[0021] I.Preface

[0022] like Figure 1 As shown, a Channel State Information (CSI) report can be a single CSI report comprising a set of CSIs, a multi-CSI report comprising multiple sets of CSIs, or multiple CSI reports where each CSI report comprises a set of CSIs (multi-reporting). Different types of CSI reports occupy different numbers of CSI processing units (CPUs). CSIs can be processed based on priority. In some embodiments, priority is related to the CPU used. This patent document proposes a method for determining the CPU used and the priority. This patent document further proposes a method for processing CSIs.

[0023] 5G communication systems employ high-bandwidth, multi-antenna devices. The large number of spatial elements results in very high power consumption.

[0024] To reduce gNB power consumption, one potential approach is to reduce the number of antennas or antenna ports. If the number of antennas changes, the channel will change accordingly. To assist the gNB in ​​obtaining channel states for different numbers of antennas, multiple Channel State Information (CSI) reports with different antenna patterns are needed. Multiple CSI reports with different antenna patterns can be obtained through specific CSI report configuration types.

[0025] Calculating CSI requires one or more CSI processing units (CPUs). It is necessary to investigate the number of CPUs required for this specific CSI report configuration type and how to allocate those CPUs.

[0026] This patent document provides a method for allocating CPU resources.

[0027] Channel State Information (CSI) Measurement: User Equipment (UE) shall perform measurements based on the CSI reference signal (CSI-RS) and may report the corresponding data to the gNB.

[0028] A UE can be configured with one or more CSI reporting configurations. Each CSI reporting configuration is configured via CSI-ReportConfig signaling. CSI-ReportConfig is associated with one or more CSI-RS resource configurations via CSI-resourceConfigID. CSI-RS resource settings are configured via CSI-ResourceConfig signaling.

[0029] The number of ports for CSI-RS is configured through `nrofPorts` in CSI-ResourceMapping. CSI-ResourceMapping is associated with NZP-CSI-RS-Resource (non-zero power CSI-RS resource). NZP-CSI-RS-Resource is associated with NZP-CSI-RS-ResourceSet (non-zero power CSI-RS resource set). NZP-CSI-RS-ResourceSet is associated with CSI-ResourceConfig; CSI-ResourceConfig is associated with CSI-ReportConfig; `nrofPorts` can be one of the following: p1, p2, p4, p8, p12, p16, p24, p32.

[0030] The UE uses the parameter simultaneousCSI-ReportsPerCC (parallel CSI reports per component carrier) to indicate the number N of parallel CSI calculations supported within a component carrier. CPU The parameter `simultaneousCSI-ReportsAllCC` indicates the number of parallel CSI calculations across all component carriers. If the UE supports N... CPU If there are N parallel CSI computations, then it is said to have N CPU There are L CSI processing units (CPUs) used for processing CSI reports. If, in a given OFDM symbol, L CPUs are occupied for CSI report calculation, then the UE has N CPU -L unused CPUs. If N CSI reports are in a state with N CPU-L unoccupied CPUs begin occupying their respective CPUs on the same OFDM symbol (where each CSI report corresponds to n=0,…,N-1). If the UE does not need to update the CSI reports of the NM requests with the lowest priority, where 0 ≤ M ≤ N is a condition that satisfies the condition, then the UE does not need to update the CSI reports of the NM requests with the lowest priority. The maximum value.

[0031] In other words, if the UE needs to report N CSI reports, and the usage of N CSI reports exceeds N... CPU If this is the case, some low-priority CSI reports may not need to be calculated. Therefore, prioritization rules for different CSI report types are crucial.

[0032] In some embodiments, the predefined rule is: if N CSI reports have N CPU -L unoccupied CPUs begin occupying their respective CPUs on the same OFDM symbol (where each CSI report corresponds to n=0,…,N-1). If the UE does not need to update the CSI reports of the NM requests with the lowest priority, where 0 ≤ M ≤ N is a condition that satisfies the condition, then the UE does not need to update the CSI reports of the NM requests with the lowest priority. The maximum value. Otherwise, the UE needs to update all N CSI reports.

