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: The present disclosure provides a method for receiving a synchronization signal/physical broadcast channel (SS/PBCH) block by a terminal in an unlicensed band. Particularly, the method may comprise: receiving an SS/PBCH block including an SS and a PBCH; detecting an index of a demodulation reference signal (DMRS) sequence for the PBCH; and on the basis of the index of the DRMS sequence, acquiring information relating to a time when an index of the SS/PBCH block and the SS/PBCH block are received, wherein the number of indices of the SS/PBCH block is smaller than or equal to the number of indices of the DMRS sequence, and the indices of the SS/PBCH block are cyclically mapped to the indices of the DMRS sequence.

Abstract: Provided are a method and a device for reporting channel state information (CSI) in a wireless communication system. A wireless device receives a first uplink grant for indicating that a transmission of a physical uplink shared channel (PUSCH) is triggered by a second uplink grant in a first subframe on a Licensed-Assisted Access (LAA) cell. The first uplink grant requests a report of an aperiodic CSI. The wireless device computes the aperiodic CSI based on a valid subframe no later than the first subframe in which the first uplink grant is received.

Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when, as a result of performing the channel access procedure, it is determined that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal; receiving HARQ-ACK information corresponding to the transmission burst; and adjusting the CWS on the basis of the HARQ-ACK information corresponding to the first subframe of the transmission burst.
