Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the specific type of the terminal 11 in the embodiment of the present application is not limited.

[0018] First, relevant terms used in the practice of this application will be interpreted.

[0019] 1. Multi-TRP transmission technology 3GPP Rel-16 standardizes multi-transmission point / multi-antenna panel (multi-TRP / multi-panel) scenarios to improve transmission reliability and throughput performance, for example, a UE can receive the same or different data from multiple TRPs. Multi-TRPs can be divided into ideal backhaul and non-ideal backhaul. In a non-ideal backhaul, the interaction information between multi-TRPs has a relatively large delay and is suitable for relatively independent scheduling, and ACK / NACK and CSI reports are fed back to each TRP respectively. Generally, it is applied to multi-downlink control information (DCI) scheduling, i.e., each TRP transmits a respective physical downlink control channel (PDCCH), each PDCCH schedules a respective physical downlink shared channel (PDSCH), and multiple control resource sets (CORESETs) configured for a UE are associated with different Radio Resource Control (RRC) parameters CORESETPoolIndex and correspond to different TRPs. Multiple PDSCHs scheduled by multiple DCIs may not overlap, may overlap partially, or may overlap completely in time-frequency resources. In overlapping time-frequency resources, each TRP performs precoding independently based on its respective channel, and the UE receives multi-layer data streams belonging to multiple PDSCHs in the manner of non-coherent joint transmission (NCJT).

[0020] In an ideal backhaul line, scheduling information and UE feedback information can be interacted in real time between multiple TRPs. In addition to the above-mentioned multiple DCIs can be used to schedule multiple PDSCHs, PDSCHs can also be scheduled by a single DCI, including the following several transmission methods:

[0021] 1) Space Domain Scheduling (SDM): Different data layers of the same Transport Block (TB) 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 overlaps of different RVs of the same TB from different TRPs, eg overlaps within one slot, or overlaps across multiple slots.

[0022] In this case, the ACK / NACK feedback and the CSI report can be fed back to one of the TRPs.

[0023] II. CSI Report Configuration for 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 reporting (AP-CSI): transmitted only on PUSCH,

[0024] III. CSI reporting mechanism in Rel-16 based on PUSCH The PUSCH-based CSI report supports Type 1 wideband or subband CSI, and also supports Type 2 CSI.

[0025] For Type 1, Type 2 and reinforced Type 2 CSI feedback based on PUSCH, one CSI report consists of two parts (Part 1 and Part 2), where Part 1 has a certain load size and Part 2 has a certain number of information bits. It should be noted that Part 1 is transmitted in its entirety before Part 2.

[0026] For Type 1 CSI feedback, Part 1 includes one or more of RI (Rank Indicator), CRI (CSI-RS Resource Indicator, channel state information reference signal resource indication), and CQI of the first codeword, and Part 2 includes one or more of PMI and CQI of the second codeword.

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

[0028] For the augmented Type 2 CSI feedback, Part 1 includes RI, CQI, and an indication of the total number of non-zero amplitude coefficients between the augmented Type 2 CSI layers, and Type 2 includes a precoding matrix indicator (PMI) for the augmented Type 2 CSI.

[0029] When the CSI based on the PUSCH report includes Part 1 and Part 2, the UE may remove some Part 2 CSI content, where for the augmented Type 2 CSI report, Group 0 is the CSI with index i 1,1 , i 1,2 and i 1,8,l (l=1, …, v), and Group1 contains index i 1,5 (if reported), i 1,6,l , the part with high priority i 1,7,l , i 2,3,l , the part with high priority i 2,4,l , the part with high priority i 2,5,l (l=1, …, v), and Group2 is the low-priority part i 1,7,l , low priority part i 2,4,l , low priority part i 2,5,l (l=1, …, v), and the interpretation of the specific feedback amount is shown in Tables 1 and 2.

[0030] [Table 1]

[0031] [Table 2]

[0032] 4. CSI reporting mechanism in Rel-16 based on PUCCH Periodic CSI reporting based on PUCCH formats 2, 3, and 4 supports wideband Type 1 CSI. Semi-persistent CSI reporting based on PUCCH supports Type 1 CSI. Semi-persistent CSI reporting based on PUCCH format 2 supports wideband Type 1 CSI. Semi-persistent CSI reporting based on PUCCH format 3 or 4 supports wideband and subband Type 1 CSI and Type 2 CSI Part 1. When the subband Type 1 CSI is reported based on PUCCH format 3 or 4, the CSI load is divided into two parts (Part 1 and Part 2), where Part 1 includes RI, CRI, and some or all of the CQI corresponding to the first codeword, and Part 2 includes PMI and CQI corresponding to the second codeword (if RI > 4, there are two codewords); When one CSI report includes two parts, the UE may discard some of the Part 2 CSI content, and the priority ranking is consistent with the priority based on the PUSCH report.

