Abstract: Disclosed, in the present invention, are a method for transmitting, by a base station, a downlink signal in a wireless communication system supporting an unlicensed band, and a device for supporting the same. More particularly, in accordance with one embodiment of the present invention, when acknowledgment timing of each terminal (for example, an interval length from a time point of receiving downlink data to a time point of transmitting acknowledgment information for the downlink data) is set flexibly (or independently), a base station may determine a reference downlink resource for contention window size (CWS) adjustment by considering the acknowledgement timing and perform downlink signal transmission by adjusting CWS on the basis of the acknowledgment information received for the reference downlink resource.

Abstract: Disclosed is a method for transmitting an uplink signal to a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: detecting a downlink control signal from the base station through a terminal-specific search space or a common search space at a first time point; and transmitting an uplink signal corresponding to the downlink control signal to the base station on the basis of the downlink control signal, wherein, when the downlink control signal is detected in the terminal-specific search space, the uplink signal is transmitted at a second time point, and when the downlink control signal is detected in the common search space, the uplink signal is transmitted at a third time point.
