1. A method, performed by a user equipment (UE), of obtaining channel occupancy time information, the method comprising:
receiving a higher layer signaling;
detecting downlink control information (DCI), based on at least one of configuration information of a control resource set (CORESET) and configuration information of a search space set included in the higher layer signaling;
identifying slot format indicator (SFI) information included in the DCI, wherein the SFI information comprises a slot format combination identifier indicating slot formats of slots corresponding to a channel occupancy time starting from a slot in which the DCI including the SFI information is detected; and
identifying the channel occupancy time of a base station (BS), based on a number of slots whose slot format is indicated by the SFI information.
