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.