[0033] 5. Potential CSI framework for multi-TRP In the current protocol, multi-TRP / multi-panel is specifically defined in terms of CSI report allocation, report content, CSI resource allocation, etc., and there are several specific methods as follows:

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

[0035] 2) The base station configures one CSI reporting setting and defaults or instructs that multiple CSI resource settings or multiple CSI resources are used in cooperation to calculate one CSI report. In particular, in the joint calculation of one CQI, in one CSI report, one PMI and / or RI can be obtained based on the CSI resource setting or CSI resource determined by the CRI, and one CQI (meaning of one CQI: according to conventional protocol definition, it may include wideband or subband CQI of one or two codewords) is determined individually or jointly based on these PMI / RI.

[0036] 3) The terminal feeds back to multiple TRPs that the CSI report includes CSI of a DPS corresponding to one TRP and indication information of another TRP to instruct another TRP not to schedule the terminal, and / or includes CSI corresponding to at least two TRPs, where each TRP fed back from the terminal corresponds to CSI of an NCJT.

[0037] 4) The network can be configured to determine which type of CSI the terminal reports or to report multiple types of CSI.

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

[0039] Hereinafter, 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 application scenarios thereof in conjunction with the drawings.

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

[0041] S202, sending a multi-transmission point channel state information (MTRP CSI) report to a multi-transmission point (MTRP) according to an uplink channel; Here, the MTRP CSI report contains multiple CSIs.

[0042] According to S202 in the embodiment of the present application, since the MTRP CSI report includes multiple CSI, by sending the MTRP CSI report to the MTRP, the multiple CSI corresponds to multiple TRPs, that is, the feedback of multiple CSI in the MTRP CSI report can be well realized, thereby solving the problem in the conventional technology that each CSI report configuration corresponds to one TRP report, resulting in poor reporting efficiency of the reported CSI, and improving the efficiency of the reported CSI.

[0043] It should be noted that the uplink channels in the embodiment of the present application are preferably PUSCH and PUCCH. The following description will be given by combining the above two uplink channels to explain the present application.

[0044] In an optional embodiment of the present application, when the uplink channel is a physical uplink channel shared channel PUSCH, the manner of sending an MTRP CSI report to the MTRP based on the uplink channel for S202 may include at least one of the following:

[0045] S202-11, all or part of the CSI in the MTRP CSI report is respectively carried on multiple PUSCH overlapping resources and reported to the MTRP, where each PUSCH overlapping resource is configured with a different first parameter, and one PUSCH corresponds to one first parameter.

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

[0047] S202-12: all or part of the CSI in the MTRP CSI report is respectively carried on a plurality of PUSCH resources and reported to the MTRP, where one downlink control information triggers a plurality of PUSCH resources, and each PUSCH resource corresponds to a second parameter.

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

[0049] It is to be noted that the first parameter or the second parameter in the embodiment of the present application includes at least one of a spatial relationship, a power control, a first information, a 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 excluding the first information among the information indicated by the DCI domain in the DCI.

[0050] In another optional embodiment of the embodiment of the present application, when the uplink channel is a physical uplink control channel PUCCH, the manner of sending an MTRP CSI report to the MTRP based on the uplink channel for S202 includes at least one of the following:

[0051] S202-21, all or part of the CSI in the MTRP CSI report is respectively carried on multiple PUCCH overlapping resources and reported to the MTRP, where each PUCCH overlapping resource is configured with a different first parameter, and one PUCCH corresponds to one first parameter.

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

[0053] S202-21, all or part of the CSI in the MTRP CSI report is respectively carried on multiple PUCCH resources and reported to the MTRP, where one CSI report setting is associated with multiple PUCCH resources, and each PUCCH resource corresponds to one second parameter.

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

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

[0056] Here, in the case where the first overlapping resource and the second overlapping resource are different overlapping resources, the contents included in the first overlapping resource and the second overlapping resource can be in the following two ways.

[0057] Method 1: The content on the first overlapping 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 overlapping 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 a UCI corresponding to the first TRP, a UCI corresponding to the second TRP, and a common part content, and the content on the second overlapping resource includes at least one of a UCI corresponding to the first TRP, a UCI corresponding to the second TRP, and a common part content; Here, the common part content is a reporting parameter shared by the first TRP and the second TRP, and the reporting parameter includes at least one of a channel state information reference signal resource indication CRI, a PMI, a rank indication RI, a channel quality indication CQI, a reference signal received power (Reference Signal Received Power, RSRP), a composite codebook index i1, a synchronization signal block resource indication (SSB Resource Indicator, SSBRI), a signal-to-noise and interference ratio (SINR), and a layer indication (Layer Indicator, LI).

[0058] In the following, the mapping relationship of the above CSI will be described by taking the example where the number of overlaps is 4. When the number of overlaps 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.

[0060] S21, partition the MTRP CSI report, where each type of parameter in the partitioned MTRP CSI report corresponds to one or more TRPs.

[0061] By the above S21, after dividing the MTRP CSI report, each type of parameter in the divided MTRP CSI report corresponds to one or multiple TRPs, thereby avoiding the problem of the conventional technology that the content contained in Part 1 and Part 2 of one CSI belongs to the CSI of one TRP and multiple CSIs of multiple TRPs cannot be supported.
