1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
obtaining information regarding groups, respectively related to at least one search space set, related to physical downlink control channel (PDCCH) monitoring, wherein the groups comprise a first group and a second group;
performing the PDCCH monitoring according to a search space set related to the second group based on the information regarding the groups;
based on first downlink control information (DCI) scheduling uplink transmission being received:
(i) performing a channel access procedure (CAP) for the uplink transmission in a shared spectrum; and
(ii) performing, based on the CAP, the uplink transmission in the shared spectrum, and wherein based on information related to a channel occupancy time (COT) being indicated by second DCI:
(i) the PDCCH monitoring according to a search space set related to the first group is started after the COT, and
(ii) the PDCCH monitoring according to the search space set related to the second group is ended after the COT,
wherein the second DCI comprises information related to at least one available frequency resource in the shared spectrum, and
wherein a total size of the at least one available frequency resource is an N multiple of a size of a frequency unit on which the CAP is performed, and N is a natural number.
