Abstract: The present disclosure relates to a method and an apparatus of transmitting a hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK). A first set of HARQ-ACK/NACK including at least one timing value is identified. The at least one HARQ-ACK/NACK timing value is a time difference between a downlink time unit in which a physical downlink shared channel (PDSCH) is received and an uplink time unit in which a HARQ-ACK/NACK associated with the PDSCH is transmitted. A second set including at least one downlink time associated with a HARQ-ACK/NACK feedback is determined based on the first set. A codebook for the HARQ-ACK/NACK is generated based on a size of the codebook. The size of the codebook is identified based on the second set including the at least one downlink time. The codebook for the HARQ-ACK/NACK is transmitted to the base station in the uplink time unit.

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. The present disclosure discloses a method and an apparatus for data transmission. The method comprises: performing data transmission in a listen-before-talk mode; obtaining HARQ-ACK information of transmitted data bursts; and adjusting a contention window size CWS for carrier sensing to be performed before transmission of a next data burst based on HARQ-ACK information of reference data, wherein the reference data refers to a chosen PDSCH or PUSCH in a reference slot in a reference data burst selected from the transmitted data bursts. The method of the present disclosure may effectively reduce transmission collision between different nodes.
