[0028] In order to better understand the technical solutions of the present application, the following is first introduced:

[0029] I. CSI report configuration

[0030] (1) If the report quantity (reportQuantity) field in the higher layer parameter CSI-ReportConfig is set to 'cri-RI-CQI', the terminal assumes that the PMI is an identity matrix, and only needs to report the channel state information reference signal resource index (CRI), the rank indicator (RI), and the channel quality indicator (CQI), without reporting the precoding matrix indicator (PMI), i.e., it can be understood that this CSI configuration is a non-codebook-based CSI reporting configuration.

[0031] (2) If the terminal is configured with the higher layer parameter non-PMI-PortIndication included in the CSI-ReportConfig, the non-PMI-PortIndication includes a port (port) indication sequence:

[0032]

[0033] wherein, is the CSI-RS port indication R ∈ {1, 2, …, P} for rank v, P ∈ {1, 2, 4, 8} representing the number of ports of the CSI-RS resource. At this time, the UE only reports the RI corresponding to the signaling PortIndexFor8Ranks.

[0034] (3) If the terminal is not configured with the higher layer parameter non-PMI-PortIndication, the UE assumes that the port indication of each CSI-RS resource is i.e., rank 1 corresponds to port 0, rank 2 corresponds to port 1, and so on, and rank v-1 corresponds to port v-1, where v = 1, 2, …, P, wherein P is the number of ports of the CSI-RS resource.

[0035] (4) The fields included in the CSI reporting configuration, as shown in Table 1:

[0036]

[0037]

[0038]

[0039] Table 1

[0040] II. CQI calculation

[0041] When the terminal calculates a rank value of CQI, the terminal uses the selected channel measurement resource to obtain the precoding matrix for the port indicated by the rank value, and the terminal assumes that the precoding matrix of the corresponding indicated port is a unit integer, and the power scaling factor is

[0042] III. CSI reporting

[0043] (1) PUSCH-based CSI reporting mechanism;

[0044] The CSI based on PUSCH reporting supports Type1 wideband or subband CSI, and also supports Type2 CSI.

[0045] For Type1, Type2 and enhanced Type2 CSI based on PUSCH feedback, a CSI report consists of two parts (Part1 and Part2), Part1 has a fixed load size, and at the same time indicates the number of information bits of Part2, note: Part1 must be transmitted before Part2.

[0046] For Type1 CSI feedback, Part1 includes one or more of RI, CRI, CQI of the first codeword, and Part2 contains one or more of PMI and CQI of the second codeword;

[0047] For Type2 CSI feedback, Part1 includes one or more of RI, CQI, and Type2 CSI per-layer non-zero wideband amplitude coefficient indication, and Part2 contains the PMI of Type2 CSI;

[0048] For enhanced Type2 CSI feedback, Part1 includes RI, CQI, and an indication of the total number of enhanced Type2 CSI cross-layer non-zero amplitude coefficients, and Type2 contains the PMI of enhanced Type2 CSI;

[0049] (2) PUCCH-based CSI reporting mechanism;

[0050] PUCCH format 2, 3, 4-based periodic CSI reporting supports wideband Type1 CSI;

[0051] PUCCH-based semi-persistent CSI reporting supports Type1 CSI;

[0052] PUCCH format 2-based semi-persistent CSI reporting supports wideband Type1 CSI;

[0053] The semi-persistent CSI reporting based on PUCCH format 3 or 4 supports wideband and subband Type 1 CSI and Type 2 CSI Part 1.

[0054] For the case of subband Type 1 CSI reporting based on PUCCH format 3 or 4, the CSI payload can be divided into two parts (Part 1 and Part 2), Part 1 includes RI, CRI, part or all of the CQI corresponding to the first codeword, and Part 2 includes PMI and the CQI corresponding to the second codeword (when RI>4, there are two codewords).

[0055] Four, CSI processing criteria

[0056] UE's capability of processing CSI reporting, i.e., the number of simultaneous CSI calculations supported N CPU that need to be reported to the network. If a UE supports N CPU simultaneous CSI calculations, it means that the UE has N CPU CSI processing units (CPU) for processing the CSI reports of all configured cells.

[0057] The number of available CPUs: in a certain OFDM symbol, if there are L CPUs already occupied for processing CSI reports, the UE has N CPU -L available CPUs. If there are N CSI reports to start occupying CPUs in this OFDM symbol, the n=0, …, N-1 CSI reports need to occupy CPUs, and there is a possibility that the number of available CPUs is less than the number of CPUs that N CSI reports need to occupy, then the UE does not need to update N-M low-priority CSI reports, where 0≤M≤N is the maximum value that satisfies .

[0058] The number of CPUs occupied by the CSI report, as shown in Table 2:

[0059]

[0060]

[0061] Table 2

[0062] K s is the number of CSI-RS resources included in the CSI-RS resource set for channel measurement.

