Methods and apparatuses for processing an acknowledgement report for reception of control information. A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs) includes determining a prioritization for receiving the PDCCHs and receiving the PDCCHs based on the prioritization. PDCCH receptions for a first search space set (SSS) are prioritized over PDCCH receptions for a second SSS or a third SSS. The PDCCH receptions for the second SSS are prioritized over the PDCCH receptions for the third SSS based on a configuration. The PDCCH receptions for the first SSS include a first downlink control information (DCI) format. The PDCCH receptions for the second SSS include a second DCI format that schedules a groupcast physical downlink shared channel (PDSCH) reception. The PDCCH receptions for the third SSS include a third DCI format that schedules a unicast PDSCH reception.
