Description

A method and device for information configuration

technical field

The present invention relates to the wireless field, and in particular, to a method and device for information configuration.

Background technique

With the increase of online video services and the promotion of social networks, mobile traffic in the future will show changeable characteristics: the demand for uplink and downlink services will change with time and location, and the existing communication system adopts a relatively fixed spectrum resource allocation method, which can no longer be satisfied. The service requirements of different cells vary. Therefore, the flexible duplex technology is widely used due to its advantages of being able to dynamically allocate uplink and downlink resources according to changes in uplink and downlink services, and to effectively improve system resource utilization.

The flexible duplex technology can dynamically configure the uplink and downlink transmission directions of the frame structure according to the service status of the terminal in the cell. However, when adjacent cells transmit information in different directions (uplink or downlink) on the same time-frequency resource, network-side equipment will be generated. The problem of cross-link interference with network-side equipment and between terminals.

At present, when measuring the cross-link interference between terminals in flexible duplex, the network-side devices need to exchange the uplink and downlink information of the frame structure to be configured. The line information can accurately determine the interference source (uplink) terminal and the interfered (downlink) terminal of the cross-link interference. At this time, when performing cross-link interference measurement, only the interference source terminal needs to send the measurement reference signal, and the interfered terminal receives the measurement The reference signal can be used for cross-link interference measurement.

However, the frame structure for the interaction between the network side devices is to configure the uplink and downlink information, and it is not specified whether the exchanged information is determined uplink, downlink or flexible frame structure information. If the frame structure of the interaction between the network-side devices is to be configured with the uplink and downlink information as a flexible frame structure, the interference source terminal and the interfered terminal cannot be accurately determined at this time, and the terminals need to perform CLI (cross link interference, cross-link interference). Link interference) measurement, in the case of many terminals or terminal groups, the network side equipment needs to frequently exchange information such as the configuration of the reference signal for the CLI measurement of the terminal, which will also cause the CLI measurement period to be too long.

To sum up, when the prior art performs CLI measurement, the signaling overhead is relatively large and the period is too long.

The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in FIG. 1 , an information configuration method and device according to an embodiment of the present invention include: a network side device 10 and a terminal 20 .

The network side device 10 determines the joint transmission and reception indication information of the cross-link interference CLI measurement reference signal corresponding to the terminal or terminal group, wherein the joint transmission and reception indication information is used to indicate that the terminal or terminal group is used for the sounding reference signal SRS resource corresponding to the SRS resource. The CLI measurement reference signal is sent on the sent symbol, and the CLI measurement reference signal is received on the received symbol corresponding to the SRS resource; the joint indication information is sent to the terminal or terminal group.

The terminal 20 is configured to receive the joint transmission and reception indication information configured by the network side equipment for the terminal or the terminal group; according to the joint transmission and reception indication information, send the CLI measurement reference signal on the symbol used for transmission corresponding to the SRS resource, and send the CLI measurement reference signal on the symbol corresponding to the SRS resource. The CLI measurement reference signal is received on the received symbol.

Through the above solution, the network side device determines the joint sending and receiving indication information of the CLI measurement reference signal corresponding to the terminal or terminal group, and the terminal completes the sending and receiving instructions on the symbol corresponding to the SRS resource according to the joint sending and receiving instruction information determined by the network side device. Other terminals or terminal groups simultaneously send CLI measurement reference signals or simultaneously receive CLI measurement reference signals sent by other terminals or terminal groups, thereby completing all CLI measurements with other terminals or terminal groups. The network-side equipment does not need to configure the terminal or terminal group to send and receive CLI measurement reference signals individually, so that the network-side equipment does not need to frequently exchange CLI measurement configuration information, saving signaling overhead. Further, the present invention implements For example, since the measurement signal can be sent and received jointly, the CLI measurement duration is correspondingly reduced.

In this embodiment of the present invention, when a terminal performs CLI measurement, there are various types of CLI measurement reference signals sent or received between terminals or terminal groups. For example, the terminal may use SRS as a CLI measurement reference signal.

In implementation, the terminal or terminal group may be used as the granularity, and when the terminal is used as the granularity, the network side device configures the terminals in the serving cell;

When the terminal group is used as the granularity, the network side device can divide the terminals with the same transmission direction in the serving cell into terminal groups, that is, the same uplink terminals or the same downlink terminals, and configure the terminal groups in the serving cell.

The network side device may configure the SRS resource set within one SRS joint sending and receiving period of the terminal. The SRS resource set includes N SRS resources, where N is a positive integer and not less than the number of terminals performing CLI measurement. Each SRS resource has a corresponding SRS resource identifier, and one SRS resource may include 1, 2 or 4 symbols. Several possible SRS configuration methods are given below.

