    Abstract: A method, performed by a user equipment (UE), for performing an initial access procedure in an unlicensed band includes: 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.

    Abstract: Provided are a method for adjusting a contention window size of a UE in a wireless communication system and the UE using the method. The method includes transmitting first data based on an AUL transmission to a BS, transmitting second data based on a grant-based uplink transmission to the BS, receiving first ACK/NACK information for the first data and second ACK/NACK information for the second data through an AUL-DFI, and adjusting the contention window size based on at least one of the first ACK/NACK information and the second ACK/NACK information included in the AUL-DFI. When the first data includes only one TB and the second data includes a plurality of TBs, the second ACK/NACK information is ACK if ACK/NACK for at least one of the plurality of TBs is ACK and the second ACK/NACK information is NACK if ACK/NACKs for all of the plurality of TBs are all NACKs.
