carrier on the jth antenna panel is equal to the maximum transmit power supported by the jth antenna panel, then in order to ensure that the sum of the second transmit powers of multiple antenna panels on the ith carrier does not exceed the maximum transmit power supported by the ith carrier, the power of certain antenna panels on certain carriers may be further reduced, so that the sum of the first transmit powers of multiple carriers on the jth antenna panel is less than the maximum transmit power supported by the jth antenna panel. At this time, excessive power adjustment may occur.

Therefore, in the embodiment of the present application, the terminal device first performs power allocation on at least one carrier for each of the multiple antenna panels, and then performs power allocation on multiple antenna panels for each of the at least one carrier. That is, in the embodiment of the present application, the power allocation on the antenna panel and the power allocation on the carrier can be performed independently, or the power allocation of multiple carriers can be considered in the power allocation process of the antenna panel, so that the power allocation between carriers and panels can be effectively performed, and the uplink transmission performance of multiple carriers on multiple panels can be guaranteed under the premise that the transmission power meets the carrier and panel restrictions.

The above text, in conjunction with FIG. 4 , describes in detail a power allocation scheme of the present application. The following text, in conjunction with FIG. 5 , describes in detail another power allocation scheme of the present application. It should be understood that similar descriptions can refer to each other.

FIG. 5 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application. As shown in FIG. 5 , the wireless communication method 300 may include at least part of the following contents:

S310, the terminal device determines a first transmission power of each antenna panel in a plurality of antenna panels on each carrier in at least one carrier;

S320, the terminal device performs power allocation of the multiple antenna panels on each carrier of the at least one carrier according to the first transmission power of each antenna panel on each carrier, to obtain a second transmission power of each antenna panel on each carrier;

S330: The terminal device allocates power of the at least one carrier to each antenna panel in the multiple antenna panels according to the second transmission power of each antenna panel on each carrier.

In an embodiment of the present application, the terminal device first performs power allocation of multiple antenna panels on each carrier of at least one carrier, and then performs power allocation of at least one carrier on each antenna panel of the multiple antenna panels. That is, in an embodiment of the present application, the power allocation on the antenna panel and the power allocation on the carrier can be performed independently, or the power allocation on the panel can be considered simultaneously in the power allocation process of multiple carriers, so that the power allocation between carriers and panels can be effectively performed, and the uplink transmission performance of multiple carriers on multiple panels can be guaranteed under the premise that the transmission power meets the carrier and panel restrictions.

In some embodiments, in the above S310, the terminal device calculates the expected transmission power of the uplink signal according to the power control parameter of the uplink signal associated with the jth antenna panel on the i-th carrier; and the terminal device determines the expected transmission power as the first transmission power of the jth antenna panel on the i-th carrier; wherein i and j are both positive integers, and 1≤j≤the number of the multiple antenna panels. By analogy, the first transmission power of the jth antenna panel on each carrier can be determined, and then the first transmission power of each antenna panel on each carrier can be determined.

In some embodiments, the uplink signal is an uplink signal associated with an identification (ID) of the j antenna panels, or the uplink signal is an uplink signal associated with a reference signal set of the j antenna panels.

It should be noted that, based on the first transmission power on each carrier of each panel, there may be the following three situations where the power threshold is exceeded, and corresponding power allocation needs to be performed for these three situations:

The sum of the transmit power of multiple carriers of a panel exceeds the maximum transmit power of the panel;

The sum of the transmit power of multiple panels on one carrier exceeds the maximum transmit power of the carrier;

The total transmit power of multiple panels exceeds the maximum transmit power of the terminal device.

In some embodiments, the above S320 may specifically include:

When the sum of the first transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, the terminal device reduces the transmission power of at least one antenna panel among the multiple antenna panels according to a first preset rule to obtain a second transmission power of each antenna panel on the i-th carrier; or

When the sum of the first transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, the terminal device sequentially allocates the power of the multiple antenna panels on the i-th carrier according to the first priority order of the transmitted signal to obtain the second transmission power of each antenna panel on the i-th carrier;

The sum of the second transmission powers of the multiple antenna panels on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, i is a positive integer, and 1≤i≤the number of the at least one carrier.

Specifically, if only one panel needs to transmit a signal on the i-th carrier, it is only necessary to determine whether the transmission power of the panel on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier.

In some embodiments, the above S320 may specifically include:

In a case where the sum of the first transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, the terminal device reduces the transmission power of the antenna panels that meet the second condition among the multiple antenna panels on the i-th carrier to obtain the second transmission power of each antenna panel on the i-th carrier; or

When the sum of the first transmission powers of the multiple antenna panels on the i-th carrier exceeds the maximum transmission power supported by the i-th carrier, and the multiple antenna panels all meet or do not meet the second condition, the terminal device reduces the transmission power of at least one antenna panel among the multiple antenna panels according to the first preset rule, or the terminal device sequentially allocates the power of the multiple antenna panels on the i-th carrier according to the first priority order of the transmitted signal to obtain the second transmission power of each antenna panel on the i-th carrier;

The second condition is that the sum of the powers of at least one carrier on an antenna panel exceeds the maximum total transmit power supported by the antenna panel, and the sum of the second transmit powers of the multiple antenna panels on the i-th carrier does not exceed the maximum transmit power supported by the i-th carrier, i is a positive integer, and 1≤i≤the number of the at least one carrier.

