Background technique

The Physical Uplink Sharing Channel (PUSCH) can last multiple time slots or symbols in the time domain for repeated transmissions (Repetitions) in order to improve the reliability of transmission. However, when the terminal has enabled the function of uplink transmission skipping (i.e. UL skipping), when PUSCH performs repeated transmission, if the terminal has no data to transmit, the terminal will not perform repeated transmission of PUSCH; when there is There is a resource conflict between the Physical Uplink Control Channel (PUCCH) and PUSCH. Even if there is no data to be transmitted in the terminal data memory, the terminal still multiplexes the Uplink Control Information (UCI) on the PUSCH. Up to transmission, at this time PUSCH carries padding data.

However, if the terminal determines whether to transmit PUSCH repeated transmission, there is no conflict between PUCCH and PUSCH repeated transmission. At this time, if there is no data transmission that needs to be transmitted in the terminal data memory, the terminal will determine not to perform PUSCH repeated transmission. If there is a conflict between PUCCH and one or more PUSCH retransmission resources during PUSCH retransmission, the terminal cannot multiplex UCI on the conflicting PUSCH retransmission resources, resulting in UCI transmission failure.

It should be noted that in the embodiment of this application, only the NR system is used The base station in is taken as an example, but the specific type of base station is not limited.

To facilitate understanding, some contents involved in the embodiments of this application are described below:

1. UCI defined by the physical layer is multiplexed on PUSCH

UCI is transmitted on PUCCH. If the terminal is transmitting data on PUSCH, in principle, it can send PUCCH and PUSCH at the same time, that is, UCI remains on PUCCH. However, this will increase the cubic metric (Cubic Metric). In addition, if the requirements for out-of-band transmission are to be met at higher transmit power, and the PUSCH and PUCCH are transmitted at the same time with a large interval in the frequency domain, PUCCH is generally transmitted at both ends of the frequency band, which will have a negative impact on the radio frequency (Radio Frequency) ,RF) implementation brings challenges. Therefore, under normal circumstances, if the PUCCH resources carrying UCI overlap with the PUSCH resources in time, the base station will ensure that the UCI multiplexing processing time is met when scheduling the PUSCH, and the UCI will be multiplexed with the data on the PUSCH. Avoid sending PUCCH at the same time, as shown in Figure 2.

2. PUCCH and PUSCH conflict handling

In New Radio (NR) version 15 (Release15, R15), within a PUCCH group (PUCCH group), regardless of whether PUCCH and PUSCH are in the same serving cell or different serving cells, PUCCH and PUSCH are not supported at the same time. transmission, so when the PUCCH time domain resources overlap with the PUSCH time domain resources (including partial overlap and full overlap), the UE will discard it according to the corresponding rules when certain time requirements are met, for example, Scheduling Request (Scheduling Request, SR) PUCCH overlaps with PUSCH that does not carry the Uplink-Sharing Channel (UL-SCH) (i.e., PUSCH without UL-SCH). The UE discards PUSCH and transmits SR PUCCH, or multiplexes UCI onto PUSCH for transmission. For example, Hybrid Automatic Repeat RequestAcknowledge (HARQ-ACK)/Channel State Information (CSI) PUCCH and PUSCH overlap, and the UE multiplexes HARQ-ACK/CSI to PUSCH for transmission. Specifically, the UE first processes conflicts between multiple PUCCHs (if any). The result of the processing is one or more non-overlapping PUCCHs, and then processes conflicts between PUCCH and PUSCH. If the PUCCH overlaps with only one PUSCH, the UCI (excluding SR) is multiplexed on the PUSCH. If the PUCCH overlaps with multiple PUSCHs, the UE selects a PUSCH for multiplexing according to the corresponding rules. The rules for selecting the multiplexed PUSCH can be as follows:

First priority: PUSCH with aperiodic CSI (A-CSI);

Second priority: PUSCH with the earliest starting slot;

Third priority: dynamically scheduled PUSCH > configure authorized PUSCH or semiPersistentOnPUSCH;

The fourth priority: PUSCH with a smaller index of the serving cell > PUSCH with a larger index of the serving cell;

Fifth priority: PUSCH transmitted early > PUSCH transmitted late.

3. Uplink transmission skip function defined by Media Access Control (MAC) layer

The MAC layer defines the process for the terminal to perform uplink transmission skipping (UL skipping). As shown in Figure 3, if the following conditions are met, the MAC entity will not generate a MAC Protocol Data Unit (PDU) for the HARQ entity:

1). The MAC entity is configured with the parameter skipUplinkTxDynamic, and the value of this parameter is set to true (true). The MAC locates the HARQ entity indicated in the uplink grant (UL grant);

2). There is no aperiodic CSI requested for this PUSCH transmission in the UL grant;

3). MAC PDU includes zero MAC Service Data Unit (SDU);

4). The MAC PDU only contains periodic buffer status reports (Buffer Status Report, BSR), and there is no data available for any logical channel group (Logical Channel Group, LCG), or the MAC PDU only contains padding BSR.

