As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0018] First, the related terms in the implementation of this application are interpreted.

[0019] I. Multi-TRP Transmission Technology 3GPP (registered trademark) Rel-16 standardizes the multi-transmission point / multi-antenna panel (multi-TRP / multi-panel) scenario, which can improve the reliability and throughput performance of transmission. For example, a UE can receive the same data or different data from multiple TRPs. The multi-TRPs can be divided into an ideal backhaul and a non-ideal backhaul. In the non-ideal backhaul, there is a relatively large delay in the interaction information between multi-TRPs, which is relatively suitable for independent scheduling. The ACK / NACK and CSI reports are fed back to each TRP respectively. Generally, it is applied to multi-downlink control information (DCI) scheduling. That is, each TRP transmits its own physical downlink control channel (PDCCH), and each PDCCH schedules its own physical downlink shared channel (PDSCH). The multiple control resource sets (CORESET) arranged for the UE are associated with different radio resource control (RRC) parameters CORESETPoolIndex and correspond to different TRPs. The multiple PDSCHs scheduled by multiple DCIs may not overlap, may partially overlap, or may completely overlap in time-frequency resources. In the overlapping time-frequency resources, each TRP performs precoding independently based on its own channel, and the UE receives the multi-layer data streams belonging to multiple PDSCHs in the manner of non-coherent joint transmission (NCJT).

[0020] In an ideal backhaul link, scheduling information and UE feedback information can be interacted in real time among multiple TRPs. In addition to being able to schedule multiple PDSCHs by the above-mentioned multi-DCI, a PDSCH can also be scheduled by a single DCI, including the following several transmission schemes.

[0021] 1) Space Domain Scheduling (SDM): Different data layers of the same TB (Transport Block) are from NCJT transmissions of different TRPs. 2) Frequency Domain Scheduling (FDM): Different frequency domain resources mapped to the same redundant version (RV) of the same TB are transmitted from different TRPs, or different RVs of the same TB are mapped to different frequency domain resources and transmitted from different TRPs. 3) Time Domain Scheduling (TDM): Multiple repetitions of different RVs of the same TB are from different TRPs, such as repetitions within one slot or repetitions from multiple slots.

[0022] At this time, ACK / NACK feedback and CSI reports can be fed back to any one of the TRPs.

[0023] II. CSI Report Configuration of Rel-16 Single TRP · Periodic CSI report (P-CSI): Transmitted only on PUCCH. · Semi-persistent CSI report (SP-CSI): Transmitted on PUCCH or PUSCH. · Aperiodic CSI report (AP-CSI): Transmitted only on PUSCH.

[0024] III. Rel-16 CSI Reporting Mechanism Based on PUSCH The CSI report based on PUSCH supports Type1 wideband or sub-band CSI and also supports Type2 CSI.

[0025] Regarding Type1, Type2, and enhanced Type2 CSI feedback based on PUSCH, one CSI report is composed of two parts (Part1 and Part2). Here, Part1 has a certain load magnitude and indicates the number of information bits in Part2. It should be noted that Part1 is transmitted before all of Part2.

[0026] Regarding Type1 CSI feedback, Part1 includes one or more of RI (Rank Indicator), CRI (CSI-RS Resource Indicator), and the CQI of the first codeword, and Part2 includes one or more of PMI and the CQI of the second codeword.

[0027] Regarding Type2 CSI feedback, Part1 includes one or more of RI, Channel quality indicator (CQI), and the non-zero wideband amplitude coefficient indicator of each layer of Type2 CSI, and Part2 includes the PMI of Type2 CSI.

[0028] Regarding enhanced Type2 CSI feedback, Part1 includes RI, CQI, and an indication of the total number of non-zero amplitude coefficients between enhanced Type2 CSI layers, and Type2 includes the Precoding Matrix Indicator (PMI) of enhanced Type2 CSI.

[0029] When the CSI based on PUSCH reports includes Part1 and Part2, the UE can delete the content of some Part2 CSI. Here, for the enhanced Type2 CSI report, Group 0 includes the index i 1,1 , i 1,2 and i 1,8,l (l = 1, …, v), Group 1 includes the index i 1,5 (if reported), i 1,6,l , the high-priority part i 1,7,l , i 2,3,l , the high-priority part i 2,4,l , the high-priority part i 2,5,l (l = 1, …, v), Group 2 includes the low-priority part i 1,7,l , the low-priority part i 2,4,l , the low-priority part i 2,5,l (l = 1, …, v). The interpretation of the specific feedback amount is shown in Table 1 and Table 2.

