Disclosed are a method and a device for applying a time offset between downlink reception (or downlink transmission) and uplink transmission (or uplink reception) in a wireless communication system. A method for performing uplink transmission by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving a timing offset related to uplink transmission, from a base station via system information; receiving a downlink channel from the base station in a first time unit; and transmitting an uplink channel to the base station in a second time unit. The number of time units between the first time unit and the second time unit may be based on a first time offset or a second time offset. The first time offset may be based on base offset information and additional offset information, and the second time offset may be based on the base offset information. The base offset information may be obtained via downlink control information (DCI) related to the downlink channel. A size of a field indicating the base offset in the DCI may be the same for the first time offset and the second time offset.
