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.
