Abstract: The present disclosure provides a method, performed by a user equipment (UE), for performing an initial access procedure in an unlicensed band, the method comprising: performing the initial access procedure with a base station; and performing transmission of a physical uplink shared channel (PUSCH) on the basis of the performing of the initial access procedure, wherein the UE obtains, from the base station, information about a listen before talk (LBT) type and information about a PUSCH starting position, and the UE performs the transmission of the PUSCH on the basis of the information about the LBT type and the information about the PUSCH starting position. The information about the PUSCH starting position is information indicating one position among a plurality of PUSCH starting position candidates. The information about the LBT type indicates one of a LBT type 1, a LBT type 2, and a LBT type 3. The UE performs random backoff-based LBT in the LBT type 1, the UE performs LBT without a random backoff in the LBT type 2, and the UE does not perform LBT in the LBT type 3.

Abstract: Disclosed is a method for a terminal to perform uplink (UL) transmission in a wireless communication system. In particular, the method comprises the steps in which a base station: receives information related to a sensing beam used for initiating channel occupancy time (COT); determines, on the basis of a quasi co-located (QCL) relationship between the sensing beam and the UL transmission, whether COT sharing is available; on the basis that the COT sharing is not available, senses a channel corresponding to the UL transmission on the basis of a type 1 channel access procedure (CAP) and performs the UL transmission on the basis of the channel being sensed as IDLE; and on the basis that the COT sharing is available, senses the channel on the basis of a type 2 CAP and performs the UL transmission within the COT on the basis of the channel being sensed as IDLE.

Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) in a band equal to or higher than 52.6 GHz in a wireless communication system. Specifically, the method may comprise: receiving a system information block (SIB); receiving a random access response (RAR) uplink (UL) grant for scheduling the PUSCH; and transmitting the PUSCH on the basis of the RAR UL grant, wherein, on the basis that the SIB includes a parameter indicating that a channel access procedure (CAP) should be applied, the number of bits of a field for indicating a channel access type included in the RAR UL grant is 2, and on the basis that the SIB does not include the parameter, the number of bits of a field for indicating the channel access type included in the RAR UL grant is 0.