As shown in FIG. 2 , it is a schematic diagram of SRS resource configuration provided by an embodiment of the present invention.

Wherein, A indicates that the SRS resource set includes one SRS resource, and the SRS resource occupies a position of one symbol, that is, the SRS resource is a single symbol; B indicates a dual-symbol SRS resource in the SRS resource set. Wherein, ID1 is the identifier of the SRS resource.

The time domain nature of the SRS resource set is periodic or semi-persistent periodic or aperiodic.

In the embodiment of the present invention, the network side device configures two types of SRS transmission for the terminal, as follows:

1. Periodic SRS.

Periodic SRS transmission is sent once every certain period, and the terminal performs periodic SRS cycle according to the SRS resource set configuration information sent by the network side device without triggering. The following examples illustrate:

As shown in FIG. 3 , it is a schematic diagram of a periodic SRS resource set configured for a terminal by a network side device according to an embodiment of the present invention.

An SRS resource set located in slot 1 configured by the network side device for the terminal, wherein the SRS resource set includes a single-symbol SRS resource.

The configuration period of the SRS resource is 10 slots, that is, every 10 slots, the terminal sends or receives the SRS resource on the symbol identified as ID1 once. The terminal sends or receives SRS resources on the symbol identified as ID1 in slot1, and the terminal is used for the normal communication process in slot2 to slot10, and in slot11, it sends or receives SRS resources again on the symbol identified as ID1, to this cycle.

2. Semi-persistent periodic SRS.

For the configuration of the semi-persistent periodic SRS, please refer to the configuration of the periodic SRS. The difference is that the semi-persistent periodic SRS is not an infinite loop. The transmission of the semi-persistent period SRS is activated.

Among them, activation means that the terminal triggers a semi-persistent SRS cycle after receiving a MAC CE active (activation) signaling sent by the network side device; deactivation means that the terminal receives a MAC CE deactive signal sent by the network side device. The semi-persistent SRS cycle is stopped after (inactive) signaling.

As shown in FIG. 4 , it is a schematic diagram of a semi-persistent period SRS configuration that is triggered by the network side device and that the terminal cycles twice.

The terminal triggers a semi-persistent periodic SRS cycle after receiving active from the network-side device, and stops the semi-persistent periodic SRS cycle after receiving the network-side device sending inactive after the second cycle of the cycle.

In this embodiment of the present invention, the network side device configures, through RRC, an SRS resource set whose time domain property is periodic or semi-persistent periodic for a terminal or terminal group in a serving cell; wherein, the time domain of the SRS resource included in the SRS resource set The properties are the same as the time domain properties of the SRS resource set.

After the network side device configures the SRS resource set, the function of setting the SRS resource set is also used for cross-link interference measurement.

In implementation, the network side device sets the function of the SRS resource set to CLI measurement through RRC signaling, so that the terminal sends SRS resources to other terminals or receives SRS sent by other terminals within one SRS joint transmission and reception cycle resource.

The SRS joint transmission and reception period refers to that when the function of the SRS resource set is cross-link interference (CLI) measurement, the terminal sends the CLI measurement reference on the symbol used for transmission corresponding to the SRS resource according to the joint indication information signal, and the CLI measurement reference signal is received on the symbol for reception corresponding to the SRS resource.

It should be noted that when the function of the SRS resource set configured by the network side device for the terminal is cross-link interference (CLI) measurement, the network side also needs to communicate with other terminals that need to perform CLI measurement. The side device sends indication information including the configuration of the SRS resource set, which is used to ensure that the configuration of the SRS resource set configured by other network side devices for the serving terminal is the same, so as to complete the CLI synchronization measurement between terminals.

In this embodiment of the present invention, in one SRS joint transmission and reception cycle, the number of SRS resources configured by different terminals or different terminal groups is the same, and in one SRS joint transmission and reception cycle, different terminals or different terminal groups correspond to the same SRS resource identifier, and the same SRS resource identifier The corresponding SRS resource includes the same number of symbols, time-frequency resource location and time slot offset configuration.

For example, there are two terminal groups belonging to two different cells respectively, one terminal group is represented as UE1, and the other terminal group is represented as UE2. The base stations of the two cells exchange the indication information SFI of the subframe uplink and downlink transmission directions through the Xn interface. To ensure that the SRS resource sets configured for the terminal groups in different cells are the same, and the SFI indicates that the frame structures of the three cells are all flexible frames At this time, the interference source cell terminal group and the interfered cell terminal group cannot be distinguished. At this time, the two terminal groups need to perform cross-link interference measurement respectively, and UE1 and UE2 can apply the embodiment of the present invention to perform SRS joint transmission and reception.

