Downlink control channel signaling for uplink coexistance of multiple service types

1. Baseband circuitry, configured to:

receive a configuration signaling to monitor for uplink (UL) cancellation indications;

monitor, based on the configuration signaling, a search space for an UL cancellation indication;

detect an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and

in response, cancel UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission.

2. The baseband circuitry of claim 1 , wherein the scheduled PUSCH transmission is associated with a Type 1 or Type 2 configured grant.

3. The baseband circuitry of claim 1 , wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions.

4. The baseband circuitry of claim 1 , further configured to monitor for UL cancellation indications in a group-common search space associated with a Control Resource Set (CORESET).

5. The baseband circuitry of claim 1 , further configured to:

cancel a portion of the scheduled PUSCH transmission specified by the UL cancellation indication.

6. The baseband circuitry of claim 1 , further configured to:

cancel all scheduled UL transmissions that overlap with physical resources specified by the UL cancellation indication.

7. The baseband circuitry of claim 1 , further configured to:

detect that a trigger condition has been met; and

in response, commence monitoring of the search space for cancellation indications.

8. The baseband circuitry of claim 7 , further configured to detect that the trigger condition has been met when an UL grant for scheduling a PUSCH transmission is received.

9. The baseband circuitry of claim 1 , further configured to:

receive a second UL grant for a transport block (TB) associated with a scheduled UL transmission resulting from a first UL grant; and

in response, cancel the scheduled UL transmission.

10. The baseband circuitry of claim 9 , further configured to cause transmission of the TB according to the second UL grant.

11. The baseband circuitry of claim 9 further configured to determine that the second UL grant and the first UL grant have a same hybrid automatic repeat request (HARQ) process identifier associated with the TB, and in response, cancel the scheduled UL transmission.

12. The baseband circuitry of claim 1 , further configured to:

determine a length of the scheduled PUSCH transmission; and

refrain from monitoring the search space when the length falls below a threshold.

13. The baseband circuitry of claim 1 , further configured to:

transmit a portion of the scheduled PUSCH transmission that does not overlap with physical resources specified by the UL cancellation indication.

14. The baseband circuitry of claim 1 , further configured to:

receive an UL grant;

schedule the PUSCH transmission based on the UL grant;

determine, based on the UL grant, that the UL grant is prioritized; and

receiving the UL cancellation indication for the scheduled PUSCH transmission; and

cause transmission of the scheduled PUSCH transmission.

15. The baseband circuitry of claim 14 , further configured to, in response to receiving the UL cancellation indication, cancel a subsequent scheduled repeat UL transmission that resulted from the UL grant.

16. The baseband circuitry of claim 14 , further configured to determine that the UL grant is prioritized based on a value of a DCI field of the UL grant.

17. A user equipment, comprising a memory and a baseband processor configured to, when executing instructions stored in the memory, cause the UE to receive a configuration signaling to monitor for uplink (UL) cancellation indications;

monitor, based on the configuration signaling, a search space for an UL cancellation indication;

detect an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and

in response, cancel UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission.

18. The UE of claim 17 , wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions.

19. A method, comprising:

receiving a configuration signaling to monitor for uplink (UL) cancellation indications;

monitoring, based on the configuration signaling, a search space for an UL cancellation indication;

detecting an UL cancellation indication in the search space, wherein the UL cancellation indication identifies physical resources that span beyond a scheduled physical uplink shared channel (PUSCH) transmission; and

in response, canceling UL transmissions that overlap with the physical resources identified by the UL cancellation indication including at least a portion of the scheduled PUSCH transmission.

20. The method of claim 19 , wherein the UL cancellation indication comprises an X by Y bitmap of physical resources, wherein X is greater than one and corresponds to a number of time partitions and Y is greater than one and corresponds to a number of frequency partitions.
