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: According to an embodiment of the present disclosure, a user equipment (UE) may receive a first synchronization signal block (SSB) among a plurality of SSBs, receive information on one or more group radio network temporary identifiers (G-RNTIs) through higher layer signaling, and receive a physical downlink control channel (PDCCH) based on the first SSB and the one or more G-RNTIs. The PDCCH received by the UE may be a PDCCH for a multicast broadcast service (MBS) associated with a first G-RNTI selected from among the one or more G-RNTIs, and the PDCCH for the MBS associated with the first G-RNTI may be repeated for each of the plurality of SSBs. In this case, the number of repetitions of the PDCCH for the MBS for each SSB may be determined based on information configured for the first G-RNTI.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may obtain fixed frame period (FFP)-related information, and perform clear channel assessment (CCA) for at least one FFP starting with a UE-initiated channel occupancy time (COT) for transmission of an uplink signal. The FFP-related information may include information about an FFP starting offset and information about an FFP duration or period, and the UE may identify a starting time of the FFP, based on the FFP starting offset having an orthogonal frequency division multiplexing (OFDM) symbol-level granularity.
