Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus in which a terminal receives downlink data in a wireless communication system. The method comprises: a step of receiving a control channel signal including resource allocation information through a specific time domain of a subframe having a plurality of time domains; and a step of receiving the downlink data through the downlink data channel resource domain scheduled by the resource allocation information within said specific time domain. In cases where the downlink data channel resource domain is overlapped with a common search space, the downlink data is received through the residual resource domain except the portion overlapped with the common search space from among the downlink data channel resource domain.

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.

Abstract: Methods and devices for determining application delay value of a minimum scheduling offset restriction in a wireless communication system. The method accesses a specific base station through random access, and if DCI which includes information for notifying a change in the minimum scheduling offset restriction value in slot n of the scheduling cell is to be received from the base station, applies the changed minimum scheduling offset restriction value in slot n+X of the scheduling cell. The X value can be determined based on two parameters such as Y and Z, the Y value is the minimum scheduling offset restriction value to be applied to a scheduled cell scheduled by the DCI, and the Z value is predetermined according to the subcarrier spacing of the scheduling cell. The DCI can increase, by 1, the Z value according to the temporal position at which the DCI is received within slot n.
