Techniques for uplink cancellation indication signaling

1. One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a user equipment (UE) to:

receive a radio resource control (RRC) message that includes time-frequency resource set (TFRS) configuration information to be used for cancellation indication signaling to cancel transmission of a physical uplink shared channel (PUSCH);

receive a cancellation indication to indicate, based on the TFRS configuration information, one or more time-frequency resources that are preempted; and

cancel transmission of the PUSCH on the indicated one or more time-frequency resources.

2. The one or more NTCRM of claim 1 , wherein the TFRS configuration information includes:

time-frequency information to define a time-frequency region for the cancellation indication signaling;

serving cell information to indicate one or more parameters for cancellation indication in a serving cell; and

message information to indicate one or more parameters for a downlink control information (DCI) message that includes the cancellation indication.

3. The one or more NTCRM of claim 2 , wherein the time-frequency information includes one or more of:

a starting symbol for the time-frequency region;

a time duration of the time-frequency region;

a time granularity of the time-frequency region;

a frequency range of the time-frequency region; or

a number of frequency partitions in the time-frequency region.

4. The one or more NTCRM of claim 2 , wherein the serving cell information includes one or more of:

a serving cell ID of the serving cell;

a supplementary uplink (SUL) indicator to indicate whether the TFRS configuration information is for an SUL or a normal uplink carrier of the serving cell; or

a position indicator to indicate a location of a payload of the cancellation indication in an associated DCI.

5. The one or more NTCRM of claim 2 , wherein the message information includes: a radio network temporary identifier (RNTI) to be used for the DCI; and a payload size of the DCI.

6. The one or more NTCRM of claim 1 , wherein the instructions, when executed, further cause the UE to receive a method indicator to indicate whether a cancellation indication method to be used is a dynamic method or a semi-static method.

7. The one or more NTCRM of claim 1 , wherein the TFRS configuration information includes configuration information for a plurality of time-frequency region (TFR) configurations, and wherein the instructions, when executed, further cause the UE to receive a TFR indicator to indicate one of the TFR configurations that is to be used.

8. The one or more NTCRM of claim 7 , wherein the TFR indicator is received via a downlink control information (DCI).

9. The one or more NTCRM of claim 1 , wherein the TFRS configuration information includes configuration information for only one time-frequency region.

10. One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors cause a next generation Node B (gNB) to:

encode, for transmission to a user equipment (UE), a radio resource control (RRC) message to indicate time-frequency resource set (TFRS) configuration information to be used for cancellation indication signaling; and

encode, for transmission to the UE, a cancellation indication to indicate, based on the TFRS configuration information, one or more time-frequency resources on which the UE is to cancel transmission of a physical uplink shared channel (PUSCH).

11. The one or more NTCRM of claim 10 , wherein the TFRS configuration information includes:

time-frequency information to define a time-frequency region for the cancellation indication signaling;

serving cell information to indicate one or more parameters for cancellation indication in a serving cell; and

message information to indicate one or more parameters for a downlink control information (DCI) message that includes the cancellation indication.

12. The one or more NTCRM of claim 11 , wherein the time-frequency information includes one or more of:

a starting symbol for the time-frequency region;

a time duration of the time-frequency region;

a time granularity of the time-frequency region; a frequency range of the time-frequency region; or

a number of frequency partitions in the time-frequency region.

13. The one or more NTCRM of claim 11 , wherein the serving cell information includes one or more of:

a serving cell ID of the serving cell;

a supplementary uplink (SUL) indicator to indicate whether the TFRS configuration information is for an SUL or a normal uplink carrier of the serving cell; or

a position indicator to indicate a location of a payload of the cancellation indication in an associated DCI.

14. The one or more NTCRM of claim 11 , wherein the message information includes:

a radio network temporary identifier (RNTI) to be used for the DCI; and

a payload size of the DCI.

15. The one or more NTCRM of claim 10 , wherein the instructions, when executed, further cause the gNB to encode, for transmission to the UE, a method indicator to indicate whether a cancellation indication method to be used is a dynamic method or a semi-static method.

16. The one or more NTCRM of claim 10 , wherein the TFRS configuration information includes configuration information for a plurality of time-frequency region (TFR) configurations, and wherein the instructions, when executed, further cause the gNB to receive a TFR indicator to indicate one of the TFR configurations that is to be used.

17. The one or more NTCRM of claim 16 , wherein the TFR indicator is transmitted via a downlink control information (DCI).

18. The one or more NTCRM of claim 10 , wherein the TFRS configuration information includes configuration information for only one time-frequency region.

19. The one or more NTCRM of claim 10 , wherein the UE is a first UE, and wherein the instructions, when executed, further cause the gNB to determine that a second UE is to perform an uplink transmission in the one or more time-frequency resources, wherein the cancellation indication is transmitted based on the determination.
