Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present application provide a method and device for transmitting Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK). The method for transmitting HARQ-ACK comprises: receiving, in a downlink time unit, a physical downlink shared channel (PDSCH) and control signaling, which are transmitted by a transmitting side; determining, according to the control signaling, an uplink time unit configured to feed back HARQ-ACK corresponding to the received PDSCH and an HARQ-ACK codebook corresponding to the uplink time unit; and transmitting HARQ-ACK information corresponding to the HARQ-ACK codebook on a physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) in the uplink time unit. By the method of the present application, the determination of an HARQ-ACK codebook corresponding to an uplink time unit is realized, and thus the effective utilization of uplink control channel resources is ensured.