[0063] Five, MTRP transmission scheme

[0064] Multi-TRP / multi-panel scenarios can increase the reliability and throughput performance of transmission, for example, a UE can receive the same data or different data from multiple TRPs. Multi-TRPs can be divided into ideal backhaul and non-ideal backhaul. When the backhaul is non-ideal, there is a large delay in the exchange of information between multi-TRPs, and independent scheduling is more suitable, and ACK / NACK and CSI reporting are fed back to each TRP. It is usually applicable to multi-DCI scheduling, that is, each TRP sends its own PDCCH, each PDCCH schedules its own PDSCH, and multiple CORESETs configured for the UE are associated with different RRC parameters CORESETPoolIndex, corresponding to different TRPs. Multiple PDSCHs scheduled by multiple DCIs can be non-overlapping, partially overlapping, or completely overlapping in time and frequency resources. On the overlapping time and frequency resources, each TRP independently precodes according to its own channel, and the UE receives multiple layer data streams belonging to multiple PDSCHs in a non-coherent joint transmission (NCJT) manner.

[0065] When the backhaul is ideal, multi-TRPs can exchange scheduling information and UE feedback information in real time. In addition to the above multi-DCI scheduling of multiple PDSCHs, single-DCI scheduling of PDSCHs is also possible, including some transmission schemes as follows:

[0066] Space Division Multiplexing (SDM): different data layers of the same TB are NCJT transmitted from different TRPs;

[0067] Frequency Division Multiplexing (FDM): different frequency domain resources of the same TB mapped with the same RV are transmitted from different TRPs, or different RVs of the same TB are mapped to different frequency domain resources and transmitted from different TRPs;

[0068] Time Division Multiplexing (TDM): multiple repetitions of different redundancy versions (RVs) of the same TB are from different TRPs, for example, repetitions in a time slot or repetitions in multiple time slots.

[0069] At this time, ACK / NACK feedback and CSI reporting can be fed back to any TRP.

[0070] The multi-TRP / multi-panel CSI reporting configuration, reporting content, and CSI resource configuration will be defined in detail. The following methods are mainly included:

[0071] (1) Configure 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 reporting of one TRP.

[0072] (2) The base station configures one CSI reporting setting, and indicates that one CSI report is jointly (collectively) calculated by multiple CSI resources by default.

[0073] The method and device provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings, specific embodiments, and application scenarios.

[0074] Referring to Figure 2 , the present application provides a non-codebook CSI acquisition method, and the execution subject of the method can be a terminal, and the specific steps include:

[0075] Step 201: The terminal acquires a CSI reporting configuration; specifically, the CSI reporting configuration is a non-codebook-based CSI reporting configuration.

[0076] As a possible implementation manner, the CSI reporting configuration is issued by the base station to the terminal.

[0077] Step 202: The terminal determines the measurement port of the CMR according to the association relationship and the rank value obtained according to the CSI reporting configuration; wherein the association relationship is the association relationship between the rank value and the measurement port of the CMR, and the measurement port of the CMR refers to the port for measuring the CMR.

[0078] Step 203: The terminal obtains the non-codebook CSI according to the measurement port of the CMR.

[0079] The channel measurement resource (CMR) includes a CMR for MTRP measurement assumption, that is, the method can be applied to a scenario with only MTRP transmission, and the subsequent CSI report includes only CSI of the MTRP measurement assumption, or the CMR includes a CMR for MTRP measurement assumption and a CMR for STRP measurement assumption, that is, the method can also be applied to a scenario with STRP transmission and MTRP transmission, and the subsequent CSI report includes CSI of the MTRP measurement assumption and CSI of the STRP measurement assumption, or the method can also be applied to a scenario with STRP transmission or MTRP transmission, and the subsequent CSI report can include CSI of one of the MTRP measurement assumption and the STRP measurement assumption.

[0080] It should be noted that the rank value can also be referred to as a rank indication or RI, and the CMR can also be referred to as a CSI-RS resource.

[0081] It can be understood that after the association between the rank value and the measurement port of the CMR is known, the terminal can measure or obtain the measurement result of the related port based on each rank value in the associated measurement port, and then complete the CSI acquisition.

[0082] In the embodiments of the present application, the measurement port of the CMR is determined according to the association between the rank value and the measurement port of the CMR, and the rank value obtained through the CSI report configuration, so that the CSI acquisition in the scenario of considering STRP transmission and MTRP transmission at the same time can be realized, and independent configuration of each measurement assumption can be realized.

[0083] It should be noted that for the case where the CMR includes a CMR for MTRP measurement assumption and a CMR for STRP measurement assumption, it can be further divided into a case where the CMR for MTRP measurement assumption and the CMR for STRP measurement assumption are not shared, and a case where the CMR for MTRP measurement assumption and the CMR for STRP measurement assumption are shared, and the specific CMR sharing or not sharing can be configured or indicated through high-layer signaling of the network side, or a pre-set rule is used to determine whether the CMR is shared or not shared.

[0084] In one possible implementation, the case where the CMR for MTRP measurement assumption and the CMR for STRP measurement assumption are not shared includes:

[0085] The terminal does not expect the CMR for the MTRP measurement hypothesis and the CMR for the STRP measurement hypothesis to be shared, that is, the terminal does not expect the network to configure or activate a non-codebook-based CSI report configuration while indicating that the UE MTRP measurement hypothesis and the STRP measurement hypothesis share the CMR.

[0086] Alternatively, the terminal assumes that the CMR for the MTRP measurement hypothesis and the CMR for the STRP measurement hypothesis are not shared.

