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.
A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver,
- wherein the at least one processor is configured to:
- receive first information regarding a plurality of groups, wherein the plurality of groups are respectively related to at least one search space set;
- monitor, 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;
- based on first downlink control information (DCI) scheduling uplink transmission in an shared spectrum being obtained by monitoring the PDCCH:
- (i) perform a channel access procedure (CAP) for the uplink transmission to access the shared spectrum, and
- (ii) perform 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) monitor 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) monitor 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.
A method performed by a base station (BS) configured to operate in a wireless communication system, the method comprising:
- transmitting first information regarding a plurality of groups, wherein the plurality of groups are respectively related to at least one search space set;
- transmitting, 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 downlink transmission in an shared spectrum being transmitted through the PDCCH:
- (i) performing a channel access procedure (CAP) for the downlink transmission to access the shared spectrum, and
- (ii) performing the downlink transmission based on the CAP;
- wherein, based on second information related to a channel occupancy time (COT) being indicated by second DCI which is transmitted through the PDCCH:
- (i) transmitting 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) transmitting 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.
A base station (BS) configured to operate in a wireless communication system, the BS comprising:
- a transceiver;
