Abstract:
A user equipment (UE) and a base station (gNB) are described. The UE includes a higher layer processor configured to determine Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) feedback timing of HARQ-ACK feedback used for ultra-reliable low-latency communication (URLLC) physical downlink shared channel (PDSCH) transmissions. 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 at least one HARQ-ACK bit based on the HARQ-ACK feedback timing and the PUCCH resource. The gNB includes a higher layer processor configured to determine HARQ-ACK feedback timing of HARQ-ACK feedback used for PDSCH transmissions, and to determine a PUCCH resource for the HARQ-ACK feedback. The gNB also includes reception circuitry configured to receive at least one HARQ-ACK bit based on the HARQ-ACK feedback timing and the PUCCH resource.
