1. A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs), the method comprising:
receiving information for first, second, and third search space sets (SSSs), wherein the information includes respective identities of the SSSs; and
determining a prioritization for receiving the PDCCHs, wherein:
PDCCH receptions for the first SSS are prioritized over PDCCH receptions for the second SSS and PDCCH receptions for the third SSS independent of the respective identities,
the PDCCH receptions for the second SSS are prioritized or deprioritized over the PDCCH receptions for the third SSS based on the respective identities,
the PDCCH receptions for the first SSS are according to a first common search space (CSS) and include a first downlink control information (DCI) format,
the PDCCH receptions 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) reception, and
the PDCCH receptions for the third SSS are according to a UE-specific search space (USS) and include a third DCI format that schedules a unicast PDSCH reception; and
receiving the PDCCHs based on the prioritization.
