1. A method for receiving physical downlink control channels (PDCCHs), the method comprising:
receiving first information for first search space sets associated with receptions of first PDCCHs on a first scheduling cell, wherein:
the first PDCCHs have subcarrier spacing (SCS) configuration μ1,
a first PDCCH from the first PDCCHs provides a first downlink control information (DCI) format,
the first DCI format schedules a first physical downlink shared channel (PDSCH) reception or a first physical uplink shared channel (PUSCH) transmission on a scheduled cell, and
the first DCI format is from a first set of DCI formats;
receiving second information for second search space sets associated with receptions of second PDCCHs on a second scheduling cell, wherein:
the second PDCCHs have SCS configuration μ2,
a second PDCCH from the second PDCCHs provides a second DCI format,
the second DCI format schedules a second PDSCH reception or a second PUSCH transmission on the scheduled cell, and
the second DCI format is from a second set of DCI formats, wherein the second set of DCI formats is different from the first set of DCI formats; and
determining:
a first number of scheduled cells associated with scheduling cells having PDCCH receptions with SCS configuration μ1, wherein, when μ1=μ2, the scheduled cell is counted once towards the first number of scheduled cells, and
a second number of scheduled cells associated with scheduled cells having PDCCH receptions with SCS configuration μ2 wherein, when μ1<μ2, the scheduled cell is counted once towards a sum of:
the first number of scheduled cells, and
the second number of scheduled cells.
