CHANNEL DROPPING AND PROCESSING TIMING REQUIREMENTS FOR UPLINK CHANNEL COLLISION WITH DIFFERENT PRIORITIES

A user equipment (UE) is described. The UE includes a processor configured to determine a dropping timeline for low priority channel dropping when a low priority channel collides with a high priority physical uplink control channel (PUCCH) carrying a hybrid automatic repeat request-acknowledgement (HARQ-ACK). The processor is also configured to determine a processing delay for the high priority PUCCH when the low priority channel collides with the high PUCCH. The UE also includes transmitting circuitry configured to transmit the PUCCH carrying the HARQ-ACK based on the dropping timeline and the processing delay.
