Selectively multiplexing physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) communications

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

• memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols;
• determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication;
• selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time, wherein the UE does not multiplex the PUSCH communication and the PUCCH communication if at least one of the uplink grant, the downlink grant, or a last symbol of the PDSCH communication is received after the threshold time;
• and
• transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing.