In some embodiments, when power is allocated to different carriers in the at least one carrier respectively, whether the same antenna panel satisfies the second condition needs to be determined separately based on the current transmission power.

In some embodiments, the first preset rule includes at least one of the following:

reducing the lowest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier;

reducing a highest transmission power among second transmission powers of the multiple antenna panels on the i-th carrier;

If a signal transmitted by a first antenna panel among the multiple antenna panels on the i-th carrier includes HARQ-ACK information or CSI, and a signal transmitted by a second antenna panel among the multiple antenna panels on the i-th carrier does not include HARQ-ACK information or CSI, reducing the transmission power of the second antenna panel on the i-th carrier;

reducing the transmission power of the multiple antenna panels on the i-th carrier at the same ratio;

The transmission power of the multiple antenna panels on the i-th carrier is reduced by the same power value.

In some embodiments, the first preset rule at least includes: reducing the lowest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier. For example, the transmission power of the antenna panel with the lowest transmission power among the multiple antenna panels is reduced, that is, the transmission power of the higher antenna panels remains unchanged, thereby ensuring the transmission reliability of at least part of the transmission layer. Furthermore, if the lowest transmission power of the antenna panel reaches a certain threshold value after the power reduction, the transmission power of the antenna panel will no longer be further reduced, but the transmission power of the second lowest antenna panel will be reduced, thereby ensuring that the transmission power of each antenna panel has a minimum value that can support transmission.

In some embodiments, the first preset rule at least includes: reducing the highest transmission power among the second transmission powers of the multiple antenna panels on the i-th carrier. For example, the transmission power of the antenna panel with the highest transmission power among the multiple antenna panels is reduced, that is, the transmission power of the lower antenna panels remains unchanged, thereby ensuring that the transmission performance of all transmission layers is equivalent. Furthermore, if the antenna panel with the highest transmission power is reduced to the same as the transmission power of another antenna panel, the terminal device reduces the transmission power of the two antenna panels in the same proportion or at the same power value. For example, after the first transmission power is reduced to the same as the second transmission power, if the transmission power still needs to be reduced, the two transmission powers are reduced at the same time to ensure that the first transmission power will not be lower than the second transmission power after the power reduction, that is, only the current highest transmission power is always reduced.

In some embodiments, the first preset rule includes at least: if the signal transmitted by the first antenna panel among the multiple antenna panels on the i-th carrier includes HARQ-ACK information or CSI, and the signal transmitted by the second antenna panel among the multiple antenna panels on the i-th carrier does not include HARQ-ACK information or CSI, the transmission power of the second antenna panel on the i-th carrier is reduced. For example, if the first panel transmits HARQ-ACK or CSI on the i-th carrier, and the second panel does not transmit HARQ-ACK information and CSI on the i-th carrier, the transmission power of the second panel is reduced. For another example, if the first panel transmits HARQ-ACK information on the i-th carrier, and the second panel does not transmit HARQ-ACK information on the i-th carrier, the transmission power of the second panel is reduced. For another example, if the first panel transmits CSI on the i-th carrier, and the second panel does not transmit HARQ-ACK information and CSI on the i-th carrier, the transmission power of the second panel is reduced.

In some embodiments, the first preset rule at least includes: reducing the transmission power of the multiple antenna panels on the i-th carrier in the same proportion. Assume that the transmission powers of the multiple panels on the i-th carrier are P _c,1 and P _c,2 respectively, and the maximum transmission power supported by the terminal device on the i-th carrier is P _c,max . When (P _c,1 +P _c,2 )>P _c,max , the transmission powers on the two panels obtained after reducing the power on the multiple panels in equal proportion are: P _c,1 *P _c,max /(P _c,1 +P _c,2 ) and P _c,2 *P _c,max /(P _c,1 +P _c,2 ).

In some embodiments, the first preset rule at least includes: reducing the transmission power of the multiple antenna panels on the i-th carrier with the same power value. Specifically, for example, reducing the transmission power corresponding to multiple TCI states with the same power value.

In some embodiments, if the transmission power of the third antenna panel among the multiple antenna panels on the i-th carrier is lower than a preset threshold value after power reduction, or if the transmission power of the third antenna panel among the multiple antenna panels on the i-th carrier is lower than a preset threshold value after power allocation, the terminal device does not transmit an uplink signal on the i-th carrier through the third antenna panel. For example, the transmission power of the third antenna panel on the i-th carrier is set to 0.

Specifically, the threshold value is configured by the network device, or the threshold value is reported to the network device by the terminal device through the terminal capability.

Specifically, the threshold value may be an absolute value of the transmit power (eg, X dBm), or the threshold value may be a ratio of the transmit power to a maximum transmit power supported on a carrier (ie, a value between 0 and 1).

In some embodiments, if the sum of the second transmission powers of multiple antenna panels of the terminal device on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, the second transmission power can be directly used as the transmission power of the signal on the i-th carrier.