[0032] IV. Rel-16 CSI reporting mechanism based on PUCCH Periodic CSI reporting based on PUCCH format 2, 3, 4 supports wideband Type1 CSI, Semi-persistent CSI reporting based on PUCCH supports Type1 CSI, Semi-persistent CSI reporting based on PUCCH format 2 supports wideband Type1 CSI, Semi-persistent CSI reporting based on PUCCH format 3 or 4 supports wideband and sub-band Type1 CSI and Type2 CSI Part1, When the sub-band Type1 CSI is reported based on PUCCH format 3 or 4, the CSI load is divided into two parts (Part1 and Part2). Part1 includes RI, CRI, and some or all of the CQI corresponding to the first codeword. Part2 includes PMI and the CQI corresponding to the second codeword (when RI > 4, there are two codewords). When a CSI report contains two parts, the UE can delete the content of some Part2 CSI, and the priority order is consistent with the priority based on the PUSCH report.

[0033] V. Potential CSI Frameworks for Multi-TRP In the current protocol, for multi-TRP / multi-panel, it is specifically defined in terms of CSI report configuration, report content, and CSI resource configuration, etc. Specifically, there are the following multiple methods.

[0034] 1) Arrange multiple CSI Reporting Settings, and the resource setting of each Reporting Setting corresponds to one TRP, that is, each CSI Reporting Setting corresponds to the CSI report of one TRP.

[0035] 2) The base station arranges one CSI Reporting Setting, and by default or instructs that multiple CSI resource settings or multiple CSI resources cooperate (work together) to calculate one CSI report. Especially in the cooperative calculation of one CQI, in one CSI report, based on the CSI resource setting or CSI resource determined by the CRI, one PMI and / or RI can be obtained, and further based on these PMI / RI, one CQI (the meaning of one CQI: according to the definition of the conventional protocol, it may include the wideband or sub-band CQI of 1 to 2 codewords) can be determined respectively or cooperatively (jointly).

[0036] 3) The terminal includes CSI of DPS corresponding to one TRP in the CSI report and indication information of another TRP for instructing another TRP not to schedule this terminal, and / or feeds back to a plurality of TRPs that it includes CSI corresponding to at least two TRPs. Here, each TRP fed back from the terminal corresponds to the CSI of NCJT.

[0037] 4) The network can arrange for the terminal to report a certain type of CSI or to report multiple types of CSI.

[0038] 5) The CSI report may include TRP information corresponding to multiple TRPs for the CSI.

[0039] In the following, the method for processing channel state information according to the embodiments of the present application will be described in detail with reference to specific embodiments and their application scenarios while combining with the drawings.

[0040] FIG. 2 is a flowchart of a method for processing channel state information according to an embodiment of the present application. This method is executed by a terminal. As shown in FIG. 2, the steps of this method include the following steps.

[0041] S202, Transmit a multi-transmission point channel state information MTRP CSI report to a multi-transmission point MTRP based on the uplink channel. Here, the MTRP CSI report includes a plurality of CSIs.

[0042] According to S202 of the embodiment of the present application, since the MTRP CSI report includes a plurality of CSIs, by transmitting this MTRP CSI report to the MTRP, it is realized that a plurality of CSIs correspond to a plurality of TRPs, that is, the feedback of a plurality of CSIs in the MTRP CSI report can be well realized, thereby solving the problem in the prior art that the reporting efficiency of the reported CSI is poor because each CSI report arrangement corresponds to one TRP report, and improving the efficiency of reporting the CSI.

[0043] It should be noted that the uplink channels in the embodiments of the present application are preferably PUSCH and PUCCH. The following will interpret and explain the present application while associating the above two uplink channels.

[0044] In an alternative embodiment of the embodiments of the present application, when the uplink channel is the physical uplink shared channel PUSCH, the method of transmitting the MTRP CSI report to the MTRP based on the uplink channel related to S202 may include at least one of the following.