[0033] The first CSI report configuration includes at least one of the following:

[0034] The CSI report configuration is associated with a CSI-RS resource. The UE uses some or all of the ports associated with the CSI-RS resource to perform CSI report calculations and reports a CSI report that includes a set of CSIs.

[0035] The CSI report configuration is associated with a CSI-RS resource. The UE uses some or all of the ports associated with the CSI-RS resource to perform CSI report calculations and reports a single CSI report that includes multiple sets of CSIs.

[0036] The CSI report configuration is associated with a CSI-RS resource configured with multiple antenna patterns. The UE reports a CSI report based on one antenna pattern from the multiple antenna images.

[0037] The CSI report configuration is associated with a CSI-RS resource configured with multiple antenna patterns. The UE reports a single CSI report containing multiple sets of CSIs based on multiple antenna patterns.

[0038] The CSI report configuration is associated with a CSI-RS resource configured with multiple antenna patterns. The UE reports multiple CSI reports based on the multiple antenna patterns.

[0039] CSI reporting configuration is associated with CSI-RS resources. The UE reports multiple CSI reports based on some or all of the ports associated with that CSI-RS resource.

[0040] CSI report configuration is associated with CSI-RS resources and multiple PUCCH resource parameter sets. The UE reports multiple CSI reports based on different PUCCH resource parameter sets. In other words, the UE reports multiple CSI reports during different CSI reporting processes.

[0041] Multiple CSI report configurations are associated with a CSI-RS resource, and the UE reports multiple CSI reports based on some or all of the ports associated with the CSI-RS resource.

[0042] In some embodiments, the CSI-related quantities in the CSI report associated with all ports of the CSI-RS resource are different from the CSI-related quantities in the CSI report associated with a subset of ports of the CSI-RS resource. In some embodiments, the CSI-related quantities in the CSI report associated with a subset of ports of the CSI-RS resource are a subset of the CSI-related quantities in the CSI report associated with all ports of the CSI-RS resource.

[0043] For example, a CSI report associated with all ports of a CSI-RS resource includes at least one of the following: CSI-RS resource indicator (CRI), rank indicator (RI), precoding matrix indicator (PMI), and channel quality indicator (CQI). A CSI report associated with only some ports of a CSI-RS resource includes the RI.

[0044] In some embodiments, the RI, CQI, or PMI reported in a CSI report associated with a portion of a CSI-RS resource is a difference between the corresponding RI, CQI, or PMI values ​​reported in a CSI report associated with all ports of the CSI-RS resource.

[0045] In some embodiments, the multiple CSI report configurations include a baseline CSI report configuration and a reference CSI report configuration.

[0046] CSI report configuration is associated with CSI-RS resources and multiple PUCCH resource parameter sets. The UE reports multiple CSI reports based on different PUCCH resource parameter sets. In other words, the UE reports multiple CSI reports during different CSI reporting processes.

[0047] The PUCCH resource parameter set includes at least one of the following: the period and offset of the report configuration for periodic / semi-persistent CSI reports, the PUCCH resource list for the CSI report configuration reported on the PUCCH, the report slot offset list for the CSI report configuration reported on the PUSCH, or reportConfigType (report configuration type).

[0048] In some embodiments, a CSI-RS resource is at least one of the following: a resource (e.g., configured via NZP-CSI-RS-Resource), a resource mapping, a resource set (e.g., configured via NZP-CSI-RS-ResourceSet), or a resource setting (e.g., configured via CSI-ResourceConfig).

[0049] Antenna patterns include at least one of the following: number of ports, port index indication, group indication, power offset, index (e.g., resource ID, resource set ID, resource setting ID), transmission configuration indicator (TCI), code division multiplexing (CDM), resource mapping, CDM group index, frequency domain resources, and time domain resources. Different antenna patterns mean that at least one of multiple antenna patterns is different.