In some embodiments, the terminal device allocates power of the multiple antenna panels on each carrier of the at least one carrier according to the first transmission power of each antenna panel on each carrier and in ascending order of carrier index.

In some embodiments, the terminal device allocates power of the multiple antenna panels on each carrier of the at least one carrier in sequence according to the first priority order of the signals on the carriers based on the first transmission power of each antenna panel on each carrier.

In some embodiments, if the sum of the first transmission powers of multiple antenna panels of the terminal device on the i-th carrier does not exceed the maximum transmission power supported by the i-th carrier, the first transmission power on the i-th carrier can be directly used as the second transmission power on the i-th carrier.

In some embodiments, the above S330 may specifically include:

In the case where the sum of the second transmission powers of at least one carrier on the jth antenna panel exceeds the maximum transmission power supported by the jth antenna panel, the terminal device sequentially allocates power to the at least one carrier according to the first priority order of the signals on the carriers; wherein, after the power allocation, the sum of the second transmission powers of the at least one carrier on the jth antenna panel does not exceed the maximum transmission power supported by the jth antenna panel, j is a positive integer, and 1≤j≤the number of the multiple antenna panels; or,

In the case where the sum of the second transmission powers of at least one carrier on the jth antenna panel exceeds the actual transmission power on the jth antenna panel, the terminal device sequentially allocates power to the at least one carrier according to the first priority order of the signal on the carrier; wherein, after the power allocation, the sum of the second transmission powers of the at least one carrier on the jth antenna panel does not exceed the actual transmission power on the jth antenna panel, j is a positive integer, and 1≤j≤the number of the multiple antenna panels. If only one carrier is configured on the jth antenna panel, it is only necessary to determine whether the transmission power of the panel on the carrier exceeds the maximum transmission power supported by the panel or the actual transmission power of the panel.

For specific implementations, please refer to the relevant description in the embodiment corresponding to FIG. 4 above.

In some embodiments, the first priority order from high to low is:

PRACH;

PUSCH or PUCCH with priority index 1;

PUSCH or PUCCH with priority index 0;

Aperiodic sounding reference signal SRS;

Periodic SRS or semi-continuous SRS.

In some embodiments, when the priority indexes of two PUSCHs or PUCCHs are the same, the priority order from high to low is:

PUCCH carrying HARQ-ACK information, or PUCCH carrying SR, or PUCCH carrying LRR, or PUSCH carrying HARQ-ACK information;

PUCCH or PUSCH carrying CSI;

PUSCH without HARQ-ACK information and CSI, or PUSCH of type 2 random access procedure.

Therefore, in the embodiment of the present application, the terminal device first performs power allocation of multiple antenna panels on each carrier in at least one carrier, and then performs power allocation of at least one carrier on each antenna panel in the multiple antenna panels. That is, in the embodiment of the present application, the power allocation on the antenna panel and the power allocation on the carrier can be performed independently, or the power allocation on the panel can be considered simultaneously in the power allocation process of multiple carriers, so that the power allocation between carriers and panels can be effectively performed, and the uplink transmission performance of multiple carriers on multiple panels can be guaranteed under the premise that the transmission power meets the carrier and panel restrictions.

The technical solution of the present application is described in detail below through specific embodiments 1 to 4.

In the first embodiment, the terminal device first distributes power to the antenna panel and then distributes power to the carrier. The power distribution on the antenna panel and the power distribution on the carrier are performed independently. Specifically, the power distribution is performed through S11 to S13.

S11, the terminal device determines a first transmission power on each carrier of each panel.

Specifically, the terminal device calculates the transmission power of the uplink signal on a carrier according to the power control parameter of the uplink signal associated with the target panel, that is, the first transmission power of the target panel on the carrier.

The uplink signal associated with the target panel may be an uplink signal associated with the panel ID of the target panel, or an uplink signal associated with a reference signal set of the target panel.

For example, on carrier 1, the terminal needs to transmit two uplink signals, where the panel ID associated with the first uplink signal is 0, and the panel ID associated with the second uplink signal is 1, then the first uplink signal is the uplink signal associated with Panel 0, and the second uplink signal is the uplink signal associated with Panel 1. The terminal device calculates the transmit power of the first uplink signal according to the power control parameter of the first uplink signal, which is the transmit power of the terminal on carrier 1 of panel 0; the terminal calculates the transmit power of the second uplink signal according to the power control parameter of the second uplink signal, which is the transmit power of the terminal on carrier 1 of panel 1.

Based on the first transmission power of each carrier of each panel, there may be the following three situations where the power threshold is exceeded, and corresponding power allocation needs to be performed for these three situations:

The sum of the transmit power of multiple carriers of a panel exceeds the maximum transmit power of the panel;

The sum of the transmit power of multiple panels on one carrier exceeds the maximum transmit power of the carrier;

The sum of the total transmit power of multiple panels exceeds the maximum transmit power of the terminal.

S12, the terminal device performs power allocation for multiple carriers on each panel respectively, and determines the second transmission power on each carrier of each panel.

