Referring to fig. 1, fig. 1 is a flow chart illustrating a method for handling CSI report collision according to an embodiment of the present application. The method for handling CSI report collision shown in fig. 1 may include the following steps S101 to S103.
S101, when a first CSI report is transmitted in a physical uplink control channel, determining that the value of a first reporting coefficient of the first CSI report is a constant less than 1, and the first CSI report is an aperiodic CSI report.
In some possible embodiments, when an aperiodic CSI report (hereinafter referred to as a first CSI report for convenience of description) is transmitted on a physical uplink control channel, a reporting coefficient of the first CSI report (hereinafter referred to as a first reporting coefficient for convenience of description) may be determined.
The first report value is a constant less than 1, such as 0.5, 0, -0.5, and-1, and may be determined according to an actual application scenario, which is not limited herein.
Wherein, the first reporting coefficient of the first CSI report is determined by the physical uplink control channel and/or the periodicity of the first CSI report.
The first reporting coefficient of the first CSI report is used for handling reporting conflicts of the first CSI report and the second CSI report when the first CSI report conflicts with another CSI report (hereinafter referred to as a second CSI report for convenience of description).
S102, when the first CSI report conflicts with the second CSI report, determining that the value of a second reporting coefficient of the second CSI report is 0,1,2 or 3.
In some possible embodiments, when the first CSI report and the second CSI report collide, the reporting coefficient of the second CSI report may be determined first.
Wherein the reporting coefficient of the second CSI report is determined by the bearer channel of the second CSI report and/or the periodicity of the second CSI report.
Specifically, when the second CSI report is an aperiodic CSI report transmitted on the physical uplink shared channel, a reporting coefficient of the second CSI report takes a value of 0.
Specifically, when the second CSI report is a semi-persistent scheduling CSI report transmitted on a physical uplink shared channel, a reporting coefficient of the second CSI report takes a value of 1.
Specifically, when the second CSI report is a semi-persistent scheduling CSI report transmitted on a physical uplink control channel, a reporting coefficient of the second CSI report takes a value of 2.
Specifically, when the second CSI report is a periodic CSI report transmitted on the physical uplink control channel, the reporting coefficient of the second CSI report takes a value of 3.
That is, in the case where the first CSI report collides with the second CSI report, the second CSI report may be any one of an aperiodic CSI report transmitted on a physical uplink shared channel, a semi-persistent scheduling CSI report transmitted on a physical uplink control channel, and a periodic CSI report transmitted on a physical uplink control channel.
And S103, multiplexing the first CSI report and the second CSI report or discarding the CSI report with lower priority in the first CSI report and the second CSI report when the first reporting coefficient is not equal to the second reporting coefficient.
In some possible embodiments, in case that the first CSI report and the second CSI report collide, and a first reporting coefficient of the first CSI report and a second reporting coefficient of the second CSI report are determined, multiplexing the first CSI report and the second CSI report may be selected when the first reporting coefficient is not equal to the second reporting coefficient.
In some possible embodiments, when the first reporting coefficient is not equal to the second reporting coefficient, the CSI report with the lower priority of the first CSI report and the second CSI report may be discarded.
The priority levels of the first CSI report and the second CSI report are determined by the priority value of the first CSI report and the priority value of the second CSI report, the priority value of the first CSI report is determined by the first reporting coefficient of the first CSI report, and the priority value of the second CSI report is determined by the second reporting coefficient of the second CSI report. The higher the priority value, the lower the priority of the corresponding CSI report, and the lower the priority value, the higher the priority of the corresponding CSI report.
Specifically, the priority values of the first CSI report and the second CSI report may be determined according to the following formula:
Pri iCSI (y，k，c，s)＝2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s；
wherein, N cells The maximum number of the service cells is represented, namely the value of a high-level parameter maxNrofServinCells; ms represents the maximum number of CSI report configurations, namely the value of a high-level parameter maxNrofCSI-report configurations; y represents a report coefficient of the CSI report, c represents an index value of the serving cell, s represents a configuration sequence number of the CSI report, that is, a value of a higher-layer parameter reportConfigID, and k represents a report coefficient of the CSI report.