[0050] Power offset corresponds to powerControlOffset or powerControlOffsetSS (synchronization signal power control offset). The number of ports refers to the number of CSI-RS ports.

[0051] powerControlOffset: This refers to the ratio of the energy per resource element (EPRE) of the PDSCH (Physical Downlink Shared Channel) to the non-zero power (NZP) CSI-RS EPRE assumed when the UE derives CSI feedback. The value range of powerControlOffset is [-8, 15] dB, with a step size of 1 dB.

[0052] powerControlOffsetSS: This refers to the ratio of the assumed NZP CSI-RS EPRE to the SS / PBCH (synchronization signal / physical broadcast channel) block EPRE.

[0053] In some embodiments, the CSI report configuration corresponds to the CSI-ReportConfig configured by RRC signaling.

[0054] A set of CSIs may include at least one of the following: CRI (CSI-RS Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), LI (Layer Indicator), and CQI (Channel Quality Indicator). In some embodiments, each set of CSIs is obtained based on an antenna pattern, a portion of the ports of a CSI-RS resource, or all the ports of a CSI-RS resource.

[0055] In some embodiments, processing one or more CSI reports according to predefined rules includes determining the priority of each CSI report.

[0056] Determine the priority of each CSI report.

[0057] In some embodiments, CSI reports are associated with priority values. iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s • c+s are related, where

[0058] For non-periodic CSI reports to be carried on the physical uplink shared channel (PUSCH), y = 0; for semi-persistent CSI reports to be carried on the PUSCH, y = 1; for semi-persistent CSI reports to be carried on the physical uplink control channel (PUCCH), y = 2; for periodic CSI reports to be carried on the PUCCH, y = 3.

[0059] For CSI reports that include L1-RSRP (reference signal received power) or L1-SINR (Signal to Interference plus Noise Ratio), k = 0; for CSI reports that do not include L1-RSRP or L1-SINR, k = 1.

[0060] c is the serving cell index, and N cellsThis is the value of the higher-level parameter maxNrofServingCells (maximum number of serving cells);

[0061] s stands for reportConfigID (report configuration ID), M s This is the value of the high-level parameter maxNrofCSI-ReportConfigurations (maximum number of CSI report configurations).

[0062] If the correlation value for the first report is lower than that for the second report, then the first CSI report is said to have a higher priority than the second CSI report.

[0063] In some embodiments, the priority of CSI reports is determined based on a Pri value. The Pri value is determined according to at least one of the following: the time-domain behavior type of the report configuration (y), the CSI-related report volume type (k), the serving cell index (c), the value of the higher-layer parameter maxNrofServingCells (Ncells), reportConfigID(s), the value of the higher-layer parameter maxNrofCSI-ReportConfigurations (Ms), the CSI report type indicator (r), the multi-CSI indicator (m), the number of CSI groups indicator (n), the multi-reporting indicator, the number of PUCCH resource parameter sets, or the scaling factor (f).

[0064] In some embodiments, the Pri value is determined based on the following: y, k, c, Ncells, s, and Ms. The Pri value reported by CSI is determined based on the following:

[0065] Pri iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s

[0066] In some embodiments, different types of CSI reports correspond to different k values. For example, for a reference CSI report, k = 1 or k = 2. For multi-CSI reports, multi-reporting, or benchmark CSI reports, k = 0 or k = 1.

[0067] For example, for CSI reports, multi-CSI reports, multi-reporting, or baseline CSI reports carrying L1-RSRP (Reference Received Power) or L1-SINR (Signal-to-Interference-plus-Noise Ratio), k = 0; while for other CSI reports, k = 1.

[0068] In some embodiments, the Pri value is determined based on the following: y, k, c, Ncells, s, and Ms. The Pri value reported by CSI is determined based on the following:

[0069] Pri iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s

[0070] In some embodiments, different types of CSI reports correspond to different y values. For example, for semi-persistent CSI reports, multi-CSI reports, multi-reporting, or baseline CSI reports to be carried on a PUSCH, y = 1. For reference CSI reports, y = 2, y = 3, or y = 4. For multi-CSI reports, multi-reporting, or baseline CSI reports, y = 0, y = 1, or y = 2.

