摘要： The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT. A method of a base station includes determining a contention window for a sub-band among multiple sub-bands based on hybrid automatic repeat request-acknowledgement feedbacks corresponding to physical downlink shared channels (PDSCHs) in a reference duration, identifying a number for the sub-band between zero and the contention window, sensing the sub-band based on the number and a defer duration, and performing a downlink transmission based on sensing the sub-band to be idle, wherein the reference duration starts from a beginning of a channel occupancy and ends at a first slot where at least one of the PDSCHs is transmitted, and wherein the PDSCHs in the reference duration include a PDSCH that partially but not fully overlaps with the sub-band among the multiple sub-bands and a PDSCH that fully overlaps with the sub-band among the multiple sub-bands.

摘要： Methods and apparatuses are provided for performing communication in a wireless communication system is provided. A number of hybrid automatic repeat request (HARQ) processes is set as N. The N is a natural number, one value within a maximum value, 16, and set based on a configuration of a base station (BS). Downlink control information (DCI) is received including a 1-bit HARQ-acknowledgment (HARQ-ACK) feedback request for all of N HARQ processes. HARQ-ACK information associated with all of the N HARQ processes is identified, based on the received DCI. A number of bits for the HARQ-ACK information is defined based on xN by the configuration, and the x is a natural number. The HARQ-ACK information is transmitted to the BS.
