1. A method for a user equipment (UE) to monitor a physical downlink control channel (PDCCH) for carrier aggregation (CA), the method comprising:
receiving PDCCH candidates from a plurality of configured downlink (DL) cells;
in response to a determination that a maximum number of DL cells that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured DL cells, grouping the plurality of configured DL cells into groups based at least in part on subcarrier spacing (SCS) and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe;
determining a maximum number of blind decoding (BD) operations and non-overlapped control channel elements (CCEs) for each of the groups; and
monitoring at least a first portion of the PDCCH candidates based on the maximum number of BD operations and non-overlapped CCEs for each of the groups.