4. UCI multiplexing when PUSCH enables uplink transmission skip function

When the uplink transmission skip function is enabled on PUSCH and there is overlap between PUCCH and PUSCH, UCI will be multiplexed on the PUSCH. If the terminal has data to transmit, the MAC will generate a PDU carrying the data. If the terminal has no data to transmit, the MAC will generate a padding PDU. Therefore, regardless of whether the terminal has data to transmit, UCI will multiplex transmission on the PUSCH with the uplink transmission skip function enabled.

5. PUSCH repetitions (Repetitions) transmission in the time domain

PUSCH can last for multiple time slots or symbols in the time domain and perform repeated transmissions in the time domain in order to improve the reliability of transmission. Specifically, a complete data packet can be transmitted on each time slot or symbol, and then repeatedly transmitted on multiple time slots or symbols, and different redundancy version numbers can be used during repeated transmission to improve performance. Among them, the number of time slots or symbols for repeated transmission is defined as the number of repeated transmissions, which can be recorded as K.

In NR Rel-15, the concept of aggregation transmission is introduced for PUSCH/Physical Downlink SharedChannel (PDSCH), that is, for the set of symbols allocated in a single time slot, based on the configured aggregation factor (Aggregation Factor), Recurring in multiple consecutive time slots, that is, the exact same symbol set exists in N consecutive time slots specified by the aggregation factor N, used to carry scheduled PUSCH/PDSCH. The PUSCH/PDSCH transmitted in these multiple time slots are for the same HARQ process. The redundancy version corresponding to the PUSCH/PDSCH transmission in each time slot is based on the predefined value based on the downlink control information (DCI) indication value. value sequence to set. The aggregated transmission of PUSCH is called PUSCH repetition type A (PUSCHrepetition type A) in Ultra-Reliable and Low Latency Communications (URLLC) version 16 (Release16, R16).

Correspondingly, a PUSCH repetition transmission scheme is also introduced in URLLC R16, which is called PUSCH repetition type B (PUSCH repetition type B). In this scheme, a single non-Fallback DCI (can be DCI format 0_1 or DCI format 0_2) can be scheduled by indicating the index of a row in the time domain resource allocation table of the high-level configuration. Determine one or more nominal PUSCHs (Nominal PUSCH) that are continuous in time. The first Nominal PUSCH among these Nominal PUSCHs is determined by the K2 parameter and SLIV in this row. The remaining Nominal PUSCHs are followed one by one. Neighbor arrangement, that is, DCI determines the time domain resource allocation of L*K consecutive symbols (where L is the number of consecutive symbols occupied by each Nominal PUSCH, and K is the number of consecutive Nominal PUSCHs in the time domain). When a certain non-Fallback DCI format is configured to support PUSCH repetition type B, in the time domain resource allocation table configured independently for it, compared to the time domain resource allocation table of NR R15, a new column of numberofrepetitions parameters, resources The numberofrepetitions parameter of each row in the allocation table can be configured independently to indicate the number of Nominal PUSCH corresponding to this row.

6. PDSCH processing time

When the UE receives the scheduled PDSCH, it will indicate the K1 value (slot granularity), which indicates the slot where the PUCCH corresponding to the scheduled PDSCH is located. At the same time, combined with the PRI indication in the DCI, it decodes the physical downlink control channel (Physical DownlinkShared Channel, PDCCH) of the DCI. The specific control channel element (Control Channel Element, CCE) index (index) and the PUCCH transmission size (size) select the PUCCH resource (resource) according to the protocol rules.

At the same time, the time between symbol L where the first symbol of the PUCCH resource is located after adjustment in the tracking area (TA) and the last symbol of the corresponding PDSCH needs to meet the following timeline (timeline) _{Tproc, 1} :

T _{proc, 1} = (N ₁ +d _{1, 1} ) (2048+144)·κ2 ^-μ ·T _c

Among them, N1 is related to whether there is an additional demodulation reference signal (additional DMRS) according to different UE capabilities (capability), as shown in Table 1 and Table 2.

Table 1 PDSCH processing time of PDSCH processing capability 1

Table 2 PDSCH processing time of PDSCH processing capability 1

Correspondingly (Sub-Carrier Spacing (SCS) of the PDCCH that schedules the PDSCH, SCS of the scheduled PDSCH, SCS of the UL channel where the PUCCH for HARQ-ACK transmission is located), different T _proc,1 are calculated respectively, and N1 and SCS corresponding to the maximum T _proc,1 value;

When l ₁ =12, N1,0 =14, in other cases N1,0 =13;

When the UE is configured with multiple component carriers (Component Carrier, CC), the TA needs to consider multiple carriers;

d _1,1 is related to the type, length and number of symbols overlapping with PDCCH.

7. Physical layer PUSCH scheduling time

The time interval between the end symbol of the PDCCH scheduled for PUSCH and the start symbol of PUSCH is at least T _proc,2 =max((N ₂ +d _2,1 )(2048+144)·κ2 ^-μ · _TC ,d _{2, 2} ).

Among them, the corresponding relationship between N2 and μ is shown in Table 3 and Table 4, where Table 3 and Table 4 represent UE processing capabilities 1 and 2 respectively.