[0071] For example, for non-periodic CSI reports, CSI reports carrying L1-SINR (signal-to-interference-plus-noise ratio), multi-CSI reports, multi-reporting, or reference CSI reports to be carried on the Physical Uplink Shared Channel (PUSCH), y = 0; for semi-persistent CSI reports or reference CSI reports to be carried on the PUSCH, y = 1; for semi-persistent CSI reports to be carried on the Physical Uplink Control Channel (PUCCH), y = 2; and for periodic CSI reports to be carried on the PUCCH, y = 3.

[0072] In some embodiments, the CSI report configuration configures multiple CSI reports. These multiple CSI reports include a baseline CSI report and a reference CSI report.

[0073] The CSI report type indicator is a value related to whether the CSI report is a third or fourth CSI report. For example, if the CSI report is a fourth CSI report, the CSI report type indicator is 1. Otherwise, the CSI report type indicator is 0. Again, for example, if the CSI report is a third CSI report, the CSI report type indicator is 0; if the CSI report is a fourth CSI report, the CSI report type indicator is 1.

[0074] In some embodiments, a fourth CSI report means that a CSI (e.g., at least one of RI, CQI, or PMI) references (or is based on) a corresponding CSI in another CSI report (e.g., a third CSI report). In some embodiments, a fourth CSI report corresponds to a referenced CSI report.

[0075] In some embodiments, a fourth CSI report means that the CSI reported in the fourth CSI report (e.g., at least one of RI, CQI, or PMI) is a difference based on the CSI reported in the third CSI report (e.g., at least one of RI, CQI, or PMI). In some embodiments, the third CSI report corresponds to a benchmark CSI report.

[0076] In some embodiments, the baseline CSI report and the reference CSI report are configured in a single CSI report configuration. In other embodiments, the baseline CSI report and the reference CSI report are configured in separate CSI report configurations.

[0077] In some embodiments, whether a CSI report is a fourth CSI report is configured by higher-level signaling.

[0078] II. Example 1

[0079] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, r. The Pri value reported by CSI is determined based on the following:

[0080] Pr i(y,k,c,s,r)=r1·2·N cells ·M s ·y+r2·N cells ·M s ·k+r3·M s ·c+r4·s+r5

[0081] In some embodiments, the values ​​of r, r1, r2, r3, r4, and r5 are non-negative. In some embodiments, r1, r2, r3, and r4 may or may not exist. The value of at least one of r1, r2, r3, and r4 may be 1, the same as r, or the same as the scaling factor (f). r5 may or may not exist. The value of r5 may be 0 or the same as r. r is a CSI report type indicator.

[0082] For example, the Pri value reported by CSI is determined based on at least one of the following:

[0083] Pri(y,k,c,s,r)=r·(2·N cells ·M s ·y+N cells ·M s ·k)+M s·c+s,

[0084] Pri(y,k,c,s,r)=r·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s,

[0085] Pri(y,k,c,s,r)=r·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s),

[0086] Pri(y,k,c,s,r)=2·N cells ·M s ·y+N cells ·M s ·k+r·(M s ·c+s),

[0087] Pri(y,k,c,s,r)=2·N cells ·M s ·y+r·(N cells ·M s ·k+M s ·c+s),

[0088] Pri(y,k,c,s,r)=2·N cells ·M s ·y·r+N cells ·M s ·k+M s ·c+s,

[0089] Pri(y,k,c,s,r)=2·N cells ·M s ·y+N cells ·M s ·k·r+M s ·c+s,

[0090] Pri(y,k,c,s,r)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c·r+s,

[0091] Pri(y,k,c,s,r)=2·N cells ·M s ·y+N cells ·Ms ·k+M s ·c+s·r, or

[0092] Pri(y,k,c,s,r)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+r

[0093] The multi-CSI indicator is a value indicating whether CSI reporting is configured for multi-CSI reporting. For example, if CSI reporting is configured for multi-CSI reporting, the multi-CSI indicator is 0. Otherwise, the multi-CSI indicator is 1. Again, for example, if CSI reporting is configured for multi-CSI reporting, the multi-CSI indicator is 1. Otherwise, the multi-CSI indicator is 0.