[0087] The above association relationship can be a pre-set default association relationship, or the above association relationship can also be an association relationship indicated by information carried in the CSI report configuration.

[0088] In a possible implementation, the CSI report configuration does not include a port indication field for indicating the association relationship, and at this time, the association relationship between the rank value and the measurement ports of the CMR can be a pre-set default association relationship, so that the terminal can directly determine the association relationship between the rank value and the measurement ports of the CMR through the default rule.

[0089] The association relationship includes one or more of the following:

[0090] (1) In the case where the CMR includes the CMR for the MTRP measurement hypothesis, the association relationship includes: an association relationship between a rank value V and the first V measurement ports or the last V measurement ports in a port sequence of the CMR, the port sequence being a sequence of N measurement ports of the CMR, N being greater than or equal to V, and N and V being positive integers.

[0091] In the embodiments of the present application, when the network high-layer signaling indicates or the high-layer signaling configures the CSI report to include only the CSI of the MTRP measurement hypothesis, the terminal assumes that the first V ports of each CMR correspond to rank V.

[0092] It should be noted that in actual application scenarios, the V ports corresponding to the rank V can not be the first V ports or the last V ports of the CMR, but can be V ports at a pre-set position in the port sequence of the CMR.

[0093] For example: Assuming that the CMR is configured with a 4-port resource, the port sequence is {3000, 3001, 3002, 3003} (this scenario is used in subsequent examples), then the first 2 ports {3000, 3001} of the CMR correspond to a rank value of rank 2, and the first 3 ports {3000, 3001, 3003} correspond to a rank value of rank 3.

[0094] (2) in the case that the CMRs include CMRs for MTRP measurement assumption and CMRs for STRP measurement assumption, and the CMRs for MTRP measurement assumption and the CMRs for STRP measurement assumption do not share, the association relationship includes: an association relationship between a rank value V and the first V measurement ports or the last V measurement ports in a port sequence of a CMR, the port sequence being a sequence of N measurement ports of the CMR, N being greater than or equal to V, and N and V being positive integers;

[0095] In the embodiment of the application, when the network higher layer signaling indicates or the higher layer signaling configures that the MTRP and the STRP measurement assumption do not share the CMR, the terminal assumes that the first V ports of each CMR correspond to rank V. It can be understood that the rank V can also correspond to the V ports of a preset position of the CMR.

[0096] For example: the first 2 ports {3000, 3001} of the CMR correspond to a rank value of rank 2, and the first 3 ports {3000, 3001, 3003} correspond to a rank value of rank 3.

[0097] (3) in the case that the CMRs include CMRs for MTRP measurement assumption and CMRs for STRP measurement assumption, and the CMRs for MTRP measurement assumption and the CMRs for STRP measurement assumption share, the association relationship includes: an association relationship between a rank value R of the MTRP measurement assumption and R measurement ports in a port sequence of the shared CMR, and an association relationship between a rank value V of the STRP measurement assumption and V measurement ports in the port sequence of the shared CMR, the port sequence being a sequence of N measurement ports of the shared CMR, N being greater than R, N being greater than V, and N, R and V being positive integers.

[0098] In the embodiment of the application, since the CMRs share, a part of the ports of the shared CMR is used for the MTRP measurement assumption, and a part of the ports of the shared CMR is used for the STRP measurement assumption.

[0099] Further, the association relationship between the rank value R of the MTRP measurement assumption and the R measurement ports in the port sequence of the shared CMR, and the association relationship between the rank value V of the STRP measurement assumption and the V measurement ports in the port sequence of the shared CMR include any one of the following:

[0100] (3.1) the association relationship between the rank value R of the MTRP measurement assumption and the first R measurement ports or the last R measurement ports in the port sequence of the shared CMR, and the association relationship between the rank value V of the STRP measurement assumption and the remaining V measurement ports other than the first R measurement ports or the last R measurement ports in the port sequence of the shared CMR;

[0101] In the embodiments of the present application, when the network higher layer signaling indicates or configures that the MTRP and STRP measurement assumptions share a certain or certain CMR, the first R ports or the last R ports corresponding to the shared CMR correspond to the MTRP measurement assumption, and the remaining ports indicate that they correspond to the STRP measurement assumption. It can be understood that the rank R can also correspond to the R ports in the preset position of the CMR.

[0102] For example: the first two ports of the shared CMR correspond to the MTRP measurement assumption, that is, the ports {3000, 3001} correspond to the MTRP measurement assumption, and the remaining two ports correspond to the STRP measurement assumption, that is, {3002, 3003} correspond to the STRP measurement assumption.

[0103] (3.2) The association relationship between the rank value R of the MTRP measurement assumption and the first R measurement ports or the last R measurement ports in the port sequence of the shared CMR, and the association relationship between the rank value V of the STRP measurement assumption and the first V measurement ports or the last V measurement ports in the port sequence of the shared CMR. It can be understood that the rank V can also correspond to the V ports in the preset position of the CMR, and the rank R can also correspond to the R ports in the preset position of the CMR.

[0104] In the embodiments of the present application, when the network higher layer signaling indicates or configures that the MTRP and STRP measurement assumptions share a certain or certain CMR, the first R ports corresponding to the shared CMR correspond to the MTRP measurement assumption, and the last V ports correspond to the STRP measurement assumption, and vice versa.