If the first symbol of PUSCH is composed of DM-RS only, d _2,1 =0, otherwise d _2,1 =1.

If DCI is scheduled to trigger the switching of a bandwidth part (BWP), d _2,2 is equal to the switching time, otherwise d _2,2 =0.

Table 4 Preparation time of PUSCH timing capability 2

μ PUSCH preparation time N2 [symbol] 0 5 1 5.5 2 Frequency range 1 to 11

8. Physical layer UCI reuse time

When a single slot PUCCH overlaps with a single slot PUCCH or PUSCH, the UE will use the existing multiplexing rules to multiplex all UCI on one PUCCH or PUSCH. If there are multiple PUSCH/PUCCH overlaps, the last symbol of any PDSCH will be The time interval of the starting symbol of the earliest PUCCH/PUSCH among the overlapping PUCCH/PUSCH is is the maximum value of the processing time of all PDSCHs, that is/> The processing time of the i-th PDSCH is:

Among them, d _1,1 is related to DMRS configuration, PDCCH and PDSCH configuration.

Similarly, the time interval from the last symbol of any PDCCH to the starting symbol of the earliest PUCCH/PUSCH in the overlapping PUCCH/PUSCH is is the maximum value of the processing time of all PUSCH, that is The processing time of the i-th PUSCH is:

9. Processing time N3

NR R15 introduces a scheduling and HARQ time limit, namely N3. Its definition is as follows:

If the UE receives the first PDCCH, it indicates that the UE feeds back HARQ-ACK on the first PUCCH of a certain slot. If the UE receives the second PDCCH after the first PDCCH, it also indicates that the UE feeds back HARQ-ACK on the slot, and the HARQ-ACK is fed back. The PUCCH resource is the second PUCCH, then the interval from the end symbol position of the second PDCCH to the start symbol position of the first PUCCH must be greater than or equal to N ₃ ·(2048+144)·κ·2 ^-μ · _TC , N3 is related to the subcarrier spacing and UE capability. If the serving cell where the second PDCCH is located and all the serving cells of the PUCCH where HARQ-ACK is multiplexed in the slot are configured with PDSCH processing capability 2, the value of N3 is N ₃ =3 corresponds to μ=0, N ₃ =4.5 corresponds to μ=1, N ₃ =9 corresponds to μ=2, that is, the UE takes the value of N1 according to the PDSCH processing capability 2; otherwise, the value of N3 is N ₃ =8 corresponding to μ=0 , N ₃ =10 corresponds to μ=1, N ₃ =17 corresponds to μ=2, and N ₃ =20 corresponds to μ=3, that is, the value of N1 is based on the PDSCH processing capability of 1.

The information transmission method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios. It should be noted that the information transmission method provided in this embodiment can be applied to, but is not limited to, a scenario where the terminal enables the uplink transmission skipping (UL skipping) function of PUSCH and PUSCH performs repeated transmissions.

Please refer to Figure 4. Figure 4 is a flow chart of an information transmission method provided by an embodiment of the present application. The method can be executed by a terminal. As shown in Figure 4, it includes the following steps:

Step 401. In the case that the first UCI is transmitted on the first PUSCH transmission opportunity, or the reception time of the downlink control signaling scheduled for the second UCI meets the preset conditions, if the PUCCH carrying the second UCI and the second PUSCH are transmitted If there is a conflict between opportunities, the second UCI is sent on the second PUSCH transmission opportunity;

Wherein, the first PUSCH transmission opportunity is an initial transmission opportunity of PUSCH repeated transmission, and the second PUSCH transmission opportunity is a retransmission opportunity of the PUSCH repeated transmission.

In this embodiment, the above-mentioned first UCI may be a dynamically scheduled or semi-statically configured UCI. For example, the above-mentioned first UCI may be HARQ-ACK, CSI or SR, etc. The above-mentioned second UCI may also be a dynamically scheduled or semi-statically configured UCI. For example, the above-mentioned second UCI may also be HARQ-ACK, CSI or SR, etc. It should be noted that the second UCI may be any UCI, and the number of the second UCI may be one or more.

The above-mentioned first PUSCH transmission opportunity is the initial transmission opportunity of the above-mentioned PUSCH repeated transmission, that is, the above-mentioned first PUSCH transmission opportunity is used for the initial transmission of the transport block. For example, for dynamically scheduled PUSCH repeated transmission, the first PUSCH repeated transmission corresponds to The transmission opportunity is used for the initial transmission of the transmission block, that is, the transmission opportunity corresponding to the first PUSCH repeated transmission is the first PUSCH transmission opportunity. For semi-statically configured PUSCH repeated transmission, the corresponding redundancy version (Redundancy Version, RV) is 0 The transmission opportunity corresponding to the PUSCH repeated transmission is used for the initial transmission of the transport block, that is, the transmission opportunity corresponding to the PUSCH repeated transmission with an RV of 0 is the first PUSCH transmission opportunity.

