    Abstract: A method by which a terminal measures channel state information (CSI) in an unlicensed band is disclosed. Particularly, the method comprises: receiving at least one channel state information-reference signal (CSI-RS) through at least one listen before talk (LBT) sub-band of a plurality of LBT sub-bands for transmitting a plurality of CSI-RSs within one transmit opportunity (TxOP) section; determining each measurement use for at least one CSI-RS; and measuring the CSI on the basis of each measurement use for the at least one determined CSI-RS, wherein the determination of each measurement use for the at least one CSI-RS is the determining of whether the CSI-RS is for an interference measurement or the CSI-RS is for a signal measurement.

    Abstract: A method and a device for performing uplink transmission or reception in a wireless communication system are disclosed. A method for performing uplink transmission by a terminal according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, configuration information including N1 pieces of first information related to unicast SPS transmission and N2 pieces of second information related to multicast SPS transmission; and transmitting, to the base station, first HARQ-ACK information associated with N1 pieces of unicast SPS transmissions and second HARQ-ACK information related to N2 pieces of multicast SPS transmissions, the first and second HARQ-ACK information being multiplexed on a first PUCCH, wherein the first HARQ-ACK information and the second HARQ-ACK information are multiplexed on the first PUCCH on the basis of the ascending order of the indexes of the N1 pieces of first information and the N2 pieces of second information.

    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.