[0094] In some embodiments, the multi-CSI reporting configuration means that the UE reports multiple sets of CSIs in a single CSI report.

[0095] In some embodiments, the multi-CSI reporting configuration means that the UE can report one or more sets of CSIs in a single CSI report.

[0096] In some embodiments, whether a CSI report is configured as a multi-CSI report is determined based on higher-level signaling. In other words, higher-level signaling indicates whether a CSI report is configured as a multi-CSI report. In some embodiments, this higher-level signaling is configured in CSI-ReportConfig.

[0097] III. Example 2

[0098] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, and m. The Pri value reported by CSI is determined based on the following:

[0099] Pri(y,k,c,s,m)=m1·2·N cells ·M s ·y+m2·N cells ·M s ·k+m3·M s ·c+m4·s+m5

[0100] In some embodiments, the values ​​of m, m1, m2, m3, m4, and m5 are non-negative. In some embodiments, m1, m2, m3, and m4 may or may not exist. The values ​​of m1, m2, m3, and m4 may be 1, the same as m, or the same as the scaling factor (f). m5 may or may not exist. The value of m5 may be 0 or the same as m. The scaling factor may have different values ​​for different CSI reports. For example, if the CSI report is a multi-CSI report, the scaling factor is 0; if the CSI report is not a multi-CSI report, the scaling factor is 1. m is a multi-CSI indicator.

[0101] For example, the Pri value reported by CSI is determined based on at least one of the following:

[0102] Pri(y,k,c,s,m)=m·(2·N cells ·M s ·y+N cells ·M s ·k)+M s ·c+s,

[0103] Pri(y,k,c,s,m)=m(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s,

[0104] Pri(y,k,c,s,m)=m·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s),

[0105] Pri(y,k,c,s,m)=2·N cells ·M s ·y+N cells ·M s ·k+m·(M s ·c+s),

[0106] Pri(y,k,c,s,m)=2·N cells ·M s ·y+m·(N cells ·M s ·k+M s ·c+s),

[0107] Pri(y,k,c,s,m)=2·N cells ·M s ·y·m+N cells·M s ·k+M s ·c+s,

[0108] Pri(y,k,c,s,m)=2·N cells ·M s ·y+N cells ·M s ·k·m+M s ·c+s,

[0109] Pri(y,k,c,s,m)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c·m+s,

[0110] Pri(y,k,c,s,m)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s·m, or

[0111] Pri(y,k,c,s,m)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+m

[0112] In some embodiments, the number of CSI groups is a value relating to whether multiple CSI groups are reported in a single report. For example, if multiple CSI groups are reported in a single report, the number of CSI groups is 0. Otherwise, the number of CSI groups is 1. Again, for example, if multiple CSI groups are reported in a single report, the number of CSI groups is 1. Otherwise, the number of CSI groups is 0.

[0113] IV. Example 3

[0114] The Pri value is determined based on the following: y, k, c, N cells ,s,Ms,n. The Pri value reported by CSI is determined based on at least one of the following:

[0115] Pri(y,k,c,s,n)=n·(2·N cells ·M s ·y+N cells ·M s ·k)+M s ·c+s,

[0116] Pri(y,k,c,s,n)=n·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s,

[0117] Pri(y,k,c,s,n)=n·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s),

[0118] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+n·(M s ·c+s),

[0119] Pri(y,k,c,s,n)=2·N cells ·M s ·y+n·(N cells ·M s ·k+M s ·c+s),

[0120] Pri(y,k,c,s,n)=2·N cells ·M s ·y·n+N cells ·M s ·k+M s ·c+s,

[0121] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k·n+M s ·c+s,

[0122] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c·n+s,

[0123] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+M s·c+s·n, or

[0124] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+n

[0125] In some embodiments, the value of n is non-negative. In some embodiments, the number of CSI groups indicated is a value relating to the number of CSI groups reported in a report based on the CSI report. For example, the number of CSI groups indicated is the same as the number of CSI groups reported in a report. Another example is that the number of CSI groups indicated is equal to the number of CSI groups reported in a report minus 1. Yet another example is that the number of CSI groups indicated is equal to the number of antenna patterns configured or selected for the CSI report.

[0126] The number of CSI groups reported in a report is configured by RRC signaling, indicated by downlink control information (DCI), indicated by media access control (MAC) control elements (CE), or derived from the number of antenna patterns configured or selected for CSI reporting.

[0127] V. Example 4

[0128] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, and n. The Pri value reported by CSI is determined based on the following:

[0129] Pri(y,k,c,s,n)=n1·2·N cells ·M s ·y+n2·N cells ·M s ·k+n3·M s ·c+n4·s+n5

[0130] In some embodiments, the values ​​of n, n1, n2, n3, n4, and n5 are non-negative. In some embodiments, n1, n2, n3, and n4 may or may not exist. The values ​​of n1, n2, n3, and n4 may be 1, the same as n, or the same as the scaling factor (f); n5 may or may not exist. The value of n5 may be 0 or the same as n. The scaling factor may have different values ​​for different CSI reports. For example, if the CSI report is a multi-CSI report, the scaling factor is 0; if the CSI report is not a multi-CSI report, the scaling factor is 1; n is an indicator of the number of CSI groups.

[0156] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, m, n. The Pri value reported by CSI is determined based on at least one of the following:

[0157] Pri(y,k,c,s,m,n)=m·(2·N cells ·M s ·y+N cells·M s ·k)+M s ·c+s+n,

[0158] Pri(y,k,c,s,m,n)=m·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s+n,

[0159] Pri(y,k,c,s,m,n)=m·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s)+n,

[0167] The multi-reporting indicator (p) is a value relating to whether the UE reports multiple CSI reports in the first CSI report configuration. For example, if the CSI reporting configuration does not require reporting multiple CSI reports in different PUCCH resources, then p = 0; if the CSI reporting configuration requires reporting multiple CSI reports in different PUCCH resources, then p = 1. Again, for example, if the CSI reporting configuration does not require reporting multiple CSI reports in different PUCCH resources, then p = 1; if the CSI reporting configuration requires reporting multiple CSI reports in different PUCCH resources, then p = 0. The multi-reporting indicator (p) is a value relating to the number of CSI reporting procedures configured in the CSI reporting configuration. In some embodiments, the number of CSI reporting procedures configured in the CSI reporting configuration is equivalent to the number of PUCCH resource parameter sets configured in that CSI reporting configuration.

[0168] VII. Example 6

[0169] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, and p. The Pri value for a CSI report configured in a CSI report configuration is determined based on the following:

[0170] Pri(y,k,c,s,p)=p1·2·N cells ·M s ·y+p2·N cells ·M s ·k+p3·M s ·c+p4·s+p5

[0171] In some embodiments, the values ​​of p, p1, p2, p3, p4, and p5 are non-negative. In some embodiments, p1, p2, p3, and p4 may or may not exist. The values ​​of p1, p2, p3, and p4 may be 1, the same as p, or the same as the scaling factor (f); p5 may or may not exist. The value of p5 may be 0 or the same as p.