The above-mentioned second PUSCH transmission opportunity is a retransmission opportunity for PUSCH repeated transmission, that is, the above-mentioned second PUSCH transmission opportunity is used for retransmission of a transport block. The above-mentioned PUSCH repeated transmission may also be called transport block (Transport Block, TB) repeated transmission. The second PUSCH transmission opportunity may be any PUSCH transmission opportunity used for transport block retransmission, and the number of the second PUSCH transmission opportunities may be one or more.

The above-mentioned PUSCH may be a dynamically scheduled PUSCH, such as a dynamic grant PUSCH (Dynamic Grant PUSCH, DG PUSCH), or may be a semi-statically configured PUSCH, such as a configured grant PUSCH (Configured Grant PUSCH, CG PUSCH).

It should be noted that the PUSCH transmission opportunity involved in this embodiment can also be described as PUSCH transmission opportunity, PUSCH transmission or PUSCH repetition, etc. For example, the above-mentioned existence of the first UCI being transmitted on the first PUSCH transmission opportunity can also be described as the existence of the first UCI being transmitted on the first PUSCH transmission opportunity, or the existence of the first UCI being transmitted on the first PUSCH transmission opportunity, or it can be described as There is a first UCI transmitted on the first PUSCH repetition, etc.

The above-mentioned conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity can be understood to mean that the PUCCH carrying the second UCI and the second PUSCH transmission opportunity overlap in the time domain.

In one embodiment, in the case where the first UCI is transmitted on the first PUSCH transmission opportunity, the terminal is allowed to have a resource conflict between the PUCCH that is scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity, that is, in In the case where the first UCI is transmitted on the first PUSCH transmission opportunity, the network device may schedule or configure a resource conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity. Specifically, in the case where the first UCI is transmitted on the first PUSCH transmission opportunity, if there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may send the second PUSCH transmission opportunity on the second PUSCH transmission opportunity. UCI, that is, the second UCI is multiplexed on the second PUSCH transmission opportunity. It should be noted that the terminal can send all or part of the information of the second UCI on the second PUSCH transmission opportunity.

For example, as shown in Figure 5, PUSCH occasion#1 is used for the initial transmission of TB, PUSCH occasion#2, PUSCHoccasion#3 and PUSCH occasion#4 are used for retransmission of TB. There is a conflict between PUCCH1 and PUSCH occasion#1. And UCI1 carried by PUCCH1 is transmitted on PUSCH occasion#1, and when there is a conflict between DCI scheduling PUCCH2 and PUSCHoccasion#3, UCI2 carried by PUCCH2 is transmitted on PUSCH occasion#3.

Optionally, in the case where the first UCI is not transmitted on the first PUSCH transmission opportunity, if there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may not multiplex the second UCI. To transmit on the second PUSCH transmission opportunity, for example, the terminal may discard the second UCI, or may transmit the second UCI on the PUCCH.

Alternatively, the terminal may expect that there is a first UCI to be transmitted on the first PUSCH transmission opportunity.

In another embodiment, when the reception time of the downlink control signaling scheduled for the second UCI meets preset conditions, the terminal allows resources to exist between the PUCCH scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity. Conflict, that is, when the reception time of the downlink control signaling scheduled for the second UCI meets preset conditions, the network device may schedule or configure a resource conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity. Specifically, when the reception time of the downlink control signaling scheduled for the second UCI meets the preset conditions, if there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may use the second PUSCH transmission opportunity. The second UCI is sent on the second PUSCH transmission opportunity, that is, the second UCI is multiplexed on the second PUSCH transmission opportunity. It should be noted that the terminal can send all or part of the information of the second UCI on the second PUSCH transmission opportunity.

For example, as shown in Figure 6, PUSCH occasion#1 is used for the initial transmission of TB, PUSCH occasion#2, PUSCHoccasion#3 and PUSCH occasion#4 are used for retransmission of TB. The reception time of DCI scheduled for UCI1 is the same as PUSCHoccasion#. When the interval T1 between the starting moments of 1 is greater than or equal to the preset time interval, if there is a conflict between PUCCH1 carrying UCI1 and PUSCH occasion#3, UCI1 is transmitted on PUSCH occasion#3.

Optionally, when the reception time of the downlink control signaling scheduled for the second UCI does not meet the preset conditions, if there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may not transmit the second UCI. The second UCI is multiplexed and transmitted on the second PUSCH transmission opportunity. For example, the terminal may discard the second UCI, or may transmit the second UCI on the PUCCH.

Optionally, the terminal may expect that the reception time of the downlink control signaling scheduled for the second UCI meets a preset condition.

It should be noted that when the terminal needs to send the second UCI on the second PUSCH transmission opportunity, if the terminal has no data to transmit, the terminal can generate a padding PDU; if the terminal has data to transmit, it can generate a PDU carrying data. .

