1. A method for receiving physical downlink control channels (PDCCHs), the method comprising:
receiving information for scheduling on a primary cell from the primary cell and from a secondary cell;
identifying a number of PDCCH candidates on the primary cell in a slot and a number of non-overlapping control channel elements (CCEs) on the primary cell in the slot based on the information;
identifying, for scheduling on the primary cell from the primary cell, that at least one of:
the number of PDCCH candidates exceeds a first number of PDCCH candidates, and
the number of non-overlapping CCEs exceeds a first number of non-overlapping CCEs;
canceling PDCCH receptions corresponding to UE-specific search space (USS) sets for scheduling on the primary cell from the primary cell; and
receiving all PDCCHs for scheduling on the primary cell from the secondary cell,
wherein PDCCH candidates on the primary cell are with a first subcarrier spacing (SCS) configuration,
wherein PDCCH candidates on the secondary cell are with a second SCS configuration, and
wherein the slot corresponds to a smaller of the first SCS and the second SCS.
