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.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.