It should be noted that, in the case where there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may only send PUSCH on the PUSCH retransmission opportunity that conflicts with the PUCCH carrying the UCI. For example, for Figure 5 , PUSCH can be sent only on PUSCH occasion#1 and PUSCH occasion#3, but not PUSCH is sent on PUSCH occasion#2 and PUSCH occasion#4; for Figure 6, PUSCH can be sent only on PUSCH occasion#3, but not on PUSCH occasion#2 and PUSCH occasion#4. PUSCH is not sent on PUSCH occasion#1, PUSCH occasion#2 and PUSCH occasion#4. The terminal can also send PUSCH on the first PUSCH transmission opportunity and all PUSCH transmission opportunities after the first PUSCH transmission opportunity. For example, for Figures 5 and 6, it can be on PUSCH occasion #1, PUSCH occasion #2, PUSCH occasion #3 and PUSCH is sent on PUSCH occasion#4.

The information transmission method provided by the embodiment of the present application is that when the first UCI is transmitted on the first PUSCH transmission opportunity, or the reception time of the downlink control signaling scheduled for the second UCI satisfies the preset conditions, if the second UCI is carried If there is a conflict between the PUCCH of the UCI and the second PUSCH transmission opportunity, the second UCI is sent on the second PUSCH transmission opportunity. In this way, the UCI can be guaranteed when the PUCCH carrying the UCI conflicts with the retransmission resources of the PUSCH. transmission and improve transmission efficiency.

Optionally, the reception time of the downlink control signaling scheduled for the second UCI meets preset conditions, including at least one of the following:

The first time interval between the reception moment of the downlink control signaling scheduled for the second UCI and the first time domain position satisfies the preset duration condition, wherein the first time domain position is determined according to the first PUSCH transmission opportunity. and at least one of the starting time of the PUCCH carrying the second UCI is determined;

The reception time of the downlink control signaling scheduled for the second UCI is before the reception time of the downlink control signaling scheduled for the PUSCH.

In an embodiment, when the time interval between the reception moment of the downlink control signaling scheduled for the second UCI and the first time domain position (ie, the first time interval) satisfies the preset duration condition, the terminal Resource conflicts are allowed between the PUCCH scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity.

Wherein, the reception time of the downlink control signaling of the second UCI may be the start time or the end time of the PDCCH carrying the downlink control signaling. The first time domain position may be determined based on at least one of the first PUSCH transmission opportunity and the starting time of the PUCCH carrying the second UCI. For example, the first time domain position may be the first PUSCH. The start time or end time of the transmission opportunity, or the first time domain position may be the start time of the PUCCH carrying the second UCI, etc. The above preset duration condition can be set according to at least one of PUSCH preparation time, UCI multiplexing time, PDSCH processing time, etc.

In another embodiment, when the reception time of the downlink control signaling that schedules the second UCI is before the reception time of the downlink control signaling that schedules the PUSCH, the terminal is allowed to be scheduled or configured to carry the second UCI. There is a resource conflict between the PUCCH and the second PUSCH transmission opportunity. Wherein, the above-mentioned PUSCH may be a dynamically scheduled PUSCH.

Optionally, the first time domain position may be one of the following:

The starting time of the first PUSCH transmission opportunity;

The starting time of the PUCCH carrying the second UCI;

The earlier of the starting time of the first PUSCH transmission opportunity and the starting time of the PUCCH carrying the second UCI.

In an embodiment, when the first time interval between the reception time of the downlink control signaling scheduled for the second UCI and the start time of the first PUSCH transmission opportunity satisfies the preset duration condition, The terminal allows resource conflicts between the PUCCH scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity.

In another embodiment, the first time interval between the reception time of the downlink control signaling scheduled for the second UCI and the start time of the PUCCH carrying the second UCI satisfies the preset duration condition. Under this condition, the terminal allows resource conflicts between the PUCCH scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity.

In another embodiment, the reception time of the downlink control signaling scheduled for the second UCI may be compared with the starting time of the first PUSCH transmission opportunity and the starting time of the PUCCH carrying the second UCI. If the first time interval between the earlier moments satisfies the preset duration condition, the terminal allows a resource conflict between the PUCCH scheduled or configured to carry the second UCI and the second PUSCH transmission opportunity.

Optionally, the first time interval meeting the preset duration condition may include at least one of the following:

The first time interval is greater than or equal to the PUSCH preparation time;

The first time interval is greater than or equal to the UCI multiplexing time;

The first time interval is greater than or equal to the PDSCH processing time;

In this embodiment, the above PUSCH preparation time is Tproc,1. The above-mentioned UCI multiplexing time may include at least one of a first multiplexing time and a second multiplexing time, wherein the above-mentioned first multiplexing time is Tproc,1+1, and the above-mentioned second multiplexing time is Tproc ,2+1. The above PUCCH preparation time is also N3.

Optionally, the first PUSCH transmission opportunity may be an initial transmission opportunity closest to the second PUSCH transmission opportunity in the PUSCH repeated transmission.

For example, as shown in Figure 7, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of transport blocks, that is, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both the initial transmission of PUSCH repeated transmissions. Opportunities, CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for retransmission of transport blocks, that is, CG PUSCHoccasion#2 and CG PUSCH occasion#4 are both retransmission opportunities in PUSCH repeated transmission, where, CG PUSCHoccasion# There is a resource conflict between 4 and PUCCH2. The initial transmission opportunity closest to CG PUSCH occasion#4 is CGPUSCH occasion#3, that is, the first PUSCH transmission opportunity is CG PUSCH occasion#3.

