Classification: CPC H  Y | IPC H

Claim 7:
8. A base station comprising:
a transceiver configured to transmit:
a configuration for a set of search space sets, wherein a search space set provides parameters for physical downlink control channel (PDCCH) transmissions and wherein the parameters include:
time-frequency resources of a control resource set (CORESET) for the PDCCH transmissions, and
a group index for the CORESET, and

a PDCCH that provides a downlink control information (DCI) format, wherein the DCI format includes a field providing an indication of a CORESET group index; and

a processor operably coupled to the transceiver, the processor configured to determine a group of search space sets in which to transmit PDCCHs and to indicate via the indication, wherein the group of search space sets includes each search space set from the set of search space sets that is associated with a CORESET having the CORESET group index, and
wherein the transceiver is further configured to transmit the PDCCHs according to the group of search space sets.
