Abstract: A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, receiving configuration information indicating multiplexing between CG uplink control information (CG UCI) and hybrid automatic repeat request acknowledgement (HARQ-ACK) information, performing joint encoding of the CG UCI and the HARQ-ACK information based on the configuration information, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. The joint-encoded information is multiplexed in the CG PUSCH. A beta offset value corresponding to one of a first index, a second index, or a third index related to a beta offset for the HARQ-ACK information is applied to the joint encoding.

Abstract: Provided are a method for accessing a channel in an unlicensed band and a device using same method. The method is configured such that a wireless device transmits data units, receives feedback information about the data units, and adjusts a contention window size used in a determination of whether there is an access to the channel in the unlicensed band on the basis of the feedback information. The wireless device can adjust the contention window size by using feedback information about, from among the data units, data units which at least partially overlap in reference duration.