For another example, as shown in Figure 8, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of transport blocks, CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for retransmission of transport blocks, and CG There is a resource conflict between PUSCHoccasion#4 and PUCCH2. The initial transmission opportunity closest to CG PUSCH occasion#4 is CGPUSCH occasion#3, that is, the first PUSCH transmission opportunity is CG PUSCH occasion#3.

Optionally, the method may also include:

If there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, send PUSCH on the third PUSCH transmission opportunity;

Wherein, the third PUSCH transmission opportunity is a PUSCH transmission opportunity located after the first PUSCH transmission opportunity in the PUSCH repeated transmission, and the third PUSCH transmission opportunity is different from the second PUSCH transmission opportunity.

In this embodiment, the third PUSCH transmission opportunity does not conflict with the PUCCH. Specifically, in the case where there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may transmit all PUSCHs located after the first PUSCH transmission opportunity in the PUSCH repeated transmission. PUSCH is sent on the opportunity, that is, PUSCH is sent on both PUSCH transmission opportunities that conflict with the PUCCH carrying UCI and PUSCH transmission opportunities that do not conflict with the PUCCH carrying UCI.

Optionally, when the reception time of the downlink control signaling scheduled for the second UCI meets the preset conditions, if there is a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity, the terminal may transmit the first PUSCH on the first PUSCH. PUSCH is sent on the transmission opportunity and all PUSCH transmission opportunities after the first PUSCH transmission opportunity. For example, for Figure 8, PUSCH can be sent on both CG PUSCH occasion#3 and CG PUSCH occasion#4.

Optionally, in the case where the first UCI is not transmitted on the first PUSCH transmission opportunity, the terminal does not expect the network device to schedule or configure a conflict between the PUCCH carrying the second UCI and the second PUSCH transmission opportunity.

In this embodiment, in the case where the first UCI is not transmitted on the first PUSCH transmission opportunity, in order to ensure the transmission of UCI, the terminal does not expect the network device to schedule or configure the PUCCH carrying the second UCI and the second PUSCH transmission opportunity. There is a conflict between them.

For example, as shown in Figure 9, since there is no UCI transmission on CG PUSCH occasion#3, that is, the first PUSCH transmission opportunity, the terminal does not expect a conflict between DCI scheduled PUCCH2 and CG PUSCH occasion#4.

For another example, as shown in Figure 10, since there is no UCI transmission on PUSCH occasion#1, that is, the first PUSCH transmission opportunity, the terminal does not expect a conflict between DCI scheduled PUCCH2 and CG PUSCH occasion#3.

Optionally, when the reception time of the downlink control signaling scheduled for the second UCI does not meet the preset conditions, the terminal does not expect the network device to schedule or configure the PUCCH carrying the second UCI and the second PUSCH transmission opportunity. There is a conflict.

In this embodiment, when the reception time of the downlink control signaling scheduled for the second UCI does not meet the preset conditions, in order to ensure the transmission of the UCI, the terminal does not expect the network device to schedule or configure the PUCCH carrying the second UCI and the second UCI. There is a conflict between PUSCH transmission opportunities.

For example, as shown in Figure 11, since the time interval between the reception time of the DCI scheduled for PUCCH1 and the start time of PUSCH occasion#1 does not meet the preset duration condition, the terminal does not expect the DCI scheduled PUCCH1 and CG PUSCHoccasion#3 There is a conflict between them.

In practical applications, when the first UCI is not transmitted on the first PUSCH transmission opportunity or the reception time of the downlink control signaling scheduled for the second UCI does not meet the preset conditions, if the terminal is scheduled or configured to carry the second UCI There is a conflict between the PUCCH and the second PUSCH transmission opportunity, which may cause the second UCI to be unable to be multiplexed on the second PUSCH transmission opportunity. For example, when the terminal's PUSCH has the uplink transmission skip function enabled and the terminal has no data to transmit, in the absence of the first UCI being transmitted on the first PUSCH transmission opportunity, the terminal will determine not to perform PUSCH transmission. If the terminal is scheduled or configured to have a conflict between the PUCCH carrying UCI and the PUSCH retransmission opportunity, the UCI cannot be multiplexed on the PUSCH retransmission opportunity that conflicts with the PUCCH carrying the UCI, resulting in UCI transmission failure. Therefore, in the case where the first UCI is not transmitted on the first PUSCH transmission opportunity, the network device schedules or configures the PUCCH carrying the second UCI and there is no conflict between the second PUSCH transmission opportunity, and the transmission of the UCI can be guaranteed.

Optionally, the transmission priority of the second UCI is the same as the transmission priority of the PUSCH that conflicts with the second UCI;

or

The transmission priority of the second UCI is different from the transmission priority of the PUSCH that conflicts with the second UCI.

or

The transmission priority of the second UCI is different from the transmission priority of the PUSCH that conflicts with the second UCI.

