1. A method performed by a network device, the method comprising:
determining a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to at least one physical downlink shared channel (PDSCH) transmission in a reference duration for which the HARQ-ACK feedback is available; and
performing contention window adjustment based on the HARQ-ACK feedback,
wherein the reference duration comprises at least one first PDSCH transmission transmitted over all allocated resources, or the reference duration comprises at least one second PDSCH transmission transmitted not over all the allocated resources, and
wherein the reference duration comprises the at least one second PDSCH transmission transmitted not over all the allocated resources, in a case where the reference duration does not include any PDSCH transmission transmitted over all the allocated resources.
