Claim 0:
1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
receiving first information regarding a plurality of groups, wherein the plurality of groups are respectively related to at least one search space set;
monitoring, based on the first information, a physical downlink control channel (PDCCH) according to at least one search space set related to one of the plurality of groups; and
based on first downlink control information (DCI) scheduling uplink transmission in an shared spectrum being obtained by monitoring the PDCCH:
(i) performing a channel access procedure (CAP) for the uplink transmission to access the shared spectrum, and
(ii) performing the uplink transmission based on the CAP;

wherein, based on second information related to a channel occupancy time (COT) being indicated by second DCI which is obtained by monitoring the PDCCH:
(i) monitoring the PDCCH according to at least one search space set related to a first group of the plurality of groups is started after the COT, and
(ii) monitoring the PDCCH according to the at least one search space set related to a second group of the plurality of groups is ended after the COT,

wherein the second DCI further indicates 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 based on a field related to the at least one available frequency resource included in the second DCI.
