Abstract
A user equipment (UE) is described. The UE includes a higher layer processor configured to determine HARQ-ACK feedback timing for HARQ-ACK feedback of ultra-reliable low-latency communication (URLLC) physical downlink shared channel (PDSCH) transmissions with a subslot structure. The higher layer processor is also configured to determine a physical uplink control channel (PUCCH) resource for the HARQ-ACK feedback. The UE also includes transmitting circuitry configured to transmit the HARQ-ACK feedback for the URLLC PDSCH transmissions based on the HARQ-ACK feedback timing and the PUCCH resource.
