Abstract

Some aspects of the present disclosure provide channel state information (CSI) processing criteria. A method that may be performed by a user equipment (UE) generally includes receiving, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active, determining, based on an indication of an active downlink (DL) BWP change, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report, and taking one or more actions based at least in part on the at least one occupation time.

Claims (50)

1. An apparatus for wireless communication, the apparatus comprising:

a memory storing computer executable code; and

one or more processors coupled to the memory, the processor being configured to execute the computer executable code and cause the apparatus to:

receive, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active;

receive, from the base station, additional control signaling including an indication of an active downlink (DL) BWP change indicating when the second BWP is active;

determine if a gap from a last time-domain resource of a first DL channel carrying the control signaling to a last time-domain resource of a second DL channel carrying the additional control signaling is less than or equal to a threshold;

determine, based on the gap being less than or equal to the threshold, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report; and

take one or more actions based at least in part on the at least one occupation time.

2. The apparatus of claim 1 , wherein the one or more processors are configured to cause the apparatus to determine, based on the indication of the active DL BWP change, at least one of; a first occupation time of a first number of CPUs associated with the first CSI report, or a second occupation time of a second number of CPUs associated with the second CSI report.

3. The apparatus of claim 1 , wherein the additional control signaling comprises DL control information (DCI).

4. The apparatus of claim 3 , wherein the control signaling comprises the DCI.

5. The apparatus of claim 1 , wherein the one or more processors are configured to cause the apparatus to receive the additional control signaling, from the base station, on a control resource set (CORESET) including the control signaling.

6. The apparatus of claim 1 , wherein the one or more processors are configured to cause the apparatus to report, to the base station, CSI associated with the first CSI report or the second CSI report.

7. The apparatus of claim 1 , wherein the control signaling triggers reporting the second CSI report, and wherein the at least one occupation time is associated with the second CSI report.

8. An apparatus for wireless communication, the apparatus comprising:

a memory storing computer executable code; and

one or more processors coupled to the memory, the processor being configured to execute the computer executable code and cause the apparatus to:

generate a channel state information (CSI) trigger state that triggers reporting at least one of a first CSI report associated with a first bandwidth part (BWP) that is active or a second CSI report associated with a second BWP that is non-active;

transmit, to a user equipment (UE), additional control signaling including an indication of an active downlink (DL) BWP change indicating when the second BWP is active;

determine if a gap from a last time-domain resource of a first DL channel carrying the control signaling to a last time-domain resource of a second DL channel carrying the additional control signaling is less than or equal to a threshold;

determine, based on the gap being less than or equal to the threshold, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report; and

transmit, to the UE, control signaling indicating the CSI trigger state based on the determination.

9. The apparatus of claim 8 , wherein the one or more processors are configured to cause the apparatus to determine, based on the active DL BWP change, at least one of: a first occupation time of a first number of CPUs associated with the first CSI report, or a second occupation time of a second number of CPUs associated with the second CSI report.

10. The apparatus of claim 8 , wherein the additional control signaling comprises DL control information (DCI).

11. The apparatus of claim 8 , wherein the one or more processors are configured to cause the apparatus to transmit the additional control signaling, to the UE, on a control resource set (CORESET) including the control signaling.

12. The apparatus of claim 8 , wherein the one or more processors are configured to cause the apparatus to transmit, to the UE, the control signaling based on whether a number of occupied CPUs is less than or equal to a threshold during the at least one occupation time.

13. The apparatus of claim 8 , wherein the control signaling triggers reporting the second CSI report, and wherein the at least one occupation time is associated with the second CSI report.

14. A method of wireless communication by a user equipment, the method comprising:

receiving, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active;

receiving, from the base station, additional control signaling including an indication of an active downlink (DL) BWP change indicating when the second BWP is active;

determining if a gap from a last time-domain resource of a first DL channel carrying the control signaling to a last time-domain resource of a second DL channel carrying the additional control signaling is less than or equal to a threshold;

determining, based on the gap being less than or equal to the threshold, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report; and

taking one or more actions based at least in part on the at least one occupation time.

15. The method of claim 14 , wherein determining the at least one occupation time comprises determining, based on the indication of the active DL BWP change, at least one of: a first occupation time of a first number of CPUs associated with the first CSI report, or a second occupation time of a second number of CPUs associated with the second CSI report.
