Abstract: The present invention discloses a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal and a device for the same. Specifically, a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal includes: detecting a specific synchronization signal received from a base station via a first symbol of a first subframe; detecting the specific synchronization signal received from the base station via a second symbol of a second subframe; and obtaining information for the CP applied to transmission of the specific synchronization signal based on an offset value between an index of the first symbol and an index of the second symbol.

Abstract: The present invention relates to a radio access system that supports an unlicensed band, and provides methods for controlling a contention window size (CWS) for performing uplink LBT, methods for effectively utilizing a radio resource even when an uplink data transmission fails, and apparatuses supporting the same. As an embodiment of the present invention, a method for controlling a contention window size (CWS) for transmitting uplink data in a radio access system supporting an unlicensed band by a user equipment, may comprise the steps of: receiving, from an evolved node B, a radio signal including CSW control information indicating information required for controlling a CWS; controlling the CWS on the basis of the CWS control information; performing a listen before talk (LBT) process using the controlled CWS; and transmitting uplink data when a result of the LBT process shows that an unlicensed band is in an idle state.