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel exceeds the maximum transmission power supported on the target panel, the power of the multiple carriers is allocated in sequence according to the first priority order of the signals carried on the carriers, so that the sum of the first transmission powers of the multiple carriers on the target panel does not exceed the maximum transmission power supported on the target panel.

That is to say, under the premise that the sum of the transmission powers of multiple carriers does not exceed the maximum transmission power supported by the target panel, power is first allocated to the carriers where the signals with higher priority are located, and then to the carriers where the signals with lower priority are located. The signal with the lowest priority needs to be transmitted at a lower power until the sum of the transmission powers of multiple carriers reaches the maximum transmission power supported by the target panel.

In some implementations, the first priority order from high to low is:

PRACH;

PUSCH or PUCCH with priority index 1;

PUSCH or PUCCH with priority index 0;

Aperiodic SRS;

Periodic SRS or semi-continuous SRS.

If two PUSCHs or PUCCHs have the same priority index, the priority order from high to low is:

PUCCH carrying HARQ-ACK information, or PUCCH carrying SR, or PUCCH carrying LRR, or PUSCH carrying HARQ-ACK information;

PUCCH or PUSCH carrying channel state information CSI;

PUSCH without HARQ-ACK information and CSI, or PUSCH of Type 2 random access procedure.

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel does not exceed the maximum transmission power supported by the target panel, the first transmission power on each carrier of each panel may be directly used as the second transmission power.

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel exceeds the actual transmission power on the target panel, the power of the multiple carriers is allocated in sequence according to the first priority order of the signals carried on the carriers, so that the sum of the first transmission powers of multiple carriers on the target panel does not exceed the actual transmission power on the target panel.

That is to say, if the transmit power on a certain panel is reduced because the total transmit power on multiple panels exceeds the maximum transmit power supported by the terminal, it is necessary to perform multi-carrier power allocation on the panel in the first priority order, provided that the total transmit power of multiple carriers does not exceed the actual transmit power of the panel after the reduction. If the transmit power on a panel is not reduced, it is not necessary to perform the power allocation, and it is only necessary to determine whether it exceeds the maximum transmit power supported by the panel.

In one implementation, if the total transmit power on multiple panels of the terminal exceeds the maximum transmit power P _UE,max supported by the terminal, the transmit power on the multiple panels is reduced at the same ratio or the transmit power of at least one of the panels is reduced so that the sum of the actual transmit powers on the multiple panels does not exceed the maximum transmit power supported by the terminal.

For example, the terminal has two panels, the total transmit power on the first panel is P ₁ , the total transmit power on the second panel is P ₂ , and P ₁ +P ₂ >P _UE,max , then the terminal can reduce the transmit power of the two panels at the same ratio R = P _UE,max /(P ₁ +P ₂ ), so that the sum of the actual transmit powers of the two panels after the power reduction does not exceed P _UE,max . After the transmit power reduction, the actual transmit powers of the two panels are P ₁ *P _UE,max /(P ₁ +P ₂ ) and P ₂ *P _UE,max /(P ₁ +P ₂ ), respectively.

In another example, the terminal may also reduce the transmit power of one of the panels and keep the transmit power of the other panel unchanged, so that the sum of the powers of the two panels does not exceed the maximum transmit power of the terminal. For example, the transmit power of the panel with the associated CORESET group index of 1 may be reduced (the panel with the associated CORESET group index of 0 remains unchanged), or the transmit power of the panel with a panel ID other than 0 may be reduced (the panel with a panel ID of 0 remains unchanged).

In one embodiment, if the sum of the first transmit powers of multiple carriers on the target panel exceeds the maximum transmit power supported by the target panel, and the total transmit power on the multiple panels exceeds the maximum transmit power P _UE,max supported by the terminal, the terminal needs to allocate the power of the multiple carriers in sequence according to the first priority order of the signals carried on the carriers, so that the sum of the first transmit powers of the multiple carriers on the target panel does not exceed the maximum transmit power supported by the target panel, and the total transmit power on the multiple panels does not exceed the maximum transmit power supported by the terminal.

If after performing multi-carrier power allocation for each panel according to the aforementioned method, the total transmit power on multiple panels does not exceed the maximum transmit power supported by the terminal, there is no need to further reduce the power.

If after performing multi-carrier power allocation for each panel according to the aforementioned method, the total transmit power on multiple panels still exceeds the maximum transmit power supported by the terminal, it is necessary to reduce the transmit power on the multiple panels or reduce the transmit power of at least one of the panels at the same ratio, so that the sum of the actual transmit powers on the multiple panels does not exceed the maximum transmit power supported by the terminal. After this step, the transmit power on each panel is called the actual transmit power of the panel. At this time, the terminal needs to further perform power allocation for multiple carriers on each panel in sequence according to the first priority order of the signal carried on the carrier, so that the total transmit power on each panel is reduced to the actual transmit power.

S13, the terminal device performs power allocation of multiple panels on each carrier according to the second transmission power on each carrier of each panel.