[0105] For example: the first two ports of the shared CMR correspond to the MTRP measurement assumption, that is, the ports {3000, 3001} correspond to the MTRP measurement assumption, and the last three ports correspond to the STRP measurement assumption, that is, {3001, 3002, 3003} correspond to the STRP measurement assumption.

[0106] Or, the first R ports corresponding to the shared CMR correspond to the MTRP measurement assumption, and the first V ports correspond to the STRP measurement assumption, and vice versa.

[0107] For example: the first two ports of the shared CMR correspond to the MTRP measurement assumption, that is, the ports {3000, 3001} correspond to the MTRP measurement assumption, and the first three ports correspond to the STRP measurement assumption, that is, {3000, 3001, 3002} correspond to the STRP measurement assumption.

[0108] In a possible implementation, the association relationship is indicated by the port indication field included in the CSI report configuration.

[0109] In the embodiments of the present application, the association relationship between the rank value and the measurement port of the CMR is carried in the CSI report configuration, specifically, the association relationship is indicated by a port indication field in the CSI report configuration. In this way, the terminal can determine the association relationship between the rank value and the measurement port of the CMR according to the indication content of the port indication field.

[0110] Further, the port indication field includes one or more entries, and each entry includes X indication values arranged in a preset order. The indication values in the one or more entries indicate the association relationship between the measurement port of the CMR of the MTRP measurement hypothesis and the rank value, or the indication values in the one or more entries indicate the association relationship between the measurement port of the CMR of the MTRP and STRP measurement hypotheses and the rank value. In this way, the terminal can determine the measurement port of the CMR associated with each rank value in the CSI acquisition process according to the indication values arranged in the preset order in the entry corresponding to the MTRP measurement hypothesis or the entry corresponding to the STRP measurement hypothesis.

[0111] The X is associated with the number of measurement ports of the CMR of the MTRP measurement hypothesis or the number of measurement ports of the CMR of the STRP measurement hypothesis. For example, if the CMR is configured as 4 ports, the value of X is 4. Alternatively, the X is associated with a preset rank value of the MTRP measurement hypothesis or a preset rank value of the STRP measurement hypothesis. The preset rank value can be a preset upper limit of the rank value. For example, for the STRP measurement hypothesis, if the preset rank value is 4, it means that the measurements of rank 1, rank 2, rank 3 and rank 4 are needed. For the MTRP measurement hypothesis (assuming that the MTRP includes TRP1 and TRP2), if the preset rank value is 4, it means that the measurements of rank 1 and rank 2 of TRP1 and the measurements of rank 1 and rank 2 of TRP2 are needed.

[0112] The following describes various cases of determining the association relationship based on the port indication field:

[0113] In a possible implementation, when the CMR includes the CMR for the MTRP measurement hypothesis, the CSI report configuration includes one port indication field, that is, for the scenario of only MTRP transmission, there is only one port indication field in the CSI report configuration.

[0114] The association relationship includes one or more of the following:

[0115] (1) the port indication field includes B entries, and an Nth entry in the B entries indicates an association relationship between a measurement port and a rank value of one or more CMRs of an Nth MTRP measurement hypothesis in the B MTRP measurement hypotheses, N is not greater than B, and N and B are positive integers;

[0116] In the embodiments of the present application, when the network higher layer signaling indicates or the higher layer signaling configures the CSI report to contain only MTRP measurement hypotheses, and the report setting includes one port indication field, the first entry of the field corresponds to the CMR / CMRs of the 1st MTRP measurement hypothesis, and the Nth entry corresponds to the CMR / CMRs of the Nth MTRP measurement hypothesis.

[0117] For example, assuming that the result of the CMR configuration is that the CMRs of the MTRP measurement hypothesis are CMR1 and CMR2, the first entry of the indication field indicates the port and rank relationship of CMR1 and CMR2. The indication mode of the first entry can be that the former part of the indication value corresponds to the port and rank relationship of CMR1, and the latter part of the indication value corresponds to the port and rank relationship of CMR2, or the first entry can be split into multiple indication values, and each indication value corresponds to a rank combination and the port relationship of CMR1 and CMR2. It should be noted that in this example scenario, only one entry corresponding to the MTRP measurement hypothesis is taken as an example for description, and therefore there is only one entry corresponding to the MTRP measurement hypothesis. For a scenario with multiple MTRP transmission measurement hypotheses, for example, there are two MTRP transmission measurement hypotheses, and therefore there are two entries corresponding to the two MTRP transmission measurement hypotheses. The subsequent example scenarios follow the example of only one MTRP transmission measurement hypothesis.

[0118] (2) the port indication field includes B·K entries, and (N-1)·K+1th to N·Kth entries in the B·K entries indicate an association relationship between a measurement port and a rank value of one or more CMRs of an Nth MTRP measurement hypothesis in the B MTRP measurement hypotheses, K is the number of CMRs required by one MTRP measurement hypothesis, N is not greater than B, and N, K and B are positive integers.

[0119] In the embodiments of the present application, when the network higher layer signaling indicates or the higher layer signaling configures the CSI report to contain only MTRP measurement hypotheses, and the report setting includes one port indication field, the 1st to Kth entries correspond to the CMRs of the 1st MTRP measurement hypothesis, and the (N-1)·K+1th to N·Kth entries correspond to the CMRs of the Nth MTRP measurement hypothesis, where K represents the number of CMRs required by the MTRP measurement hypothesis.