For ease of understanding, the information transmission method provided by the embodiment of the present application is described below with examples. It should be noted that for the following examples, the terminal enables the uplink transmission skipping (UL skipping) function of PUSCH, and PUSCH performs repeated transmissions. .

Example one:

When there is a first UCI multiplexed on the first CG PUSCH transmission opportunity, the UE is allowed to be scheduled or configured with a resource conflict between the second UCI and the second CG PUSCH transmission opportunity, and the UE multiplexes the second UCI on the first CG PUSCH transmission opportunity. On the second CG PUSCH transmission opportunity, the above CG PUSCH is a semi-statically configured PUSCH, where:

The first CG PUSCH transmission opportunity corresponds to the initial transmission opportunity of the TB, that is, the CG PUSCH transmission opportunity corresponding to RV=0. Optionally, the first CG PUSCH transmission opportunity is the last recent CG PUSCH transmission opportunity with RV=0;

The second CG PUSCH transmission opportunity corresponds to the retransmission opportunity of the TB, that is, the CG PUSCH transmission opportunity corresponding to RV≠0;

The second UCI may include one or more UCIs, and the second PUSCH transmission opportunity may include one or more retransmission opportunities for TB repeated transmissions.

For example, as shown in Figure 7, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of the transport block, and CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for the retransmission of the transport block. UCI1 is transmitted on CG PUSCH occasion#3. Therefore, the UE allows resource conflicts between PUCCH2 scheduled by DCI and CG PUSCH occasion#4, and transmits UCI2 carried by PUCCH2 on CG PUSCH occasion#4. It should be noted that for CG PUSCH occasion#1 and CG PUSCH occasion#2, since there is no data transmission and no PUCCH overlaps with them, PUSCH is not sent on CG PUSCH occasion#1 and CG PUSCH occasion#2.

It should be noted that when the first UCI is not multiplexed on the first CG PUSCH transmission opportunity, the UE does not expect to be scheduled or configured with a resource conflict between the second UCI and the second CG PUSCH transmission opportunity. For example, as shown in Figure 9, CGPUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of the transport block, and CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for the retransmission of the transport block. Since there is no UCI is transmitted on CG PUSCH occasion#3. Therefore, the UE does not expect resource conflicts between DCI scheduled PUCCH2 and CG PUSCH occasion#4.

Example two:

When there is a first UCI multiplexed on the first DG PUSCH transmission opportunity, the UE is allowed to have a resource conflict with the second UCI scheduled with the second DG PUSCH transmission opportunity, and the UE multiplexes the second UCI on the second DG PUSCH. On transmission opportunities, the above DG PUSCH can be dynamically scheduled PUSCH, where:

The first PUSCH transmission opportunity is the first transmission opportunity in PUSCH repeated transmission;

The second PUSCH transmission opportunity is a transmission opportunity other than the first transmission opportunity in the PUSCH repeated transmission.

Example three:

When there is no first UCI multiplexed on the first PUSCH transmission opportunity, the UE is not expected to be scheduled or configured with a resource conflict between the second UCI and the second PUSCH transmission opportunity, where:

The first PUSCH transmission opportunity corresponds to the initial transmission opportunity of the TB. Optionally, the first PUSCH transmission opportunity can be the last recent initial transmission opportunity;

The second PUSCH transmission opportunity corresponds to the retransmission opportunity of the TB.

For example, as shown in Figure 10, PUSCH occasion#1 is used for the initial transmission of TB, and PUSCH occasion#2, PUSCHoccasion#3 and PUSCH occasion#4 are used for retransmission of TB. Since PUSCH occasion#1 is the first PUSCH There is no UCI transmission on the transmission opportunity. Therefore, the terminal does not expect a conflict between DCI scheduled PUCCH2 and CG PUSCH occasion#3.

Example four:

When there is a first UCI multiplexed on the first PUSCH transmission opportunity, the UE is allowed to be scheduled or configured with a resource conflict between the second UCI and the second PUSCH transmission opportunity, and the UE multiplexes the second UCI on the second PUSCH. On transmission opportunities, where:

The first PUSCH transmission opportunity corresponds to the initial transmission opportunity of the TB. Optionally, the first PUSCH transmission opportunity can be the last recent initial transmission opportunity;

The second PUSCH transmission opportunity corresponds to the retransmission opportunity of the TB.

In an embodiment, the UE may send PUSCH on the first PUSCH transmission opportunity, and send PUSCH on the second PUSCH transmission opportunity that conflicts with the second UCI.

For example, as shown in Figure 13, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of transport blocks, CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for retransmission of transport blocks, CG PUSCHoccasion There is a resource conflict between #1 and PUCCH1, and there is a resource conflict between CG PUSCH occasion#4 and PUCCH2, so PUSCH is sent on CG PUSCH occasion#1 and CG PUSCH occasion#4.

In another embodiment, the UE sends PUSCH at all PUSCH transmission opportunities after the first PUSCH transmission opportunity (including PUSCH transmission opportunities that conflict with or do not conflict with the second UCI).