If the sum of the second transmit powers of multiple panels of the terminal on the target carrier exceeds the maximum transmit power supported by the target carrier, the transmit power of at least one of the multiple panels is reduced according to a first preset rule, or the power of the multiple panels on the target carrier is allocated in sequence according to the first priority order of the transmitted signal, so that the sum of the second transmit powers of multiple panels of the terminal on the target carrier does not exceed the maximum transmit power supported by the target carrier.

Among them, the first priority order refers to the previous description.

The first preset rule includes at least one of the following:

1. The transmission power of the panel with the lowest transmission power among the multiple panels is reduced, that is, the higher transmission power remains unchanged, thereby ensuring the transmission reliability of at least part of the transmission layer. Further, if the lowest transmission power reaches a certain threshold value after the power reduction, the transmission power is no longer reduced, but the second lowest transmission power is reduced, thereby ensuring that the transmission power of each panel has a minimum value that can support transmission.

2. Reduce the transmission power of the panel with the highest transmission power among the multiple panels, that is, the lower transmission power remains unchanged, so as to ensure that the transmission performance of all layers is equivalent. Further, if the panel with the highest transmission power is reduced to the same as the transmission power of another panel, the transmission power of the two panels is reduced by the same proportion or the same power value. For example, after the first transmission power is reduced to the same as the second transmission power, if the transmission power still needs to be reduced, the two transmission powers are reduced at the same time to ensure that the first transmission power will not be lower than the second transmission power after the power reduction, that is, only the current highest transmission power is always reduced.

3. If the first panel transmits HARQ-ACK information or CSI on the target carrier and the second panel does not transmit HARQ-ACK information and CSI on the target carrier, the transmit power of the second panel is reduced. In one embodiment, if the first panel transmits HARQ-ACK information on the target carrier and the second panel does not transmit HARQ-ACK information on the target carrier, the transmit power of the second panel is reduced. In another embodiment, if the first panel transmits CSI on the target carrier and the second panel does not transmit HARQ-ACK information and CSI on the target carrier, the transmit power of the second panel is reduced.

4. Reduce the transmit power of the multiple panels in the same proportion. Specifically, assume that the transmit powers of the multiple panels on the target carrier are P _c,1 and P _c,2 respectively, and the maximum transmit power supported by the terminal on the carrier is P _c,max . In the case where (P _c,1 +P _c,2 )>P _c,max , the transmit powers of the two panels obtained after reducing the powers of the multiple panels in equal proportion are: P _c,1 *P _c,max /(P _c,1 +P _c,2 ) and P _c,2 *P _c,max /(P _c,1 +P _c,2 ).

5. Reduce the transmission power corresponding to the multiple TCI states by the same power value.

In one implementation, if multiple panels transmit different transmission layers of the same PUSCH on a target carrier, the terminal reduces the transmit power of at least one of the multiple panels according to a first preset rule, so that the sum of the second transmit powers of the multiple panels of the terminal on the target carrier does not exceed the maximum transmit power supported by the target carrier. For example, one DCI may schedule the transmission of a PUSCH on multiple panels and target carriers, where different transmission layers are transmitted on target carriers of different panels.

In another embodiment, if the multiple panels transmit different types of signals or channels on the target carrier, or transmit different channels or signals of the same type (for example, two independently scheduled PUSCHs or PUCCHs are transmitted on different panels), the terminal needs to allocate the power of the multiple panels on the target carrier in sequence according to the first priority order of the transmitted signals, on the premise that the sum of the second transmit powers of the multiple panels on the target carrier does not exceed the maximum transmit power supported by the target carrier.

In the above method, if the transmit power of a panel on a carrier is lower than a preset threshold after power allocation or transmit power reduction, no uplink signal is transmitted on the carrier of the panel, that is, the transmit power of the panel on the carrier is set to 0.

Specifically, the threshold value is configured by the network device, or reported to the network device by the terminal through UE capabilities.

Specifically, the threshold value may be an absolute value of the transmit power (eg, X dBm), or a ratio of the transmit power to a maximum transmit power supported on a carrier (ie, a value between 0 and 1).

If the sum of the second transmit powers of multiple panels of the terminal on the target carrier does not exceed the maximum transmit power supported by the target carrier, the second transmit power may be directly used as the transmit power of the signal on the target carrier.

It should be noted that, in this embodiment, the power allocation on the panel and the power allocation on the carrier are performed independently. If the sum of the first transmit powers of multiple carriers on the target panel is equal to the maximum transmit power supported by the target panel by reducing the transmit power in S12, then in order to ensure that the sum of the second transmit powers of multiple panels on the target carrier does not exceed the maximum transmit power supported by the target carrier in S13, the power of some panels on some carriers may be further reduced, so that the sum of the first transmit powers of multiple carriers on the target panel is less than the maximum transmit power supported by the target panel, that is, excessive power reduction may occur.

In Embodiment 2, the terminal device first performs power allocation on the carrier, and then performs power allocation on the antenna panel. The power allocation on the antenna panel and the power allocation on the carrier are performed independently. Specifically, the power allocation is performed through S21 to S23.

S21: The terminal determines a first transmission power on each carrier of each panel.

S22, performing power allocation of multiple panels on each carrier respectively, and determining a second transmission power on each carrier of each panel.