[0172] For example:

[0173] Pri(y,k,c,s,p) = p·(2·N cells ·M s ·y + N cells ·M s ·k) + M s ·c + s,

[0174] Pri(y,k,c,s,p) = p·(2·N cells ·M s ·y + N cells ·M s ·k + M s ·c) + s,

[0175] Pri(y,k,c,s,p) = p·(2·N cells ·M s ·y + N cells ·M s ·k + M s ·c + s),

[0176] Pri(y,k,c,s,p) = 2·N cells ·M s ·y + N cells ·M s ·k + p·(M s ·c + s),

[0177] Pri(y,k,c,s,p) = 2·N cells ·M s ·y + p·(N cells ·M s ·k + M s ·c + s),

[0178] Pri(y,k,c,s,p) = 2·N cells ·M s ·y·p + N cells ·M s ·k + M s ·c + s,

[0179] Pri(y,k,c,s,p) = 2·N cells ·M s ·y + N cells ·M s ·k·p + M s ·c + s,

[0180] Pri(y,k,c,s,p) = 2·N cells ·Ms ·y+N cells ·M s ·k+M s ·c·p+s,

[0181] Pri(y,k,c,s,p)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s·p,

[0182] Pri(y,k,c,s,p)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+p

[0183] In some embodiments, the Pri value is determined at least by the number of PUCCH resource parameter sets configured in the CSI report configuration. A scaling factor f is used. For example, if no multiple PUCCH resource parameter sets are configured in the CSI report configuration, then f = 1; if multiple PUCCH resource parameter sets are configured in the CSI report configuration, then f = 0. Again, for example, if no multiple PUCCH resource parameter sets are configured in the CSI report configuration, then f = 0; if multiple PUCCH resource parameter sets are configured in the CSI report configuration, then f = 1. In some embodiments, multiple CSI reports configured in a single CSI report configuration have the same priority.

[0184] VIII. Example 7

[0185] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, and Npu. Npu is a value relating to the number of PUCCH resource parameter sets configured in the CSI report configuration. Npu is a non-negative value. For example, if no multiple PUCCH resource parameter sets are configured in the CSI report configuration, then Npu = 1; if multiple PUCCH resource parameter sets are configured in the CSI report configuration, then Npu = 0. Again, for example, if no multiple PUCCH resource parameter sets are configured in the CSI report configuration, then Npu = 0; if multiple PUCCH resource parameter sets are configured in the CSI report configuration, then Npu = 1. Again, for example, Npu equals the number of PUCCH resource parameter sets configured in the CSI report configuration. The Pri value of the CSI report is determined based on at least one of the following:

[0186] Pri(y,k,c,s,Npu)=Npu·(2·N cells ·M s ·y+N cells ·Ms ·k)+M s ·c+s,

[0187] At(y,k,c,s,Npu)=Npu·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s,

[0188] At(y,k,c,s,Npu)=Npu·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s),

[0189] At(y,k,c,s,Npu)=2·N cells ·M s ·y+N cells ·M s ·k+Npu·(M s ·c+s),

[0190] At(y,k,c,s,Npu)=2·N cells ·M s ·y+Npu·(N cells ·M s ·k+M s ·c+s),

[0191] At(y,k,c,s,Npu)=2·N cells ·M s ·y·Npu+N cells ·M s ·k+M s ·c+s,

[0192] At(y,k,c,s,Npu)=2·N cells ·M s ·y+N cells ·M s ·k·Npu+M s ·c+s,

[0199] Pri(y,k,c,s,f)=f·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c)+s+choice{Npu,m,n,r},

[0200] Pri(y,k,c,s,f)=f·(2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s)+choice{Npu,m,n,r},

[0206] Pri(y,k,c,s,f)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s·f+choice{Npu,m,n,r},

[0298] O CPU =K s , where K s This refers to the number of CSI-RS resources in the CSI-RS resource set used for channel measurements in this CSI report.

[0299] O CPU =1.

[0300] O CPU =0.

[0301] O CPU =u.

[0302] O CPU = u*Ky, where Ky is the number of active CSI-RS resources used for channel measurements in this CSI report.

[0303] O CPU =u*K s , where K s This refers to the number of CSI-RS resources in the CSI-RS resource set used for channel measurements in this CSI report.