For example, as shown in Figure 14, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of transport blocks, CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for retransmission of transport blocks, CG PUSCHoccasion If there is a resource conflict between #1 and PUCCH1, and between CG PUSCH occasion#4 and PUCCH2, it will be sent on CG PUSCH occasion#1, CG PUSCH occasion#2, CG PUSCH occasion#3 and CG PUSCHoccasion#4. PUSCH.

Example five:

When the first time interval between the reception moment of the downlink control signaling scheduled for the second UCI and the first time domain position is greater than or equal to the first duration, the UE is allowed to be scheduled or configured for transmission of the second UCI and the second CG PUSCH. There is a resource conflict between opportunities, and the UE multiplexes the second UCI on the second CG PUSCH transmission opportunity, where:

The first time domain position is the starting time of the first CG PUSCH transmission opportunity;

The first CG PUSCH transmission opportunity corresponds to the initial transmission opportunity of the TB, that is, the CG PUSCH transmission opportunity corresponding to RV=0. Optionally, the first PUSCH transmission opportunity is the last recent CG PUSCH transmission opportunity with RV=0;

The second CG PUSCH transmission opportunity corresponds to the retransmission opportunity of the TB, that is, the CG PUSCH transmission opportunity corresponding to RV≠0;

The first duration is the UCI reuse time;

The UE only transmits PUSCH on the CG PUSCH transmission opportunity that conflicts with the second UCI, or transmits PUSCH on the first CG PUSCH transmission opportunity and all CG PUSCH transmission opportunities after the first CG PUSCH transmission opportunity.

For example, as shown in Figure 8, CG PUSCH occasion#1 and CG PUSCH occasion#3 are both used for the initial transmission of transport blocks, CG PUSCH occasion#2 and CG PUSCH occasion#4 are both used for retransmission of transport blocks, and PUCCH2 is scheduled. The time interval between the reception time of DCI and the starting time of CG PUSCH occasion#3 is greater than or equal to the UCI multiplexing time, then the UE transmits PUSCH on CG occasion#4, or on CG PUSCH occasion#3 and #4 Both transmit PUSCH.

It should be noted that for CG PUSCH occasion#1 and CG PUSCH occasion#2, since there is no data transmission and no PUCCH overlaps with them, PUSCH is not sent on CG PUSCH occasion#1 and CG PUSCH occasion#2.

Example six:

When the time interval between the reception moment of the downlink control signaling scheduled for the second UCI and the first time domain position is greater than or equal to the first duration, the UE is allowed to be scheduled or configured with the second UCI and the second DG PUSCH transmission opportunity. There is a resource conflict between them, and the UE multiplexes the second UCI on the second DG PUSCH transmission opportunity, where:

The first time domain position is the starting time of the first DG PUSCH transmission opportunity;

The first PUSCH transmission opportunity is the first transmission opportunity in PUSCH repeated transmission;

The second PUSCH transmission opportunity is a transmission opportunity other than the first transmission opportunity in PUSCH repeated transmission;

The first duration is the UCI reuse time.

Example seven:

When the time interval between the reception moment of the downlink control signaling scheduled for the second UCI and the first time domain position is less than the first duration, the UE does not expect to be scheduled or configured with resources for the second UCI and the second PUSCH transmission opportunity. Conflict where:

The first time domain position is the starting time of the PUCCH carrying the second UCI, or the first time domain position is the starting time of the first PUSCH transmission opportunity, or the first time domain position is the starting time of the PUCCH carrying the second UCI time and the starting time of the first PUSCH transmission opportunity, whichever is earlier;

The first duration may be at least one of PUSCH preparation time, UCI multiplexing time and PDSCH processing time;

The first PUSCH transmission opportunity corresponds to the initial transmission of the TB, and the second PUSCH transmission opportunity corresponds to the retransmission of the TB.

For example, as shown in Figure 11, since the time interval between the reception time of the DCI scheduled for PUCCH1 and the start time of PUSCH occasion#1 is less than the first duration, the terminal does not expect the time interval between the DCI scheduled PUCCH1 and CG PUSCHoccasion#3. There is a conflict.

Example eight:

For dynamically scheduled PUSCH (including PUSCH repeated transmission), when the reception time of the downlink control signaling scheduled for the second UCI is before the reception time of the downlink control signaling scheduled for the PUSCH, the UE is allowed to be scheduled for the second UCI and the PUSCH. If there is a resource conflict in any repeated transmission, the UE multiplexes the second UCI on the PUSCH transmission opportunity that conflicts with the PUCCH carrying the second UCI.

In one embodiment, the UE only sends PUSCH on PUSCH transmission opportunities that conflict with UCI.

Specifically, PUSCH is sent on the first PUSCH transmission opportunity, and PUSCH is sent on the PUSCH transmission opportunity that conflicts with the second UCI.

In another embodiment, the UE sends PUSCH on all PUSCH transmission opportunities (including PUSCH transmission opportunities that conflict with UCI or do not conflict with UCI).

It should be noted that the information transmission method provided by the embodiments of this application can be applied to single carriers and multiple carriers, as well as licensed frequency bands or unlicensed frequency bands, that is, PUSCH repeated transmission and PUCCH can be on the same carrier or different carriers.