[0120] For example, assuming that the result of the CMR configuration is to measure the MTRP measurement hypothesis, the CMR for the measurement hypothesis is: CMR1, CMR2; the first entry of the indication field indicates the port and rank relationship of CMR1, and the second entry indicates the port and rank relationship of CMR2.

[0121] In a possible implementation, in the case where the CMR includes the CMR for the MTRP measurement hypothesis and the CMR for the STRP measurement hypothesis, and the CMR for the MTRP measurement hypothesis and the CMR for the STRP measurement hypothesis do not share, one or two port indication fields are included in the CSI report configuration, that is, for the scene with STRP and MTRP transmission, one or two port indication fields can exist in the CSI report configuration.

[0122] The association relationship includes one or more of the following:

[0123] (1) In the case where one port indication field is included in the CSI report configuration, A first entries and B second entries are included in the port indication field, the Mth entry of the A first entries indicates the association relationship between the measurement port and the rank value of the CMR of the Mth STRP measurement hypothesis in the A STRP measurement hypotheses, the Nth entry of the B second entries indicates the association relationship between the measurement port and the rank value of the CMR of the Nth MTRP measurement hypothesis in the B MTRP measurement hypotheses, M is not greater than A, N is not greater than B, M, N, A, and B are positive integers.

[0124] In the embodiment of the application, when one port indication field is included, the first entry of the field corresponds to the CMR of the first STRP measurement hypothesis, the second entry corresponds to the CMR of the second STRP measurement hypothesis, and so on, the Mth entry corresponds to the CMR of the Mth STRP measurement hypothesis, the M+1th entry corresponds to the CMR of the 1st MTRP measurement hypothesis, and the M+Nth entry corresponds to the CMR of the Nth MTRP measurement hypothesis. That is, the indication field has M+N entries; it should be noted that, for the convenience of understanding, the first M entries in all entries correspond to the STRP measurement hypothesis, and the last N entries correspond to the MTRP measurement hypothesis, and it can be understood that, in the actual application process, the entries corresponding to the STRP measurement hypothesis and the entries corresponding to the MTRP measurement hypothesis can also not be arranged in order, as long as M entries correspond to the STRP measurement hypothesis and N entries correspond to the MTRP measurement hypothesis.

[0125] For example, assuming that the result of the CMR configuration is that the CMRs of the STRP measurement hypothesis are CMR1 and CMR2, and the CMRs of the MTRP measurement hypothesis are CMR3 and CMR4, the first entry of the indication field indicates the port and rank relationship of CMR1, the second entry indicates the port and rank relationship of CMR2, and the third entry indicates the port and rank relationship of CMR3 and CMR4, that is, the first two entries correspond to the STRP measurement hypothesis, and the third entry corresponds to the MTRP measurement hypothesis. As to the indication mode of the third entry, the former half of the indication value can indicate the port and rank relationship of CMR3, and the latter half of the indication value can indicate the port and rank relationship of CMR4, or the third entry can be split into multiple indication values, and each indication value corresponds to a rank combination and the port relationship of CMR3 and CMR4.

[0126] (2) In the case where one port indication field is included in the CSI report configuration, A first entries and B·K second entries are included in the port indication field, the Mth entry of the A first entries indicates the association relationship between the measurement port and the rank value of the CMR of the Mth STRP measurement hypothesis of the A STRP measurement hypotheses, and the terminal determines the association relationship between the measurement port and the rank value of the CMR of the Nth MTRP measurement hypothesis of the B MTRP measurement hypotheses according to the (N-1)·K+1th to N·Kth entries of the B·K second entries, M is not greater than A, N is not greater than B, K is the number of CMRs required by one MTRP measurement hypothesis, and M, N, A, B and K are positive integers.

[0127] In the embodiment of the present application, when one port indication field is included, the first entry of the field corresponds to the CMR of the first STRP measurement hypothesis, the second entry corresponds to the CMR of the second STRP measurement hypothesis, and so on, the Mth entry corresponds to the CMR of the Mth STRP measurement hypothesis, the (M+1)th to (M+K)th entries correspond to the CMRs of the 1st MTRP transmission measurement hypothesis, and the (M+(N-1)·K+1)th to (M+N·K)th entries correspond to the CMRs of the Nth MTRP transmission measurement hypothesis, where K represents the number of CMRs required by the MTRP transmission measurement hypothesis.

[0128] For example, assuming that the result of the CMR configuration is that the CMRs of the STRP measurement hypothesis are CMR1 and CMR2, and the CMRs of the MTRP measurement hypothesis are CMR3 and CMR4, the first entry of the indication field indicates the port and rank relationship of CMR1, the second entry indicates the port and rank relationship of CMR2, and the third entry indicates the port and rank relationship of CMR3. The fourth entry indicates the port and rank relationship of CMR4.

