[0021] I. INTRODUCTION

[0022] As shown in Figure 1 Channel State Information (CSI) reporting can be one CSI report including one set of CSI (single-CSI), one CSI report including multiple sets of CSI (multi-CSI), and multiple CSI reports (multi-reporting) where each CSI report includes one set of CSI. Different types of CSI reporting occupy different number of CSI processing units (CPUs). CSI can be processed based on priority. In some embodiments, priority is related to occupied CPUs. This patent document proposes methods to determine occupied CPUs and priority. This patent document further proposes methods to process CSI.

[0023] Large bandwidth multi-antenna devices are employed in 5G communication systems. Large number of spatial elements result in high power consumption.

[0024] To reduce power consumption of gNB, one potential method is to reduce the number of antennas or antenna ports. If the number of antennas is changed, the channel will be changed. To assist gNB to get the channel state of different number of antennas, multiple Channel State Information (CSI) with different antenna patterns are needed. Multiple CSI with different antenna patterns can be obtained through a specific CSI reporting configuration type.

[0025] To calculate CSI, one or more CSI processing units (CPUs) are needed. The number of CPUs that will be occupied by this specific CSI reporting configuration type and how to allocate CPUs need to be investigated.

[0026] In this patent document, a method to allocate CPUs is provided.

[0027] Channel State Information (CSI) measurement: A user equipment (UE) shall perform measurements based on CSI reference signals (CSI-RS) and can report corresponding reports to a gNB.

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

[0029] The number of ports of a CSI-RS is configured through nrofPorts in CSI-ResourceMapping. A CSI-ResourceMapping is associated with a NZP-CSI-RS-Resource. A NZP-CSI-RS-Resource is associated with a NZP-CSI-RS-ResourceSet. A NZP-CSI-RS-ResourceSet is associated with a CSI-ResourceConfig; a CSI-ResourceConfig is associated with a CSI-ReportConfig; nrofPorts can be one of: pl, p2, p4, p8, pl2, pl6, p24, p32.

[0030] A UE indicates the number of parallel CSI computations supported within a component carrier with the parameter simultaneousCSI-ReportsPerCC CPU , and the number of parallel CSI computations across all component carriers with the parameter simultaneousCSI-ReportsAllCC. If a UE supports N CPU parallel CSI computations, it is said to have N CPU CSI processing units (CPUs) for processing CSI reports. If, in a given OFDM symbol, there are L CPUs occupied for the computation of CSI reports, the UE has N CPU -L CPUs that are not occupied. If N CSI reports are in a given OFDM symbol, the UE has 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 so, the UE does not need to update its functionality.

[0031] The lowest priority NM requests for CSI reporting, where 0≤M≤N are those that satisfy... The maximum value.

[0032] 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.

[0033] 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.

[0034] The first CSI report configuration includes at least one of the following:

[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 CSI report that includes a set of CSIs.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] A CSI report configuration is associated with a CSI-RS resource. The UE reports multiple CSI reports according to some or all ports associated with the CSI-RS resource.

[0041] A CSI report configuration is associated with a CSI-RS resource and multiple PUCCH resource parameter sets. The UE reports multiple CSI reports according to different PUCCH resource parameter sets. In other words, the UE reports multiple CSI reports in different CSI reporting processes.

[0042] Multiple CSI report configurations are associated with one CSI-RS resource. The UE reports multiple CSI reports according to some or all ports associated with the CSI-RS resource.

[0043] 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 some ports of the CSI-RS resource. In some embodiments, the CSI-related quantities in the CSI report associated with some 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.

[0044] For example, the CSI report associated with all ports of the CSI-RS resource includes at least one of a CSI-RS resource indicator (CRI), a rank indicator (RI), a precoding matric indicator (PMI), a channel quality indicator (CQI). The CSI report associated with some ports of the CSI-RS resource includes the RI.

[0045] In some embodiments, the RI, CQI, or PMI reported in the CSI report associated with some ports of the CSI-RS resource is a differential value based on the corresponding RI, CQI, or PMI value reported in the CSI report associated with all ports of the CSI-RS resource.

[0046] In some embodiments, the multiple CSI report configurations include a reference CSI report configuration and a reference CSI report configuration.

[0047] A CSI report configuration is associated with a CSI-RS resource and multiple PUCCH resource parameter sets. The UE reports multiple CSI reports according to different PUCCH resource parameter sets. In other words, the UE reports multiple CSI reports in different CSI reporting processes.

[0048] The PUCCH resource parameter set includes at least one of the following: a periodicity and an offset of a report configuration for periodic / semi-persistent CSI reporting, a PUCCH resource list of a report configuration for CSI reported on PUCCH, a report slot offset list of a report configuration for CSI reported on PUSCH, or a reportConfigType.

