[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202310884426.7 filed in China on July 18, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to a CSI reporting method, a terminal and a network-side device, an electronic device, and a medium. Background Art

[0004] In the SubBand non-overlapping FullDuplex (SBFD) technology, the downlink resources available to the terminal are different in different time slot types. For example, in the SBFD time slot, the terminal can only use the frequency domain resources of the downlink (DL) subband for downlink reception (not the full downlink bandwidth). In the non-SBFD time slot, the terminal can perform downlink reception on the DL bandwidth part (Bandwidth Part, BWP) with a larger frequency domain resource range, such as the full downlink bandwidth. The downlink power in the SBFD time slot and the non-SBFD time slot may also be different. In addition, the interference situation in the SBFD time slot and the non-SBFD time slot is also different. The terminal will be subject to cross-link interference (CLI) from other terminals in the SBFD time slot.

[0005] A periodic or semi-persistent Channel State Information-Reference Signal (CSI-RS) can appear in both SBFD and non-SBFD time slots in the time domain. According to existing CSI reporting methods, the terminal averages multiple measurement results on the periodic or semi-persistent CSI-RS (that is, the average of the measurement results of the same CSI-RS measured in SBFD and non-SBFD time slots) before reporting. This makes it impossible for the base station to distinguish the true channel state information.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0026] Referring to FIG. 1 , FIG. 1 is a flowchart of a method for reporting channel state information (CSI) provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 1 , the method includes the following steps:

[0027] Step 101: Receive a CSI reporting configuration configured by a network-side device, where the CSI reporting configuration includes at least one of the following configurations: a channel measurement resource (CMR), two CSI interference measurement (IM) resources for interference measurement, and one or two reporting resources; the time domain location of the channel measurement resource includes at least one of the following types: a first time type and a second time type;

[0028] Optionally, the first time type in the embodiment of the present disclosure includes at least one of the following: sub-band full-duplex (SBFD) time slots and / or symbols, and time slots and / or symbols configured with uplink frequency domain resources and / or downlink frequency domain resources. The second time type includes at least one of the following: non-SBFD time slots and / or symbols, and time slots and / or symbols not configured with uplink frequency domain resources and / or downlink frequency domain resources.

[0029] Step 102: Perform CSI reporting based on the CSI reporting configuration.

[0030] As can be seen from the above steps 101 and 102 of the embodiment of the present disclosure, in the embodiment of the present disclosure, the terminal can receive a CSI reporting configuration configured by a network-side device. Based on the CSI reporting configuration, where the CSI reporting configuration includes at least one of the following configurations: one channel measurement resource, two CSI IM resources for interference measurement, and one or two reporting resources; and the time domain location of the channel measurement resource includes at least one of the following types: a first time type and a second time type. The terminal can measure the reference signal at corresponding different time types (the first time type and the second time type), that is, can obtain two measurement results (a first measurement result and a second measurement result). These two measurement results can be reported based on one or two reporting resources, rather than averaging the two measurement results before reporting. This solves the problem in the related art where the terminal averages CSI-RS measurement results at different time types, that is, averages the measurement results of periodic or semi-persistent CSI-RS at different time types before reporting, resulting in the base station being unable to distinguish the true channel state information.

[0031] In an optional implementation manner of the embodiment of the present disclosure, when the time domain location of the channel measurement resource includes a first time type and a second time type, the manner of performing CSI reporting based on the CSI reporting configuration involved in the above step 102 may further include:

[0032] Step 11, measuring a reference signal at a first time type and a second time type respectively, to obtain a first measurement result corresponding to the first time type and a second measurement result corresponding to the second time type;

[0033] Step 12: Report the first measurement result and the second measurement result based on one reporting resource, or report the first measurement result and the second measurement result respectively based on two reporting resources.

