Abstract
The present invention relates to a method and a device for a channel access procedure in a wireless communication system. More specifically, the present invention relates to a method for performing a channel access procedure by a base station in a specific direction (or beam) in an unlicensed band. More specifically, the present invention proposes a method for configuring and generating downlink control information by a base station in order to transmit, to a terminal, a result of a channel access procedure performed in a specific direction, and a method for determining the information by the terminal. A method of a terminal in a communication system according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, downlink control information (DCI) for scheduling of uplink signal transmission; checking beam-related information which is included in the DCI and indicates a beam for the uplink signal transmission; and performing the uplink signal transmission to the base station without a channel access procedure of the terminal on the basis of the beam indicated by the beam-related information.