Specifically, if the sum of the first transmission powers of multiple panels of the terminal on the target carrier exceeds the maximum transmission power supported by the target carrier, the transmission power of at least one panel among the multiple panels is reduced according to a first preset rule, or the power of the multiple panels on the target carrier is sequentially allocated according to the first priority order of the transmitted signal, so that the sum of the second transmission powers of the multiple panels of the terminal on the target carrier does not exceed the maximum transmission power supported by the target carrier. The first preset rule and the first priority order refer to the description of Example 1.

If the sum of the first transmission powers of multiple panels of the terminal on the target carrier does not exceed the maximum transmission power supported by the target carrier, the first transmission power on the target carrier can be directly used as the second transmission power on the carrier.

S23: Perform multi-carrier power allocation on each panel according to the second transmission power on each carrier of each panel.

Specifically, if the sum of the second transmission powers of multiple carriers on the target panel exceeds the maximum transmission power supported on the target panel, the power of the multiple carriers is allocated in sequence according to the first priority order of the signal on the carrier, so that the sum of the second transmission powers of the multiple carriers on the target panel does not exceed the maximum transmission power supported on the target panel. In other words, power is preferentially allocated to the carrier where the signal with higher priority is located, and then to the carrier where the signal with lower priority is located, until the sum of the transmission power of multiple carriers reaches the maximum transmission power supported on the target panel. The carrier with lower priority needs to reduce the transmission power or not transmit.

In another implementation, if the sum of the second transmit powers of multiple carriers on the target panel does not exceed the maximum transmit power supported by the target panel, the second transmit power may be directly used as the actual transmit power on each carrier of each panel for signal transmission.

Specifically, if the sum of the second transmission powers of multiple carriers on the target panel exceeds the actual transmission power on the target panel, the power of the multiple carriers is allocated in sequence according to the first priority order of the signals on the carriers so that the sum of the second transmission powers of the multiple carriers on the target panel does not exceed the actual transmission power on the target panel.

That is, power is first allocated to the carrier where the signal with higher priority is located, and then to the carrier where the signal with lower priority is located, until the sum of the transmission power of multiple carriers reaches the actual transmission power on the target panel.

Specifically, the actual transmit power on the target panel can be determined as follows: if the total transmit power on multiple panels of the terminal exceeds the maximum transmit power supported by the terminal, the transmit power on the multiple panels is reduced at the same ratio or the transmit power of at least one of the panels is reduced so that the sum of the actual transmit power on the multiple panels does not exceed the maximum transmit power supported by the terminal. After this step, the transmit power on each panel is the actual transmit power. If the total transmit power on multiple panels of the terminal does not exceed the maximum transmit power supported by the terminal, the actual transmit power on the target panel is equal to the sum of the second transmit powers of multiple carriers on the target panel, that is, no power allocation is required at this time.

In another embodiment, if the sum of the first transmit powers of multiple carriers on the target panel exceeds the maximum transmit power supported on the target panel, and the total transmit power on the multiple panels exceeds the maximum transmit power PUE,max supported by the terminal, the terminal needs to allocate the power of the multiple carriers in sequence according to the first priority order of the signals carried on the carriers, so that the sum of the first transmit powers of the multiple carriers on the target panel does not exceed the maximum transmit power supported on the target panel, and the total transmit power on the multiple panels does not exceed the maximum transmit power supported by the terminal.

Specifically, the first priority order refers to the description of Embodiment 1.

It should be noted that, in this embodiment, the power allocation on the panel and the power allocation on the carrier are performed independently. If in step 2, the sum of the second transmit powers of multiple panels on the target carrier is equal to the maximum transmit power supported by the target carrier by reducing the transmit power, then in step 3, in order to ensure that the sum of the second transmit powers of multiple carriers on the target panel does not exceed the maximum transmit power supported by the target panel, the power of some panels on some carriers may be further reduced, so that the sum of the second transmit powers of multiple panels on the target carrier is less than the maximum transmit power supported by the target carrier, that is, excessive power reduction may occur.

In Embodiment 3, the terminal device first performs power allocation on the antenna panel and then performs power allocation on the carrier. The power allocation on the antenna panel and the power allocation on the carrier are performed jointly. Specifically, the power allocation is performed through S31 to S33.

S31: The terminal determines a first transmission power on each carrier of each panel.

S32: The terminal performs power allocation on multiple carriers on each panel respectively, and determines the second transmission power on each carrier of each panel.

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel exceeds the maximum transmission power supported on the target panel, the power is preferentially allocated to the carriers that meet the first condition, and then to the carriers that do not meet the first condition, wherein the carrier that meets the first condition is that the sum of the transmission powers of all panels of the terminal on the carrier does not exceed the maximum transmission power supported on the carrier. Among them, if there are multiple carriers that meet the first condition, power allocation is performed in sequence according to the first priority order of the signal on the carrier. If there are multiple carriers that do not meet the first condition, power allocation can also be performed in sequence according to the first priority order of the signal on the carrier.