[0129] (3) in the case that the CSI reporting configuration includes one first port indication field and one second port indication field, the first port indication field includes A first entries, the second port indication field includes B second entries, the Mth entry in the A first entries indicates the association relationship between the measurement port and the rank value of the CMR of the Mth STRP measurement hypothesis in the A STRPs, the Nth entry in the B second entries indicates the association relationship between the measurement port and the rank value of the CMR of the Nth MTRP measurement hypothesis in the B MTRPs, M is not greater than A, N is not greater than B, M, N, A and B are positive integers;

[0130] (4) in the case that the CSI reporting configuration includes one first port indication field and one second port indication field, the first port indication field includes A first entries, the second port indication field includes B·K second entries, the Mth entry in the A first entries indicates the association relationship between the measurement port and the rank value of the CMR of the Mth STRP measurement hypothesis in the A STRPs, the (N-1)·K+1th to N·Kth entries in the B·K second entries indicate the association relationship between the measurement port and the rank value of the CMR of the Nth MTRP measurement hypothesis in the B MTRPs, K is the number of CMRs required for one MTRP measurement hypothesis, M is not greater than A, N is not greater than B, K is the number of CMRs required for one MTRP measurement hypothesis, M, N, A, B and K are positive integers;

[0131] In the embodiments of the present application, (3) and (4) above are the same as (1) and (2), when two port indication fields are included, one port indication field is used to indicate the corresponding relationship between the rank value of the CMR of the STRP measurement hypothesis and the port, and the other port indication field is used to indicate the corresponding relationship between the rank value of the CMR of the MTRP measurement hypothesis and the port.

[0132] Wherein the first entry of one port indication field corresponds to the CMR (channel measurement resource) of the first STRP measurement hypothesis, the second entry corresponds to the CMR of the second STRP measurement hypothesis, and so on, the Mth entry corresponds to the CMR of the Mth STRP measurement hypothesis;

[0133] The first entry of the other port indication field corresponds to the CMR of the first MTRP transmission measurement hypothesis, and the Nth entry corresponds to the CMR of the Nth MTRP transmission measurement hypothesis. Or the (N-1)·K+1th to N·Kth entries of the other port indication field correspond to the CMR of the Nth MTRP transmission measurement hypothesis, wherein K represents the number of CMRs required for the MTRP transmission measurement hypothesis;

[0134] In a possible implementation, in a case where the CMR includes CMRs for MTRP measurement assumption and CMRs for STRP measurement assumption, and the CMRs for MTRP measurement assumption and the CMRs for STRP measurement assumption are shared, one or two port indication fields are included in the CSI report configuration; that is, in a case where there is STRP and MTRP transmission, one or two port indication fields can exist in the CSI report configuration;

[0135] The association relationship includes one or more of the following:

[0136] (1) In a case where one port indication field is included in the CSI report configuration, Ks entries are included in the port indication field, each of the Ks entries indicates an association relationship between a measurement port of one CMR and a rank value, a first part of target entries in the Ks entries that indicate shared CMRs indicates an association relationship between a measurement port of a CMR of STRP measurement assumption and a rank value, a second part of target entries in the Ks entries that indicate shared CMRs indicates an association relationship between a port of a CMR of MTRP measurement assumption and a rank value, and Ks is a positive integer;

[0137] In the embodiment of the application, one port indication field is included, a first entry of the field corresponds to a first CMR, a second entry corresponds to a second CMR, and so on, and a Ks-th entry corresponds to a Ks-th CMR, where Ks is the number of CMRs of one channel measurement resource set. When the network higher layer signaling indicates or the higher layer signaling configures MTRP and STRP measurement assumption to share a certain or certain CMR, a part of indication values of the entry corresponding to the shared CMR correspond to the correspondence between the rank and the port when the MTRP measurement assumption, and a part of indication values correspond to the correspondence between the rank and the port when the STRP measurement assumption. Optionally, the former half of the indication values can correspond to the correspondence between the rank and the port when the MTRP measurement assumption, and the latter half of the indication values can correspond to the correspondence between the rank and the port when the STRP measurement assumption.

[0138] For example, assuming that the result of the CMR configuration is to configure 3 CMRs for measurement (CMR1, CMR2, CMR3), wherein the CMRs assumed by the measurement STRP measurement hypothesis are CMR1 and CMR2, and the CMRs assumed by the measurement MTRP measurement hypothesis are CMR2 and CMR3, the first entry of the port indication field indicates the relationship between the port and the rank of CMR1, the second entry indicates the relationship between the port and the rank of CMR2, and the third entry indicates the relationship between the port and the rank of CMR3. Since CMR2 is indicated as a CMR shared by the MTRP and the STRP, the second entry includes two indication values, the first indication value indicates the corresponding relationship between the rank and the port when the MTRP measurement hypothesis is assumed, and the second indication value indicates the corresponding relationship between the rank and the port when the STRP measurement hypothesis is assumed.

