Abstract: A method by which a terminal transmits an uplink signal in an unlicensed band, and an apparatus using same are provided. The method receives, from a base station, channel occupancy information through a PDCCH and transmits the uplink signal to the base station through a configured grant uplink access (CUL) type physical uplink shared channel (PUSCH) on the basis of the channel occupancy information. The channel occupancy information indicates which sub-band of a CUL band including a plurality of sub-bands enables the terminal to transmit the CUL type PUSCH within a channel occupancy time (COT) acquired by the base station through a channel access procedure.