[0049] In some embodiments, the CSI-RS resource is at least one of the following: a resource (e.g., configured by NZP-CSI-RS-Resource), a ResourceMapping, a resource set (e.g., configured by NZP-CSI-RS-ResourceSet), a resource setting (e.g., configured by CSI-ResourceConfig).

[0050] The antenna pattern includes at least one of the following: a number of ports, a port index indication, a group indication, a power offset, an index (e.g., resource ID, resource set ID, resource setting ID), a transmission configuration indicator (TCI), code division multiplexing (CDM), a resource mapping, a CDM group index, a frequency domain resource, a time domain resource. Different antenna patterns means that at least one of the multiple antenna patterns is different.

[0051] The power offset corresponds to powerControlOffset or powerControlOffsetSS. The number of ports refers to the number of CSI-RS ports.

[0052] powerControlOffset: which refers to the ratio of the assumed PDSCH (Physical Downlink Shared Channel) energy per resource element (EPRE) to non-zero power (NZP) CSI-RS EPRE when the UE derives CSI feedback. The value range of powerControlOffset is [-8, 15] dB, with a step size of 1 dB.

[0053] powerControlOffsetSS: which refers to the ratio of the assumed NZP CSI-RS EPRE to SS / PBCH (synchronization signal / physical broadcast channel) block EPRE.

[0054] In some embodiments, the CSI report configuration corresponds to a CSI-ReportConfig configured by RRC signaling.

[0055] A set of CSI can include at least one of the following: CRI (CSI-RS Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), LI (Layer Indicator), CQI (Channel Quality Indicator). In some embodiments, each set of CSI is derived based on one antenna pattern, or a subset of ports of a CSI-RS resource, or all ports of a CSI-RS resource.

[0056] In some embodiments, processing the one or more CSI reports according to the predefined rule comprises determining a priority of each CSI report.

[0057] determining a priority of each CSI report.

[0058] In some embodiments, the CSI report is associated with a priority value Pri iCSI (y, k, c, s) = 2 · N cells · M s · y + N cells · M s · k + M s · c + s, where

[0059] y = 0 for aperiodic CSI reports to be carried on a physical uplink shared channel (PUSCH); y = 1 for semi-persistent CSI reports to be carried on a PUSCH; y = 2 for semi-persistent CSI reports to be carried on a physical uplink control channel (PUCCH); y = 3 for periodic CSI reports to be carried on a PUCCH;

[0060] k = 0 for CSI reports carrying L1-RSRP (reference signal received power) or L1-SINR (Signal to Interference plus Noise Ratio); k = 1 for CSI reports not carrying L1-RSRP or L1-SINR;

[0061] c is a serving cell index, and N cellsfor the value of the higher layer parameter maxNrofServingCells (maximum number of serving cells);

[0062] s is a reportConfigID (report configuration ID), M s for the value of the higher layer parameter maxNrofCSI-ReportConfigurations (maximum number of CSI report configurations).

[0063] A first CSI report is said to have a higher priority than a second CSI report if the associated value for the first report is lower than the associated value for the second report.

[0064] In some embodiments, the priority of a CSI report is determined based on a Pri value. The Pri value is determined according to at least one of the following: a time domain behavior type (y) of the report configuration, a type of CSI-related quantity to be reported (k), a serving cell index (c), a value of the higher layer parameter maxNrofServingCells (Ncells), a reportConfigID (s), a value of the higher layer parameter maxNrofCSI-ReportConfigurations (Ms), a CSI report type indicator (r), a multi-CSI indication (m), a number indication of CSI reports (n), a multi-reporting indication, a number of PUCCH resource parameter sets, or a scaling factor (f).

[0065] In some embodiments, the Pri value is determined according to y, k, c, Ncells, s, and Ms. The Pri value of a CSI report is determined according to at least one of the following:

[0066] Pri iCSI (y, k, c, s) = 2 · N cells · M s · y + N cells · M s · k + M s · c + s

[0067] In some embodiments, different types of CSI reports correspond to different values of k. For example, for a reference CSI report, k = 1 or k = 2. For a multi-CSI report, a multi-reporting, or a benchmark CSI report, k = 0 or k = 1.

[0068] For example, for a CSI report, a multi-CSI report, a multi-reporting, or a benchmark CSI report that carries L1-RSRP (reference signal received power) or L1-SINR (signal to interference plus noise ratio), k = 0; and for other CSI reports, k = 1.