As shown in FIG. 5 , an embodiment of the present invention provides a schematic diagram of configuring SRS resource sets for two terminals and performing SRS resource interaction within one SRS joint sending and receiving period.

The network side device configures the SRS resource set through RRC signaling, sets the function of the SRS resource set as CLI measurement, and sends the configuration information to the terminal through RRC signaling. Correspondingly, UE1 and UE2 determine, according to receiving the RRC signaling, that the function of the SRS resource set configured by the network side device is cross-link interference measurement.

Wherein, slot1 is a slot used by UE1 and UE2 for sending or receiving measurement reference signals in one SRS joint transmission and reception cycle of the SRS resource.

The SRS resource set configured by the UE1 in one SRS joint transmission and reception cycle includes two single-symbol SRS resources, and the SRS resource identifiers are ID1 and ID2 respectively. And in one SRS joint transmission and reception period, UE1 and UE2 have the same SRS resource set configuration, that is, UE1 and UE2 have the same number of SRS resources in one SRS joint transmission and reception period, and UE1 and UE2 correspond to the same SRS resources in one SRS joint transmission and reception period and the SRS resource corresponding to the same SRS resource identifier includes the same number of symbols, time-frequency resource location and time slot offset configuration.

Suppose, UE1 sends SRS resources on the ID1 symbol within the SRS joint transceiving period; and receives SRS resources on the ID2 symbol.

Correspondingly, UE2 needs to receive SRS resources on the ID1 symbol within the SRS joint transceiving period; and send SRS resources on the ID2 symbol.

In this embodiment of the present invention, if the same terminal or terminal group has multiple SRS resources for transmission and/or reception in the same time slot, the configuration between adjacent SRS resources includes a guard interval of N symbols, where N is a positive integer, so The terminal does not transmit any signal during the guard interval.

For example, if UE1 transmits and/or receives two SRS resources in slot1, a guard interval (gp) of at least one symbol needs to be configured between the two SRS resources.

Among them, the value of N in the guard interval between SRS resources is related to the subcarrier spacing (numerology), and the specific relationship is shown in Table 1 below:

μ Δf=2^μ·15[kHz] N[symbol] 0 15 1 1 30 1 2 60 1 3 120 2

Table 1

Among them, μ is the subcarrier spacing configuration, and Δf is the subcarrier spacing.

It should be noted that the above-mentioned transmission mode of the SRS resource by the terminal on the symbols included in the SRS resource is only an example. In the embodiment of the present invention, the network side device determines the joint sending and receiving indication information of the CLI measurement reference signal corresponding to the terminal or the terminal group, It is used to instruct the terminal or terminal group to send the CLI measurement reference signal on the symbol used for transmission corresponding to the sounding reference signal SRS resource, and to receive the CLI measurement reference signal on the symbol used for reception corresponding to the SRS resource.

In this embodiment of the present invention, the network side device sends the joint sending and receiving indication information to the terminal or terminal group through RRC signaling.

Correspondingly, the terminal receives the joint sending and receiving indication information configured for the terminal or the terminal group and sent by the network side device through RRC signaling.

The joint transmission and reception indication information is a bitmap; wherein the number of bits of the bitmap is determined according to the number of SRS resources of the CLI measurement reference signal of the terminal or terminal group in one SRS resource joint transmission and reception cycle, and the corresponding number of bits in the bitmap is determined. The value status on the bit indicates that the CLI measurement reference signal is sent or received on the symbol included in the SRS resource corresponding to the bit.

Correspondingly, the terminal sends or receives the CLI measurement reference signal on the symbol included in the SRS resource corresponding to the bit according to the value of the bit in the bitmap.

For example, if the number of SRS resources in a joint transmission and reception cycle of SRS resources is 3, the number of bits in the bitmap is 3, and the 3 bits in the bitmap correspond to the symbols included in SRS resource 1, the symbols included in SRS resource 2, and the symbols included in SRS resource 3, respectively. symbol. The value on the corresponding bit in the bitmap indicates that the CLI measurement reference signal is sent or received on the symbol included in the SRS resource corresponding to the bit. The following is an example of the transmission mode of the CLI measurement reference signal corresponding to the value of the corresponding bit in the bitmap:

Mode 1: When the value is 1, it means sending; when the value is 0, it means receiving.

When the value of the bit is 1, it indicates that the terminal sends the CLI measurement reference signal on the symbol included in the SRS resource corresponding to the bit.