Specifically, power is preferentially allocated to carriers whose total power does not exceed the maximum transmit power supported by the carrier. If there is remaining power within the range of the maximum transmit power supported by the target panel, power is then allocated to carriers whose total power exceeds the maximum transmit power supported by the carrier. In other words, if the total power on a panel exceeds the maximum transmit power supported by the panel, the transmit power of carriers with lower priority among the carriers whose power exceeds the maximum power supported by the carrier is first reduced, thereby ensuring that the maximum transmit power is not exceeded in both the panel and carrier dimensions. That is, if the sum of the power of a carrier on a panel in both the panel and carrier dimensions exceeds the maximum transmit power, the transmit power will be reduced preferentially.

For example, assume that the transmit powers of the terminal on carriers 1/2/3 of panel 1 are P _1,1 , P _2,1 , and P _3,1 , respectively, and the transmit powers on carriers 1/2/3 of panel 2 are P _1,2 , P _2,2 , and P _3,2 , respectively, and only carrier 1 satisfies the first condition, i.e., P _1,1 +P _1,2 <P _1,max , P _2,1 +P _2,2 >P _2,max , P _3,1 +P _3,2 >P _3,max , where P _1,max , P _2,max , and P _3,max are the maximum transmit powers supported on the three carriers. If the sum of the powers of the three carriers on panel 1 exceeds the maximum transmit power P _c,1,max supported by panel 1, that is, P _1,1 +P _2,1 +P _3,1 >P _c,1,max , the terminal first allocates power P _1,1 to carrier 1, and then allocates the remaining power (P _c,1,max -P _1,1 ) to carrier 2 and carrier 3. Assuming that the priority of carrier 2 is higher than that of carrier 3, the terminal first allocates power P _2,1 to carrier 2, and then allocates the remaining power (P _c,1,max -P _1,1 -P _2,1 ) to carrier 3. In other words, only the power of carrier 3, which does not meet condition 1 and has the lowest priority, needs to be reduced. Therefore, the total transmit power of the three carriers is P _c,1,max .

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel does not exceed the maximum transmission power supported by the target panel, the first transmission power on each carrier of each panel may be directly used as the second transmission power.

Specifically, if the sum of the first transmission powers of multiple carriers on the target panel exceeds the actual transmission power on the target panel, the power is preferentially allocated to the carriers that meet the first condition, and then to the carriers that do not meet the first condition, wherein the carrier that meets the first condition is that the sum of the transmission powers of all panels of the terminal on the carrier does not exceed the maximum transmission power supported on the carrier, so that the sum of the first transmission powers of multiple carriers on the target panel does not exceed the actual transmission power on the target panel.

That is to say, if the total transmit power on multiple panels exceeds the maximum transmit power supported by the terminal, resulting in the transmit power on a certain panel being reduced, then the transmit power of some carriers on the panel needs to be reduced accordingly. At this time, the terminal can first ensure the transmit power of the carrier that meets the first condition, and then distribute the power to other carriers that do not meet the first condition on the premise that the sum of the transmit power of multiple carriers on the panel does not exceed the actual transmit power on the target panel. If there are multiple carriers that meet or do not meet the first condition, power allocation is performed in sequence according to the first priority order, and the details are not repeated.

If the transmission power on a panel is not reduced, there is no need to perform the power allocation, and it is only necessary to determine whether it exceeds the maximum transmission power supported by the panel.

If the sum of the first transmission powers of multiple carriers on only one panel exceeds the maximum transmission power supported on the target panel, or the sum of the first transmission powers of multiple carriers on only one panel exceeds the actual transmission power on the target panel, the power allocation on the panel is performed according to the above method. If multiple panels meet the above conditions, it is necessary to perform power allocation of multiple carriers respectively according to the above method.

At this time, the terminal may perform multi-carrier power allocation on each panel in sequence according to the order of panel IDs, or the order of the panels may be determined by the terminal implementation.

It should be noted that whether the same carrier on different panels meets the first condition needs to be judged separately. After the first panel completes the power allocation of multiple carriers, the second panel determines whether a carrier meets the first condition when performing power allocation. It needs to re-judge based on the second transmission power of the current first panel on each carrier, rather than the first transmission power. For example, when the first panel performs power allocation of multiple carriers, the target carrier does not meet the first condition and its transmission power is reduced, so that the sum of the power of the two panels on the target carrier does not exceed the maximum power of the target carrier. In this way, when the second panel performs power allocation, the target carrier is the carrier that meets the first condition.

In the above example, assuming that power allocation is performed on panel 1 first and then on panel 2, when power allocation is performed on panel 1, carrier 3 does not meet the first condition (P _3,1 +P _3,2 >P _3,max ), so the transmit power can only be reduced on panel 1. However, when power allocation is performed on panel 2, since the power of carrier 3 on panel 1 is reduced, P' _3,1 +P _3,2 <P _3,max , carrier 3 meets the first condition on panel 2 and power can be allocated preferentially.

Based on this embodiment, when allocating power, the terminal considers whether the total power on each carrier and the total power on each panel exceed the limit. Through collaborative consideration of the two dimensions, the signal transmission power is minimized while ensuring that the total power meets the limit. This effectively avoids the problem of excessive power reduction caused by independent power control in the two dimensions, thereby ensuring the performance of uplink transmission.

