    Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.

    Abstract: Disclosed herein is a terminal configured to acquire a configuration for at least one PUCCH resource set associated with at least one downlink multicast channel, monitor a PDCCH in a search space for scheduling of a specific downlink multicast channel, and detect, as a result of the monitoring of the PDCCH, DCI having a CRC scrambled with a specific G-RNTI, wherein a specific PUCCH resource set associated with the specific downlink multicast channel may be mapped to a specific downlink frequency band having the search space for the monitoring of the PDCCH, wherein a PUCCH resource for transmission of HARQ-ACK for the specific downlink multicast channel among one or more PUCCH resources included in the specific PUCCH resource set may be indicated through the DCI.
