Dynamic repetition and frequency hopping factors for physical uplink control channel

A method of wireless communication performed by a base station, comprising:

• transmitting, to a user equipment (UE), radio resource control (RRC) signaling configuring a set of multiple physical uplink control channel (PUCCH) repetition factors or a set of multiple PUCCH frequency hopping factors;
• transmitting, to the UE, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) and indicating a PUCCH repetition factor, from among the set of multiple PUCCH repetition factors or a PUCCH frequency hopping factor from among the set of multiple PUCCH frequency hopping factors;
• and
• receiving, from the UE, a PUCCH comprising hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback associated with the PDSCH, wherein one or more instances of the PUCCH are received across one or more uplink slots or sub-slots based at least in part on the PUCCH repetition factor or the PUCCH frequency hopping factor, wherein a payload of an other PUCCH is multiplexed into the PUCCH received across the one or more uplink slots or sub-slots based at least in part on 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.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled with the one or more memories, configured to:
• receive, from a base station, radio resource control (RRC) signaling configuring a set of multiple physical uplink control channel (PUCCH) repetition factors or a set of multiple PUCCH frequency hopping factors;
• receive, from the base station, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) and indicating a PUCCH repetition factor, from among the set of multiple PUCCH repetition factors or a PUCCH frequency hopping factor from among the set of multiple PUCCH frequency hopping factors;
• transmit, to the base station, a PUCCH comprising hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback associated with the PDSCH, wherein 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 or the PUCCH frequency hopping factor;
• determine that another PUCCH that includes HARQ-ACK feedback associated with another PDSCH overlaps in time with the PUCCH;
• and
• multiplex a payload of the other PUCCH into the PUCCH transmitted across the one or more uplink slots or sub-slots based at least in part on the PUCCH transmitted across the one or more uplink slots or sub-slots having a higher priority than the other PUCCH, 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.