[0034] It can be seen that in the embodiment of the present disclosure, if there is only one reporting resource currently, the two measurement results obtained based on the two measurement results of different time types (the first time type and the second event type) are reported separately, rather than averaging the two measurement results for reporting. That is, the network side device can distinguish the corresponding measurement results. If there are two reporting resources currently, the two measurement results are reported separately based on the two reporting resources. Since one measurement result is reported by one reporting resource, it is easier for the network side to distinguish the corresponding measurement results. It should be noted that the first time type in the embodiment of the present disclosure can be an SBFD time slot and / or SBFD symbol, and the second time type is a non-SBFD time slot and / or SBFD symbol; or, if the first time type is a time slot and / or symbol configured with uplink frequency domain resources (uplink subband) and / or downlink frequency domain resources (downlink subband), the second time type is a time slot and / or symbol not configured with uplink frequency domain resources (uplink subband) and / or downlink frequency domain resources (downlink subband).

[0035] In the embodiment of the present disclosure, when the CSI reporting configuration includes two CSI IM resources for interference measurement, the manner of performing CSI reporting based on the CSI reporting configuration involved in step 102 may further include:

[0036] Step 21: Obtain, based on the two CSI IM resources, a third measurement result corresponding to the first CSI IM resource and a fourth measurement result corresponding to the second CSI IM resource; wherein the two CSI IM resources used for interference measurement include the first CSI IM resource and the second CSI IM resource;

[0037] Step 22: Report the third measurement result and the fourth measurement result based on one reporting resource; or, report one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result based on one reporting resource; or, report the third measurement result and the fourth measurement result respectively based on two reporting resources.

[0038] It can be seen that in the embodiment of the present disclosure, for the two measurement results (the third measurement result and the fourth measurement result) obtained based on the two CSI IM resources for interference measurement, the two measurement results can be reported based on one reporting resource instead of averaging the two measurement results for reporting. Alternatively, they can be reported separately based on the two reporting resources. Since one measurement result is reported using one reporting resource, it is easier for the network side to distinguish the corresponding measurement results.

[0039] In an optional implementation manner of an embodiment of the present disclosure, for the manner of reporting the first measurement result and the second measurement result based on one reporting resource involved in step 12 above, the packet may include at least one of the following:

[0040] Step 31: reporting the first information for identifying the first measurement result and the first measurement result, and the second information for identifying the second measurement result and the second measurement result;

[0041] Step 32: Report the first measurement result and the second measurement result based on a protocol predefined order, wherein the protocol predefined order refers to the order of the first measurement result and the second measurement result in the reporting information of the terminal;

[0042] As can be seen, in the embodiments of the present disclosure, even if reporting is currently performed based on a single reporting resource, it is possible to distinguish between the first measurement result and the second measurement result by carrying information corresponding to different measurement results. Furthermore, in a specific example, the protocol-predefined order means that the first measurement result is reported based on a single reporting resource first, followed by the second measurement result being reported based on a single reporting resource; or, alternatively, the protocol-predefined order means that the second measurement result is reported based on a single reporting resource first, followed by the first measurement result being reported based on a single reporting resource. Therefore, if the reporting order is known in advance, it is possible to determine whether the currently received measurement result is the first measurement result or the second measurement result based on the reception order.

[0043] In this regard, in the case where there is only one reporting resource in the embodiment of the present disclosure, the above steps 31 and 32 can be, in a specific example: the CSI content reported by the terminal carries a flag (identifier) ​​and a measurement result, such as 0SINR#1, 1SINR#2, where "0" and "1" are flags, respectively representing whether the time type corresponding to the signal to interference plus noise ratio (SINR) measurement result is the first time type or the second time type. Among them, "0" and "1" are the first information and the second information, and whether the first information is 0 or 1 can be set accordingly according to actual needs.

[0044] For protocol pre-definition, it is pre-defined that the terminal first reports the measurement results of the first time type, and then reports the measurement results of the second time type. For example, the terminal reports SINR#1 and SINR#2, where SINR#1 corresponds to the measurement results of the first time type, and SINR#2 corresponds to the measurement results of the second time type. Alternatively, it is pre-defined that the terminal first reports the measurement results of the second time type, and then reports the measurement results of the first time type. For example, the terminal reports SINR#1 and SINR#2, where SINR#1 corresponds to the measurement results of the second time type, and SINR#2 corresponds to the measurement results of the first time type.