And the reporting coefficient of the CSI report is determined by the measurement parameter carried by the CSI.
When CSI reports and bears the receiving Power (L1-Reference Signal Received Power, L1-RSRP) of a physical layer Reference Signal or the Signal-to-noise and interference ratio (L1-Signal-to-noise and interference ratio, L1-SINR) SINR of the physical layer, k is 0; and when the CSI report carries neither L1-RSRP nor L1-SINR, the value of k is 1.
Optionally, when the CSI report carries L1-RSRP or L1-SINR, k takes the value of k 1 (ii) a When the CSI report carries neither L1-RSRP nor L1-SINR, the value of k is k 2 ，k 1 、k 2 Are all constants greater than 0 and less than 1, and k 1 Is less than or equal to k 2 . If the measurement parameter carried by the aperiodic CSI report transmitted in the physical uplink control channel is L1-RSRP, the k value when the priority value of the aperiodic CSI transmitted in the physical uplink control channel is determined is 0.4; when the first CSI report carries neither L1-RSRP nor L1-SINR, determining that the first CSI report carries the L1-RSRPK for the reported priority value may be 0.6.
Optionally, when the CSI report carries L1-RSRP or L1-SINR, k takes the value of k 1 (ii) a When the CSI report carries neither L1-RSRP nor L1-SINR, the value of k is k 2 ，k 1 Is a constant greater than 0 and less than 1, and k 2 Is a constant greater than 1. If the measurement parameter carried by the aperiodic CSI report transmitted in the physical uplink control channel is L1-RSRP, the k value when the priority value of the aperiodic CSI transmitted in the physical uplink control channel is determined is 0.4; when the first CSI report carries neither L1-RSRP nor L1-SINR, k in determining the priority value of the first CSI report may take a value of 1.2.
Referring to fig. 2, fig. 2 is another schematic flowchart of a method for handling CSI report collision according to an embodiment of the present application. The CSI report collision processing method shown in fig. 2 may include the following steps S201 to S203.
S201, when the first CSI report is transmitted in the physical uplink control channel, determining that the value of a first reporting coefficient of the first CSI report is a constant less than 1, and the first CSI report is an aperiodic CSI report.
S202, when the first CSI report conflicts with the second CSI report, determining that the value of a second reporting coefficient of the second CSI report is 0,1,2 or 3.
In some possible embodiments, the specific implementation of the steps S201 to S202 can refer to the implementation shown in steps S101 to S102 in fig. 1, and will not be described herein again.
And S203, when the first reporting coefficient is equal to the second reporting coefficient, sending any one of the first CSI report and the second CSI report, or multiplexing the first CSI report and the second CSI report, or discarding the CSI report with lower priority in the first CSI report and the second CSI report.
In some possible embodiments, when the first CSI report and the second CSI report collide and a first reporting coefficient of the first CSI report and a second reporting coefficient of the second CSI report are determined, and the first reporting coefficient is equal to the second reporting coefficient, it is stated that the first reporting coefficient takes a value of 0 and the second reporting coefficient takes a value of 0 at this time. The second CSI report is an aperiodic CSI report transmitted on the physical uplink shared channel. In the above case, either one of the first CSI report and the second CSI report may be selected to be transmitted, that is, the first CSI report or the second CSI report may be selected not to be transmitted to solve the problem of collision between the first CSI report and the second CSI report.
In some possible embodiments, when the first reporting coefficient is equal to the second reporting coefficient, the CSI report with the lower priority of the first CSI report and the second CSI report may be further selected to be discarded, so as to solve the problem of collision between the first CSI report and the second CSI report. The method for determining the priority of the first CSI report and the priority of the second CSI report may specifically refer to the implementation manner shown in step S103 in fig. 1, and is not described herein again.
In some possible embodiments, when the first reporting coefficient is equal to the second reporting coefficient, the first CSI report and the second CSI report may also be multiplexed to solve a collision problem of the first CSI report and the second CSI report.