[0304] In some embodiments, u is a predefined value.

[0305] In some embodiments, u is a value reported by the UE (e.g., UE capability).

[0306] In some embodiments, u is a value indicated by RRC, MAC CE, or DCI.

[0307] In some embodiments, the value indicated by RRC, MAC CE, or DCI should not exceed the UE's capability.

[0308] In some embodiments, u has different values ​​for different numbers of CSI groups reported in a report.

[0309] In some embodiments, for a CSI reporting configuration associated with a CSI-RS resource, the UE uses different power offset values ​​associated with that CSI-RS resource to perform CSI report calculations and reports multiple CSI groups or multiple CSI reports in one report; or for a CSI reporting configuration associated with a CSI-RS resource configured with multiple power offsets, the UE reports multiple CSI reports or multiple CSI groups in one reporting process based on multiple power offsets, and the number of CPUs occupied by this CSI reporting configuration (O CPU It is at least one of the following:

[0312] O CPU =K s , where K s It is the number of CSI-RS resources in the CSI-RS resource set used for channel measurement.

[0313] In some embodiments, when L=0, the CPU is occupied, and for CSI reports that include multiple sets of CSIs, O CPU =N CPU .

[0314] In some embodiments, when L=0, the CPU is occupied, and for CSI reports that include multiple sets of CSIs, O CPU =N CPU -L.

[0316] In some embodiments, when L=0, the CPU is occupied, and for all CSI reports configured in a CSI report configuration, O CPU =NCPU -L.

[0317] In some embodiments, the number of CSI groups reported in a report can be changed. In other words, the number of CSI groups reported in a report can be changed according to the CSI reporting configuration. For example, DCI or MAC CE indicates activation of a CSI-RS resource change. The number of CSI groups reported in a report also changes accordingly. As another example, DCI or MAC CE indicates a change in the number of CSI groups reported in a report. As yet another example, DCI or MAC CE indicates a change in the port index used to process CSI reports. The number of CSI groups reported in a report also changes accordingly. In summary, DCI or MAC CE can indicate a change associated with the first CSI reporting configuration. This change may result in a change in the number of CSI groups reported in a report.

[0318] If the number of CSI groups reported in a report changes according to the CSI report configuration, then the number of CPUs occupied by that CSI report configuration (O) CPU This may also change. Therefore, the number of CPUs used by the CSI report configuration may differ at different points in time.

[0354] The first CSI report following the first signaling-triggered CSI report change occupies one or more CPUs from the first symbol after the PDCCH until the last symbol of the configured PUSCH or PUCCH carrying the report. When PDCCH reception includes two PDCCH candidates from two independent search space sets, the PDCCH candidate that ends later in time is used to determine the duration of CPU occupation.

[0355] Example: such as Figure 2 As shown, DCI changed the number of CSI groups reported in a single report within the CSI reporting configuration. The number of CPUs used by this CSI reporting configuration varies at different times.

[0356] For the last CSI report prior to DCI, this CSI report configuration occupies CPU (0) from the first symbol of the first valid or active resource in each CSI-RS / CSI-IM / SSB resource used for channel or interference measurements until the most recent CSI-RS / CSI-IM / SSB timing prior to the first signaling.

[0359] In any time slot, it is expected that the number of active CSI-RS ports or active CSI-RS resources of the UE within the active bandwidth part (BWP) will not exceed its reporting capacity. If the first signaling indicates a change in the CSI report or indicates a change in the active CSI-RS port or active CSI-RS resource of the CSI report, then the active CSI-RS port or active CSI-RS resource configured in the CSI report will be changed.

[0360] The NZP CSI-RS resource is active during the period defined below.

[0365] If a CSI-RS resource is referenced N times by one or more CSI report configurations, then the CSI-RS resources within that CSI-RS resource are counted as N times. If all or some ports in a CSI-RS resource are used for multiple CSI groups in one or more CSI reports, then the active ports have the same value as the sum of the active ports in each CSI report.