S33: The terminal device allocates power of multiple panels on each carrier to each carrier according to the second transmission power on each carrier of each panel.

If the sum of the second transmission powers of the multiple panels of the terminal on the target carrier exceeds the maximum transmission power supported by the target carrier, the transmission power of at least one panel among the multiple panels is reduced according to the first preset rule, or the power of the multiple panels on the target carrier is sequentially allocated according to the first priority order of the transmitted signal, so that the sum of the second transmission powers of the multiple panels of the terminal on the target carrier does not exceed the maximum transmission power supported by the target carrier. The first preset rule and the first priority order refer to the description in Example 1.

In Embodiment 4, the terminal device first performs power allocation on the carrier, and then performs power allocation on the antenna panel, and the power allocation on the antenna panel and the power allocation on the carrier are performed jointly. Specifically, the power allocation is performed through S41 to S43.

S41, the terminal determines a first transmission power on each carrier of each panel. Please refer to the description in Embodiment 1 for details.

S42: Perform power allocation of multiple panels on each carrier to determine the second transmission power on each carrier of each panel.

If the sum of the first transmission powers of multiple panels of the terminal on the target carrier exceeds the maximum transmission power supported by the target carrier, the transmission power of the panel that meets the second condition on the target carrier is first reduced so that the sum of the second transmission powers of multiple panels of the terminal on the target carrier does not exceed the maximum transmission power supported by the target carrier. The sum of the powers of multiple carriers on the panel that meets the second condition exceeds the maximum total transmission power supported by the panel, and the sum of the powers of multiple carriers on the panel that does not meet the second condition does not exceed the maximum total transmission power supported by the panel.

If multiple panels satisfy the second condition, or multiple panels do not satisfy the second condition, the transmission power of at least one of the multiple panels is reduced according to the first preset rule, or the power of the multiple panels on the target carrier is allocated in sequence according to the first priority order of the transmitted signal.

In specific implementation, if the terminal is configured with multiple carriers, the power of multiple panels on each carrier can be allocated in order from small to large according to the carrier index (serving cell index) or according to the first priority order of the signal on the carrier.

It should be noted that when performing power allocation on different carriers, whether the same panel meets the second condition needs to be judged separately. After the first carrier completes the power allocation of multiple panels on the carrier, the second carrier needs to re-judge whether a panel meets the second condition when performing power allocation based on the second transmission power of the current panel on the first carrier, rather than the first transmission power. For example, when performing power allocation on multiple panels on the first carrier, the first panel meets the second condition and its transmission power is reduced, so that the sum of the transmission powers on multiple carriers of the first panel does not exceed the maximum transmission power of the first panel. In this way, when performing power allocation on the second carrier, the first panel does not meet the second condition.

For example, assume that the transmit powers of the terminal on carriers 1/2/3 of panel 1 are P _1,1 , P _2,1 and P _3,1 respectively, and the transmit powers on carriers 1/2/3 of panel 2 are P _1,2 , P _2,2 and P _3,2 respectively, and panel 1 satisfies the second condition, i.e., P _1,1 +P _2,1 +P _3,1 >P _c,1,max , and panel 2 does not satisfy the second condition, i.e., P _1,2 +P _2,2 +P _3,2 <P _c,2,max , where P _c,1,max and P _c,2,max are the maximum transmit powers supported on panel 1 and panel 2. If the sum of the transmit power of panel 1 and panel 2 on carrier 1 exceeds the maximum transmit power supported by carrier 1 (i.e., P _1,1 +P _1,2 >P _1,max ), and the sum of the transmit power of panel 1 and panel 2 on carrier 2 also exceeds the maximum transmit power supported by carrier 2 (P _2,1 +P _2,2 >P _2,max ), it is necessary to perform multi-panel power allocation on carrier 1 and carrier 2 respectively. Specifically, when performing power allocation on carrier 1, the terminal first reduces the transmit power P _1,1 of panel 1 that meets the second condition on carrier 1, and the transmit power of panel 2 on carrier 1 remains unchanged, so that P' _1,1 +P _1,2 ＝P _1,max after the power reduction. Because the transmit power of panel 1 on carrier 1 is reduced, resulting in P' _1,1 +P _2,1 +P _3,1 <P _c,1,max , when power is allocated on carrier 2, both panel 1 and panel 2 do not meet the second condition and need to reduce power according to the first preset condition.

In addition, if the sum of the first transmission powers of multiple panels of the terminal device on the target carrier does not exceed the maximum transmission power supported by the target carrier, the terminal device can directly use the first transmission power on the target carrier as the second transmission power on the carrier without reducing the power.

Based on this embodiment, when allocating power, the terminal considers whether the total power on each carrier and the total power on each panel exceed the limit. Through collaborative consideration of the two dimensions, the signal transmission power is minimized while ensuring that the total power meets the limit. This effectively avoids the problem of excessive power reduction caused by independent power control in the two dimensions, thereby ensuring the performance of uplink transmission.

S43, the terminal device performs multi-carrier power allocation for each panel according to the second transmission power on each carrier of each panel. For details, refer to the description in Embodiment 2.