[0045] In an optional implementation manner of an embodiment of the present disclosure, the method of reporting the first measurement result and the second measurement result based on the two reporting resources involved in the above step 12 may further include: reporting the first measurement result on one of the two reporting resources, and reporting the second measurement result on the other reporting resource of the two reporting resources other than the reporting resource for reporting the first measurement result; wherein the correspondence between the two reporting resources and the first measurement result and the second measurement result is predefined by the network side device configuration or protocol.

[0046] In this regard, in a specific example, when there are two reporting resources in the embodiment of the present disclosure, the network side device is configured or the protocol is predefined, and the terminal reports the measurement results of the first time type on reporting resource #1 (Physical Uplink Control Channel (PUCCH) #1), and then reports the measurement results of the second time type on reporting resource #2 (PUCCH #2), or the terminal reports the measurement results of the second time type on reporting resource #1 (PUCCH #1), and reports the measurement results of the first time type on reporting resource #2 (PUCCH #2).

[0047] In an optional implementation manner of the embodiment of the present disclosure, the manner of reporting the third measurement result and the fourth measurement result based on one reporting resource involved in step 22 includes one of the following:

[0048] Step 41: reporting the third information for identifying the third measurement result and the third measurement result, and the fourth information for identifying the fourth measurement result and the fourth measurement result;

[0049] Step 42: Report the third measurement result and the fourth measurement result based on a protocol predefined order, where the protocol predefined order refers to the order of the third measurement result and the fourth measurement result in the reporting information of the terminal;

[0050] And the method of reporting one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result based on one reporting resource involved in step 22 includes:

[0051] Step 43: Report one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result based on the protocol predefined order, wherein the protocol predefined order refers to the order of one of the third measurement result and the fourth measurement result, and the difference between the third measurement result and the fourth measurement result in the reporting information of the terminal.

[0052] In a specific example, when there is only one reporting resource in the embodiment of the present disclosure, the above steps 41 and 42 may be: the CSI content reported by the terminal carries a flag (identifier) ​​+ measurement result, for example, 0SINR#1, 1SINR#2, where "0" and "1" are flags, respectively representing whether the time type corresponding to the SINR measurement result is the measurement result of CSI-IM resource #1 or the measurement result of CSI-IM resource #2.

[0053] For protocol pre-definition, it can be pre-defined that the terminal first reports the measurement result on CSI-IM resource #1, then the measurement result on CSI-IM resource #2. Therefore, the terminal reports SINR#1 and SINR#2, where SINR#1 corresponds to the measurement result on CSI-IM resource #1, and SINR#1 corresponds to the measurement result on CSI-IM resource #2. Alternatively, it can be pre-defined that the terminal first reports the measurement result on CSI-IM resource #2, then the measurement result on CSI-IM resource #1. Therefore, the terminal reports SINR#1 and SINR#2, where SINR#1 corresponds to the measurement result on CSI-IM resource #2, and SINR#1 corresponds to the measurement result on CSI-IM resource #1. In this regard, in an SBFD system, CSI-IM resource #1 may only include inter-cell interference measurement, with no other terminals transmitting uplink signals, while CSI-IM resource #2 may include other terminals transmitting uplink signals, including both inter-cell interference measurement and inter-terminal cross-link interference measurement. Based on this, the network-side device obtains the measurement results on the two CSI-IM resources and knows the interference situation between terminals in the SBFD timeslot.

[0054] For the above step 43, in a specific example, if the terminal reports the measurement result on CSI-IM resource #1, it also reports the difference between the measurement result on CSI-IM resource #1 and the measurement result on CSI-IM resource #2. If in the SBFD system, CSI-IM resource #1 only includes inter-cell interference measurement, and no other terminal sends uplink, on CSI-IM resource #2, there are other terminals sending uplink, including both inter-cell interference measurement and cross-link interference measurement between terminals. Therefore, the network-side device obtains the difference between the measurement results on these two CSI-IM resources, and knows the interference situation between terminals in the SBFD time slot.

