1. A user equipment (UE), comprising:
a processor configured to:
configure physical uplink control channel (PUCCH) repetitions with a higher priority for a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback, the HARQ-ACK feedback being a feedback for a physical downlink shared channel (PDSCH), and
determine if there is a collision between the PUCCH repetitions with the higher priority for the HARQ-ACK feedback and more than one physical uplink channel, including a physical uplink shared channel (PUSCH), with a lower priority that starts earlier than the PUCCH repetitions with the higher priority; and
transmitting circuitry configured to transmit the HARQ-ACK feedback on the PUCCH repetitions with the higher priority, transmit the more than one physical uplink channel with the lower priority in non-overlapping symbols, and drop the more than one physical uplink channel with the lower priority in overlapping symbols, in a case that the collision occurs, wherein
the overlapping symbols are located over a plurality of slots, and
in each of the plurality of slots, a corresponding one of the PUCCH repetitions with the higher priority for the HARQ-ACK feedback is transmitted.