[0139] (2) In the case where one port indication field is included in the CSI report configuration, A first entries and S second entries are included in the port indication field, the Mth entry of the A first entries indicates the association relationship between the measurement port and the rank value of the CMR of the Mth STRP measurement hypothesis of the A STRP measurement hypotheses; each of the S second entries indicates the association relationship between the measurement port and the rank value of a CMR not shared by a MTRP measurement hypothesis, the Tth entry of the S second entries indicates the association relationship between the measurement port and the rank value of the Tth CMR not shared by the MTRP measurement hypothesis, M is not greater than A, T is not greater than S, and A, M, S, and T are positive integers;

[0140] In the embodiment of the present application, when one port indication field is included and the network high layer signaling indicates or the high layer signaling configures that the MTRP and the STRP measurement hypothesis share a certain or certain CMRs, the first entry of the field corresponds to the CMR of the first STRP measurement hypothesis, the second entry corresponds to the CMR of the second STRP measurement hypothesis, and so on, the Mth entry corresponds to the CMR of the Mth STRP measurement hypothesis, the M+1th entry corresponds to the 1st non-shared CMR, and the M+Sth entry corresponds to the Sth non-shared CMR. That is, the indication field has M+S entries, wherein the M+1th entry to the M+Sth entry only act on the non-shared CMRs of the MTRP measurement hypothesis, and for the shared CMRs, the entries corresponding to the corresponding STRP measurement hypothesis CMRs are used;

[0141] For example, assuming the result of CMR configuration is to configure 3 CMRs for measurement (CMR1, CMR2, CMR3), wherein the CMRs assumed by STRP measurement assumption are: CMR1, CMR2; the CMRs assumed by MTRP measurement assumption are: CMR2, CMR3; the first entry of the indication field indicates the port and rank relationship of CMR1, the second entry indicates the port and rank relationship of CMR2, and the third entry indicates the port and rank relationship of CMR3. CMR2 is a CMR shared by MTRP and STRP, so the entry of CMR2 is used for both STRP measurement assumption and MTRP measurement assumption;

[0142] (3) In the case of including one port indication field in the CSI report configuration, Ks first entries and S second entries are included in the port indication field, each of the Ks first entries respectively indicates the association relationship between the measurement port and the rank value of one CMR, each of the S second entries respectively indicates the association relationship between the measurement port and the rank value of one CMR shared by one MTRP measurement assumption, the Tth entry of the S second entries indicates the association relationship between the measurement port and the rank value of the Tth CMR shared by the MTRP measurement assumption, T is not greater than S, Ks, S and T are positive integers;

[0143] In the embodiment of the present application, when one port indication field is included and the network high layer signaling indicates or the high layer signaling configures MTRP and STRP measurement assumption to share some or some CMRs, the first entry of the field corresponds to the first CMR, the second entry corresponds to the second CMR, and so on, the Ks entry corresponds to the Ks CMR, wherein Ks is the number of CMRs of one channel measurement resource set. The Ks+1 entry corresponds to the 1st shared CMR, and the Ks+S entry corresponds to the Sth shared CMR. That is, there are Ks+S entries in the indication field, wherein the Ks+1 entry to the Ks+S entry only acts on the shared CMR of the MTRP measurement assumption, and for the non-shared CMR, the entry corresponding to the corresponding CMR is used;

[0144] For example, assuming the result of CMR configuration is to configure 3 CMRs for measurement (CMR1, CMR2, CMR3), wherein the CMRs assumed by STRP measurement assumption are: CMR1, CMR2; the CMRs assumed by MTRP measurement assumption are: CMR2, CMR3; the first entry of the indication field indicates the port and rank relationship of CMR1, the second entry indicates the port and rank relationship of CMR2, and the third entry indicates the port and rank relationship of CMR3. CMR2 is a CMR shared by MTRP and STRP, so the entry of CMR2 is used for both STRP measurement assumption and MTRP measurement assumption;

[0145] (4) In the case that the CSI reporting configuration includes one first port indication field and one second port indication field, the first port indication field includes A first entries, the second port indication field includes S second entries, the Mth entry of the A first entries indicates the association between the measurement port and rank value of the Mth STRP measurement hypothesis assumed CMR of the Mth STRP of the A STRPs; each of the S second entries respectively indicates the association between the measurement port and rank value of one MTRP measurement hypothesis unshared CMR, the Tth entry of the S second entries indicates the association between the measurement port and rank value of the Tth MTRP measurement hypothesis unshared Tth CMR, T is not greater than S, A, S and T are positive integers.

[0146] In the embodiments of the present application, when 2 port indication fields are included and the network high layer signaling indicates or configures that the MTRP and STRP measurement hypotheses share one or more CMRs, the first port indication field is used to indicate the association between the rank value and port of each CMR in the CMR set, and the second port indication field is used to indicate the association between the rank value and port of the shared CMR corresponding to the MTRP measurement hypothesis. For specific examples, reference can be made to the examples of (2) above, and the difference is that the present method indicates the association between the measurement port and rank value of the shared CMR through the second port indication field.

[0147] (5) In the case that the CSI reporting configuration includes one first port indication field and one second port indication field, the first port indication field includes Ks first entries, the second port indication field includes S second entries, each of the Ks first entries respectively indicates the association between the measurement port and rank value of one CMR, each of the S second entries respectively indicates the association between the measurement port and rank value of one MTRP measurement hypothesis shared CMR, the Tth entry of the S second entries indicates the association between the measurement port and rank value of the Tth MTRP measurement hypothesis shared Tth CMR, T is not greater than S, Ks, S and T are positive integers.