[0069] In some embodiments, the Pri value is determined according to y, k, c, Ncells, s, and Ms. The Pri value of the CSI report is determined according to at least one of the following:

[0070] Pri iCSI (y, k, c, s) = 2 · N cells · M s · y + N cells · M s · k + M s · c + s

[0071] In some embodiments, different types of CSI reports correspond to different y values. For example, for a semi-persistent CSI report, a multi-CSI report, a multi-reporting, or a reference CSI report to be carried on a physical uplink shared channel (PUSCH), y = 1. For example, for a reference CSI report, y = 2, y = 3, or y = 4. For a multi-CSI report, a multi-reporting, or a reference CSI report, y = 0, y = 1, or y = 2.

[0072] For example, for an aperiodic CSI report, a CSI report carrying L1-SINR (signal to interference plus noise ratio), a multi-CSI report, a multi-reporting, or a reference CSI report to be carried on a physical uplink shared channel (PUSCH), y = 0; for a semi-persistent CSI report or a reference CSI report to be carried on a PUSCH, y = 1; for a semi-persistent CSI report to be carried on a physical uplink control channel (PUCCH), y = 2; for a periodic CSI report to be carried on a PUCCH, y = 3.

[0073] In some embodiments, a CSI report configuration configures multiple CSI reports. The multiple CSI reports include a reference CSI report and a reference CSI report.

[0074] The CSI report type indicator is a value regarding whether the CSI report is a third CSI report or a 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. 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.

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

[0076] In some embodiments, the fourth CSI report means that the CSI (e.g., at least one of RI, CQI or PMI) reported in the fourth CSI report is a differential value based on the CSI (e.g., at least one of RI, CQI or PMI) reported in the third CSI report. In some embodiments, the third CSI report corresponds to the reference CSI report.

[0077] In some embodiments, the reference CSI report and the reference CSI report are configured in one CSI reporting configuration. In some embodiments, the reference CSI report and the reference CSI report are configured in different CSI reporting configurations.

[0078] In some embodiments, whether a CSI report is the fourth report is configured by higher layer signaling.

[0079] II. Example 1

[0080] The Pri value is determined according to: y, k, c, Ncells, s, Ms, r. The Pri value of a CSI report is determined according to at least one of the following:

[0081] Pri(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

[0082] In some embodiments, the values of r, r1, r2, r3, r4 and r5 are non-negative. In some embodiments, r1, r2, r3, r4 can be present or absent. The value of at least one of r1, r2, r3, r4 can be 1, can be the same as r or the same as a scaling factor (f). r5 can be present or absent. The value of r5 can be 0 or can be the same as r. r is a CSI report type indicator.

[0083] For example, the Pri value of a CSI report is determined according to at least one of the following:

[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) = r • (2 • N cells • M s • y + N cells • M s • k + M s • c + s),

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

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

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

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

[0093] Pri(y, k, c, s, r) = 2 · N cells • M s • y + N cells • M s • k + M s • c + s + r

[0094] The multi-CSI indication is a value regarding whether the CSI report is configured as a multi-CSI report. For example, if the CSI report is configured as a multi-CSI report, the multi-CSI indication is 0. Otherwise, the multi-CSI indication is 1. For another example, if the CSI report is configured as a multi-CSI report, the multi-CSI indication is 1. Otherwise, the multi-CSI indication is 0.

[0095] In some embodiments, the multi-CSI report configuration means that the UE reports multiple sets of CSI in one CSI report.

[0096] In some embodiments, the multi-CSI report configuration means that the UE can report one or more sets of CSI in one CSI report.

[0097] In some embodiments, whether the CSI report is configured as a multi-CSI report is determined according to a higher layer signaling. In other words, the higher layer signaling indicates whether the CSI report is configured as a multi-CSI report. In some embodiments, the higher layer signaling is configured in CSI-ReportConfig.

[0098] III. Example 2

[0099] The Pri value is determined according to y, k, c, Ncells, s, Ms, and m. The Pri value of the CSI report is determined according to at least one of the following:

[0100] 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

[0101] In some embodiments, the values of m, m1, m2, m3, m4, and m5 are non-negative. In some embodiments, m1, m2, m3, m4 can be present or absent. The values of m1, m2, m3, m4 can be 1, can be the same as m, or can be the same as a scaling factor (f). m5 can be present or absent. The value of m5 can be 0, or the same as m. The scaling factor can be 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 indication.

[0102] For example, the Pri value of a CSI report is determined according to at least one of the following:

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

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

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

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

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

[0112] Pri(y, k, c, s, m) = 2 · N cells • M s • y + N cells • M s • k + M s • c + s + m

[0113] In some embodiments, the number of CSI groups indication is a value regarding whether multiple groups of CSI are reported in one report according to the CSI report. For example, if multiple groups of CSI are reported in one report, the number of CSI groups indication is 0. Otherwise, the number of CSI groups indication is 1. For another example, if multiple groups of CSI are reported in one report, the number of CSI groups indication is 1. Otherwise, the number of CSI groups indication is 0.

[0114] IV. Example 3

[0115] The Pri value is determined according to: y, k, c, Ncells, s, Ms, n. The Pri value of the CSI report is determined according to at least one of the following:

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

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

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

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

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

[0125] Pri(y, k, c, s, n) = 2 · N cells • M s • y + N cells • M s • k + M s • c + s + n

[0126] In some embodiments, n has a value of non-negative. In some embodiments, the number-of-CSI-groups indication is a value regarding the number of CSI groups reported in one report according to the CSI report. For example, the number-of-CSI-groups indication is the same as the number of CSI groups reported in one report. For another example, the number-of-CSI-groups indication is equal to the number of CSI groups reported in one report minus 1. For yet another example, the number-of-CSI-groups indication is equal to the number of antenna patterns configured or selected for the CSI report configuration.

[0127] The number of CSI groups reported in one report is configured by RRC signaling, indicated by downlink control information (DCI), indicated by a media access control (MAC) control element (CE), or derived according to the number of antenna patterns configured or selected for the CSI report configuration.

[0128] V. Example 4

[0129] The Pri value is determined according to y, k, c, Ncells, s, Ms, and n. The Pri value of the CSI report is determined according to at least one of the following:

[0130] 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

[0131] In some embodiments, the values of n, n1, n2, n3, n4, and n5 are non-negative. In some embodiments, n1, n2, n3, n4 can or can not be present. The values of n1, n2, n3, n4 can be 1, or the same as n, or the same as the scaling factor (f); n5 can or can not be present. The value of n5 can be 0, or the same as n. The scaling factor can be 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 the number of CSI groups.

[0132] For example:

[0133] Pri(y, k, c, s, n) = n · (2 · N cells · M s · y + N cells · M s · k) + M s · c + s,

[0134] Pri(y, k, c, s, n) = n · (2 · N cells · M s · y + N cells · M s · k + M s · c) + s,

[0135] Pri(y, k, c, s, n) = n · (2 · N cells · M s · y + N cells · M s · k + M s · c + s),

[0150]

[0151] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+function[s / n],

[0152] Pri(y,k,c,s,n)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+n, or

[0153] Pri(y,k,c,s,n)=function[2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+sn]

[0154] In some embodiments, function[X] means preserving the original value or rounding the original value up or down.

[0155] In some embodiments, if X is greater than or equal to 0, function[X] means to retain the original value; if X is less than 0, the value is set to 0.

[0157] 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:

[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,

[0168] 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.

[0169] VII. Example 6

[0170] The Pri value is determined based on the following: y, k, c, Ncells, s, Ms, and p. The Pri value of a CSI report configured in a CSI report configuration is determined based on at least one of the following:

[0171] Pri(y,k,c,s,p)=p1·2·N cells ·M s ·y+p2·Ncells ·M s ·k+p3·M s ·c+p4·s+p5

[0172] 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.

[0173] For example:

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

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

[0183] Pri(y,k,c,s,p)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s+p

[0184] 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.

[0185] VIII. Example 7

[0186] The Pri value is determined based on the following: y, k, c, N cells, 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. For another 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. For yet another 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:

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

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

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

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

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

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

[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},

[0201] 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},

[0299] 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.

[0300] O CPU =1.

[0301] O CPU =0.

[0302] O CPU =u.

[0303] O CPU = u*Ky, where Ky is the number of active CSI-RS resources used for channel measurements in this CSI report.

[0304] 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.

[0305] In some embodiments, u is a predefined value.

[0306] In some embodiments, u is a value reported by the UE (e.g., UE capability).

[0307] In some embodiments, u is a value indicated by RRC, MAC CE, or DCI.

[0308] In some embodiments, the value indicated by RRC, MAC CE, or DCI should not exceed the UE's capability.

[0309] In some embodiments, u has different values ​​for different numbers of CSI groups reported in a report.

[0310] 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 =Ky, where Ky is the number of active CSI-RS resources used for channel measurements.

[0313] O CPU =K s , where K s It is the number of CSI-RS resources in the CSI-RS resource set used for channel measurements.

[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 .

[0315] 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 =N CPU .

[0317] In some embodiments, when L=0, the CPU is occupied, and for all CSI reports configured in a CSI report configuration, O CPU =N CPU -L.

[0318] 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.

[0319] 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.

[0360] 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.

[0361] Example: such as Figure 2As 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.

[0362] 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.

[0365] 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.

[0366] The NZP CSI-RS resource is active during the period defined below.

[0371] 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.
