Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A base station comprising:
a transceiver configured to transmit information for first, second, and third search space sets (SSSs), wherein the information includes respective identities of the SSSs; and
a processor operably connected to the transceiver, the processor configured to determine a prioritization for transmission of physical downlink control channels (PDCCHs), wherein:
PDCCH transmissions for the first SSS are prioritized over PDCCH transmissions for the second SSS and PDCCH transmissions for the third SSS independent of the respective identities,
the PDCCH transmissions for the second SSS are prioritized or deprioritized over PDCCH transmissions for the third SSS based on the respective identities a configuration,
the PDCCH transmissions for the first SSS are according to a first common search space (CSS) and include a first downlink control information (DCI) format,
the PDCCH transmissions for the second SSS are according to a second CSS and include a second DCI format that schedules a groupcast physical downlink shared channel (PDSCH) transmission, and
the PDCCH transmissions for the third SSS are according to a UE-specific search space (USS) and include a third DCI format that schedules a unicast PDSCH transmission; and

wherein the transceiver is further configured to transmit the PDCCHs based on the prioritization.
