Abstract

A method and a device for determining a priority level of a channel state information (CSI) report are provided. The method includes following operations. The UE determines priority levels of at least two CSI reports, the at least two CSI reports include a first CSI report, and the first CSI report carries Layer 1 Signal to Interference Noise Ratio (L1-SINR). The priority levels of the at least two CSI reports are used to multiplex the at least two CSI reports or drop at least a part of the at least two CSI reports in response to that there is an overlapping part in time domain resources of the at least two CSI reports.

First claim

1 . A method for determining a priority level of a channel state information (CSI) report, comprising:
determining, by a user equipment (UE), priority levels of at least two CSI reports, wherein the at least two CSI reports comprise a first CSI report, and the first CSI report carries Layer 1 Signal to Interference Noise Ratio (L1-SINR); wherein the priority levels of the at least two CSI reports are used to multiplex the at least two CSI reports or drop at least a part of the at least two CSI reports in response to that there is an overlapping part in time domain resources of the at least two CSI reports.

2 . The method of claim 1 , wherein the determining by the UE priority levels of at least two CSI reports comprises:
determining, by the UE, that the priority level of the first CSI report is lower than the priority level of a second CSI report and the priority level of the first CSI report is higher than the priority level of a third CSI report, wherein the second CSI report carries an L1-SINR, and the third CSI report carries CSI reporting quantities other than the L1-SINR and a layer-1 reference signal received power (L1-RSRP).

3 . The method of claim 2 , wherein the determining by the UE that the priority level of the first CSI report is lower than the priority level of a second CSI report and the priority level of the first CSI report is higher than the priority level of a third CSI report comprises:
determining, by the UE, that a priority value of the first CSI report is higher than a priority value of the second CSI report and the priority value of the first CSI report is lower than a priority value of the third CSI report.

4 . The method of claim 3 , wherein the CSI report is associated with a priority value Pri iCSI (y, k, c, s), and the priority value Pri iCSI (y, k, c, s) is determined according to an equation:
Pri iCSI ( y,k,c,s )=2· N cells ·M s ·y+N cells ·M s ·k+M s ·c+s
wherein y=0 for an aperiodic CSI report to be carried on a physical uplink shared channel (PUSCH), y=1 for a semi-persistent CSI report to be carried on the PUSCH, y=2 for a semi-persistent CSI report to be carried on a physical uplink control channel (PUCCH), and y=3 for a periodic CSI report to be carried on the PUCCH; k=0 for a CSI report which carries the L1-RSRP or the L1-SINR, and k=1 for a CSI report which does not carry the L1-SINR and L1-SINR; c denotes a serving cell index, and N cells denotes a value of a higher layer parameter maxNrofServingCells, s denotes a report configuration ID reportConfigID, and M s denotes a value of the higher layer parameter maxNrofCSI-ReportConfigurations.

5 . The method of claim 1 , wherein the determining by the UE priority levels of at least two CSI reports comprises:
determining, by the UE, that the priority level of the first CSI report is higher than the priority level of a second CSI report, and the priority level of the first CSI report is higher than the priority level of a third CSI report, and wherein the second CSI report carries a layer-1 reference signal received power (L1-RSRP), and the third CSI report carries CSI reporting quantities other than the L1-SINR and the L1-RSRP.

6 . The method of claim 1 , wherein the determining by the UE priority levels of at least two CSI reports comprises:
determining, by the UE, that the priority level of the first CSI report is equal to the priority level of a second CSI report, and the priority level of the first CSI report is lower than the priority level of a third CSI report, and wherein the second CSI report carries a layer-1 reference signal received power (L1-RSRP), and the third CSI report carries CSI reporting quantities other than the L1-SINR and the L1-RSRP.

7 . The method of claim 6 , wherein the determining by the UE that the priority level of the first CSI report is equal to the priority level of a second CSI report and the priority level of the first CSI report is lower than the priority level of a third CSI report comprises:
determining, by the UE, that a priority value of the first CSI report is equal to a priority value of the second CSI report, and the priority value of the first CSI report is higher than a priority value of the third CSI report.

8 . The method of claim 7 , wherein the CSI report is associated with a priority value Pri iCSI (y, k, c, s), and the priority value Pri iCSI (y, k, c, s) is determined according to an equation:
Pri iCSI ( y,k,c,s )=2· N cells ·M s ·y+N cells ·M s ·k+M s ·c+s
wherein y=0 for an aperiodic CSI report to be carried on a physical uplink shared channel (PUSCH), y=1 for a semi-persistent CSI report to be carried on the PUSCH, y=2 for a semi-persistent CSI report to be carried on a physical uplink control channel (PUCCH), and y=3 for a periodic CSI report to be carried on the PUCCH; k=0 for a CSI report which carries the L1-RSRP or the L1-SINR, and k=1 for a CSI report which does not carry the L1-RSRP or the L1-SINR; c denotes a serving cell index, and N cells denotes a value of a higher layer parameter maxNrofServingCells, s denotes a report configuration ID reportConfigID, and M s denotes a value of the higher layer parameter maxNrofCSI-ReportConfigurations.

9 . The method of claim 1 , wherein the determining by the UE priority levels of at least two CSI reports comprises:
determining, by the UE, that the priority level of the first CSI report is higher than the priority level of a second CSI report, and the priority level of the first CSI report is equal to the priority level of a third CSI report, and wherein the second CSI report carries a layer-1 reference signal received power (L1-RSRP), and the third CSI report carries CSI reporting quantities other than the L1-SINR and the L1-RSRP.

10 . The method of claim 9 , wherein the determining by the UE that the priority level of the first CSI report is higher than the priority level of a second CSI report and the priority level of the first CSI report is equal to the priority level of a third CSI report comprises:
determining, by the UE, that a priority value of the first CSI report is lower than a priority value of the second CSI report, and the priority value of the first CSI report is equal to a priority value of the third CSI report.