[0148] In the embodiments of the present application, when 2 port indication fields are included and the network high layer signaling indicates or configures that the MTRP and STRP measurement hypotheses share one or more CMRs, the first port indication field is used to indicate the association between the rank value and port of each CMR in the CMR set, and the second port indication field is used to indicate the association between the rank value and port of the shared CMR corresponding to the MTRP measurement hypothesis. For specific examples, reference can be made to the examples of (2) above, and the difference is that the present method indicates the association between the measurement port and rank value of the shared CMR through the second port indication field.

[0149] In a possible implementation, the terminal obtains the non-codebook CSI according to the measurement ports of the CMRs, including:

[0150] In the case that the terminal measures the CQI for each MTRP measurement hypothesis, the terminal determines that the channel precoding matrix is a unit matrix, and the scaling factor is 1 / sqrt(V1+V2+…+V K );

[0151] wherein K is the number of CMRs required for one MTRP measurement hypothesis, and V K is the rank value or the number of measurement ports of the Kth CMR used to calculate the MTRP measurement hypothesis.

[0152] In a possible implementation, the terminal obtains the CSI according to the measurement ports of the CMRs, including:

[0153] The terminal determines the number of CPUs;

[0154] The terminal calculates the non-codebook CSI by determining the number of CPUs;

[0155] wherein in the case that the CMRs include CMRs for MTRP measurement hypotheses, one MTRP measurement hypothesis corresponds to one CPU; in the case that the CMRs include CMRs for MTRP measurement hypotheses and CMRs for STRP measurement hypotheses, one MTRP measurement hypothesis corresponds to one CPU, and one STRP measurement hypothesis corresponds to one CPU.

[0156] For example, Ks CMRs are configured, wherein 2·N CMRs are used to measure N MTRP measurement hypotheses, and K CMRs are used to measure K STRP measurement hypotheses, and the calculation of the non-codebook CSI occupies K+N CPUs in total.

[0157] In addition, due to the limitation of the number of CPUs, the number of Ks needs to be limited: when the STRP measurement hypotheses share the CMRs with the MTRP measurement hypotheses, the calculation of one MTRP CSI report needs to satisfy that 2N+Ks or N+Ks is less than or equal to the maximum number of CPUs; when the STRP measurement hypotheses do not share the CMRs with the MTRP measurement hypotheses, the codebook-based CSI calculation needs to satisfy that Ks is less than or equal to the maximum number of CPUs, and this method is also applicable to the calculation of one MTRP CSI report based on the codebook.

[0158] In a possible implementation, the method further includes:

[0159] The terminal generates a CSI report according to the non-codebook CSI, and the CSI report does not include the CQI of the second codeword. The terminal achieves that the rank value does not exceed 4 in the CSI acquisition process by not expecting the CSI report to include the CQI of the second codeword.

[0160] In the embodiment of the application, the UE does not expect the network to configure a non-codebook-based MTRP CSI reporting configuration containing two parts, specifically, the terminal maps one or more of the following: one or more rank values, one or more channel state information reference signal resource indications CRI, CQI of one or more first codewords, and the terminal does not expect to map one or more of PMI and CQI of the second codeword.

[0161] The technical solutions of the application will be described below in combination with specific application embodiments:

[0162] Embodiment one:

[0163] In this embodiment, the CMR configuration is as shown in Table 3-1:

[0164]

[0165]

[0166] Table 3-1

[0167] That is, in this embodiment, the measurement resources are all configured as 4-port resources.

[0168] In this embodiment, the MTRP transmission is specifically the transmission of two TRPs, which can be denoted as TRP1 and TRP2.

[0169] This embodiment includes the following cases:

[0170] Case 1: In which CSI-RS resource 0 and CSI-RS resource 1 are used to measure the MTRP measurement assumption, and CSI-RS resource 2 and CSI-RS resource 3 are used to measure the STRP measurement assumption

[0171] Case 2: In which CSI-RS resource 0 and CSI-RS resource 1 are used to measure the MTRP measurement assumption, and CSI-RS resource 0 and CSI-RS resource 1 and CSI-RS resource 2 and CSI-RS resource 3 are used to measure the STRP measurement assumption, that is, the high-layer signaling indicates that CSI-RS resource 0 and CSI-RS resource 1 can be shared.

[0172] For case 1, the port indication field (also referred to as non-PMI-PortIndication) in the configuration of non-codebook-based CSI reporting includes 3 entries, and the correspondence between the entry (portIndex4) corresponding to MTRP measurement hypothesis 0 (CSI-RS resource 0 and CSI-RS resource 1) and the layer is as shown in Table 3-2:

[0174] Table 3-2

[0175] As shown in Table 3-2, the entry corresponding to MTRP measurement hypothesis 0 in the port indication field includes 4 indication values {0, 1}, {3, 2, 1}, {1, 3, 0}, {2, 3, 1, 0} arranged in a preset order, so that the terminal can obtain the association relationship between the rank value of each TRP in the MTRP measurement hypothesis 0 and the port after obtaining the 4 indication values, for example: Rank2-1-4, and the corresponding indication value is {1, 3, 0}, which indicates that the rank value of TRP 1 is 2, and the corresponding port is {3001, 3003}, and the rank value of TRP 2 is 1, and the corresponding port is {3000}.

[0214] That is, in this embodiment, the measurement resources are all configured as 4-port resources.

[0215] This embodiment includes the following cases:
