selecting a PDCCH configuration including the following parameters, wherein at least one of the following is selected to facilitate the UE using a reduced number of antennas and receive chains for PDCCH reception:
a search space comprising a plurality of PDCCH candidates;
a downlink control information (DCI) format; and
at least one slot offset between PDCCH transmission and a subsequent transmission of a physical downlink shared channel (PDSCH);