[0055] In an optional implementation manner of the embodiment of the present disclosure, the manner of reporting the third measurement result and the fourth measurement result based on two reporting resources involved in step 22 may further include:

[0056] Step 51: Report the third measurement result in one of the two reporting resources, and report the fourth measurement result in the other reporting resource of the two reporting resources except the reporting resource for reporting the third measurement result; wherein the correspondence between the two reporting resources and the third measurement result and the fourth measurement result is predefined by the network side device configuration or protocol.

[0057] In this regard, in a specific example, when there are two reporting resources in the embodiment of the present disclosure, the network side device is configured or the protocol is predefined, and the terminal reports the measurement result on CSI-IM resource #1 on reporting resource #1 (PUCCH#1), and reports the measurement result on CSI-IM resource #2 on reporting resource #2 (PUCCH#2); or, the terminal reports the measurement result on CSI-IM resource #2 on reporting resource #1 (PUCCH#1), and reports the measurement result on CSI-IM resource #1 on reporting resource #2 (PUCCH#2).

[0058] In an optional implementation manner of the embodiment of the present disclosure, the method of the embodiment of the present disclosure may further include:

[0059] Step 103: Receive a time restriction (timeRestrictionForChannelMeasurements) configured by a network-side device for indicating a channel measurement, wherein the time restriction is used to indicate that channel measurement is performed on a measurement resource closest to the first time type or the second time type.

[0060] It can be seen that if the network side configures a time limit for channel measurement for the terminal, the terminal can obtain the measurement result according to the latest reference signal in the first time type or the second time type respectively.

[0061] Referring to FIG. 2 , FIG. 2 is a flowchart of a CSI reporting method provided by an embodiment of the present disclosure, which is used for a network-side device. As shown in FIG. 2 , the method includes the following steps:

[0062] Step 201: Configure a CSI reporting configuration, where the CSI reporting configuration includes at least one of the following configurations: one channel measurement resource, two CSI IM resources for interference measurement, and one or two reporting resources; the time domain location of the channel measurement resource includes at least one of the following types: a first time type and a second time type;

[0063] Step 202: Send a CSI reporting configuration to the terminal, and receive a CSI result reported by the terminal based on the CSI reporting configuration.

[0064] For the above optional implementation manner, reference may be made to the relevant description in the embodiment shown in FIG1 . To avoid repeated description, this embodiment will not be described in detail.

[0065] It should be noted that the embodiment of the present disclosure provides a CSI reporting method performed by a network-side device corresponding to the embodiment of the CSI reporting method performed by the terminal shown in Figure 1 above. All implementation methods in the embodiment of the CSI reporting method performed by the above-mentioned terminal are applicable to the CSI reporting method performed by the network-side device, and can achieve the same or similar beneficial effects.

[0066] Referring to FIG. 3 , FIG. 3 is a schematic diagram of the structure of a terminal provided by an embodiment of the present disclosure. As shown in FIG. 3 , the terminal 300 includes:

[0067] A first receiving module 302 is configured to receive a CSI reporting configuration configured by a network-side device, wherein the CSI reporting configuration includes at least one of the following configurations: one channel measurement resource, two CSI IM resources for interference measurement, and one or two reporting resources; and the time domain location of the channel measurement resource includes at least one of the following types: a first time type and a second time type;

[0068] The reporting module 304 is configured to perform CSI reporting based on the CSI reporting configuration.

The terminal can measure the reference signal at the corresponding different time types (the first time type and the second time type), that is, it can obtain two measurement results (the first measurement result and the second measurement result), and the two measurement results can be reported based on one or two reporting resources, rather than averaging the two measurement results and then reporting them, thereby solving the problem in the related art that the terminal averages the measurement results of the CSI-RS on different time types and then reports them, resulting in the base station being unable to distinguish the true channel state information.

Bus 401 links various circuits together, including one or more processors represented by processor 405 and memory represented by memory 406.
