Abstract: The present discloser is related to a method, by a user equipment (UE), for transmitting uplink data through a preconfigured uplink resource (PUR) in a wireless communication system and a apparatus therefor. The UE receives, from a base station, PUR configuration information including a PUR transmission time, in an RRC connected state (radio resource control connected state), transitions from the RRC connected state to an RRC idle state, determines whether a timing advance (TA) related to uplink transmission timing is valid based on a reference signal received power (RSRP) change of a specific reference signal, wherein the RSRP change is a difference value between a first RSRP value measured based on point A and a second RSRP value measured based on point B, and transmits, to the base station, the uplink data at a first PUR transmission time based on the determination result and the PUR configuration information.

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.
