Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) and indicating a physical uplink control channel (PUCCH) repetition factor. The UE may transmit, and the base station may receive, a PUCCH that includes hybrid automatic repeat request acknowledgement feedback associated with the PDSCH. In some aspects, one or more instances of the PUCCH are transmitted across one or more uplink slots or sub-slots based at least in part on the PUCCH repetition factor indicated in the DCI. Numerous other aspects are provided.

3. The method of claim 1 ,

wherein the DCI includes one or more bits to indicate the PUCCH repetition factor among the set of multiple PUCCH repetition factors.

4. The method of claim 1 , wherein the one or more instances of the PUCCH are transmitted in one or more frequencies across the one or more uplink slots or sub-slots based at least in part on the PUCCH frequency hopping factor indicated in the DCI.

9. The method of claim 8 , wherein the PUCCH transmitted across the one or more uplink slots or sub-slots has the higher priority based at least in part on the PUCCH having an earlier transmission time than the other PUCCH.

10. The method of claim 8 , wherein the PUCCH transmitted across the one or more uplink slots or sub-slots has the higher priority based at least in part on the PUCCH having a larger PUCCH repetition factor than the other PUCCH.

11. The method of claim 8 , wherein the PUCCH transmitted across the one or more uplink slots or sub-slots has the higher priority based at least in part on the DCI scheduling the PUCCH being received more recently than DCI scheduling the other PUCCH.

12. The method of claim 8 , wherein the PUCCH transmitted across the one or more uplink slots or sub-slots has the higher priority based at least in part on the PUCCH having a larger frequency hopping factor than the other PUCCH.

13. The method of claim 8 , wherein the payload of the other PUCCH is multiplexed into the PUCCH transmitted across the one or more uplink slots or sub-slots based at least in part on the UE receiving the DCI scheduling the PDSCH and the UE receiving another DCI scheduling the other PUCCH more than a threshold time prior to the one or more uplink slots or sub-slots in which the PUCCH is transmitted.

14. The method of claim 8 , wherein the payload of the other PUCCH is multiplexed into the PUCCH transmitted across the one or more uplink slots or sub-slots based at least in part on the UE receiving the PDSCH scheduled by the DCI and the UE receiving the other PDSCH more than a threshold time prior to the one or more uplink slots or sub-slots in which the PUCCH is transmitted.