[0045] S202-11, Place all or some of the CSI in the MTRP CSI report on multiple PUSCH overlapping resources respectively and report to the MTRP. Here, different first parameters are arranged for each PUSCH overlapping resource, and one PUSCH corresponds to one first parameter.

[0046] In a specific application scenario, the network may arrange or activate PUSCH repetition resources with different spatial relation / power control parameters that have already been arranged, and place all or some of the CSI on multiple PUSCH repetition resources respectively and report to multiple TRP transmission points (on the network side). Here, each PUSCH corresponds to one TRP / spatial relation / power control parameter.

[0047] S202-12, Place all or some of the CSI in the MTRP CSI report on multiple PUSCH resources respectively and report to the MTRP. Here, one downlink control information triggers multiple PUSCH resources, and each PUSCH resource corresponds to one second parameter.

[0048] In a specific application scenario, one DCI may trigger multiple PUSCH resources, and all or some of the CSI may be carried on the multiple PUSCH resources respectively and reported to multiple TRPs. Here, each PUSCH corresponds to parameters such as information indicated by one TRP / spatial relation / SRI / power control / TPMI / MCS or other DCI domains, or one RRC configuration parameter.

[0049] It should be noted that the first parameter or the second parameter in the embodiments of the present application includes at least one of a spatial relation, power control, first information, second information, and a radio resource control RRC configuration parameter. Here, the first information includes at least one of a sounding reference signal resource indication SRI, a precoding matrix indication TPMI, and a modulation and coding policy MCS among the information indicated by the DCI domain in the DCI, and the second information includes information other than the first information among the information indicated by the DCI domain in the DCI.

[0050] In another alternative embodiment of the embodiments of the present application, when the uplink channel is a physical uplink control channel PUCCH, the method of transmitting an MTRP CSI report to the MTRP based on the uplink channel related to S202 includes at least one of the following.

[0051] S202-21, place all or some of the CSI in the MTRP CSI report on multiple PUCCH overlapping resources respectively and report to the MTRP. Here, different first parameters are arranged for each PUCCH overlapping resource, and one PUCCH corresponds to one first parameter.

[0052] In a specific application scenario, PUCCH repetitions with different spatial relations may be arranged or activated, and all or some of the CSI may be carried on a plurality of PUCCH repetition resources respectively and reported to a plurality of TRPs. Here, each PUCCH corresponds to one TRP / spatial relation / power control parameter.

[0053] S202-21, Place all or some of the CSI in the MTRP CSI report on a plurality of PUCCH resources respectively and report to the MTRP. Here, one CSI report setting is related to a plurality of PUCCH resources, and each PUCCH resource corresponds to one second parameter.

[0054] In a specific application scenario, one report may be related to a plurality of PUCCH resources, and each PUCCH resource corresponds to one TRP / spatial relation / power control parameter.

[0055] It should be noted that for PUSCH / PUCCH repetition resources with different spatial relations, CSI is mapped in different repetition resources, where the repetition resources include at least one of PUSCH repetition resources and PUCCH repetition resources.

[0056] Here, taking the case where the first repetition resource and the second repetition resource are different repetition resources as an example, there are the following two ways for the content included in the first repetition resource and the second repetition resource.

[0057] Method 1: The content on the first repetition resource includes at least one of uplink control information UCI corresponding to the first TRP and common part content, and the content on the second repetition resource includes at least one of UCI corresponding to the second TRP and common part content, or Method 2: The content on the first overlapping resource includes at least one of the UCI corresponding to the first TRP, the UCI corresponding to the second TRP, and the common part content. The content on the second overlapping resource includes at least one of the UCI corresponding to the first TRP, the UCI corresponding to the second TRP, and the common part content. Here, the common part content is a reporting parameter shared by the first TRP and the second TRP. The reporting parameter includes at least one of a channel state information reference signal resource indicator (CRI), a precoding matrix indicator (PMI), a rank indicator (RI), a channel quality indicator (CQI), a reference signal received power (RSRP), a composite codebook index i1, a synchronization signal block resource indicator (SSBRI), a signal-to-noise and interference ratio (SINR), and a layer indicator (LI).

[0058] In the following, taking the overlapping number being 4 as an example, the mapping relationship of the above CSI is exemplarily described. When the overlapping number is 4, the first and second overlapping resources may have different spatial relations, and both the first and second overlaps can be mapped to the corresponding CSI.
