Claim 21:
22. A user equipment (UE) configured to receive a physical downlink control channel (PDCCH) from a radio access network (RAN) using a selectable number of available antennas and receive chains, the UE comprising:
transceiver circuitry configured to communicate with a RAN node, the transceiver circuitry including the available antennas and receive chains; and
processing circuitry operatively coupled to the transceiver circuitry, whereby the processing circuitry and the transceiver circuitry are configured to:
receive, from the RAN node, a PDCCH configuration;
select a number of antennas and receive chains to be activated for receiving PDCCH from the RAN node, based on one or more of the following included in the PDCCH configuration:
a search space comprising a plurality of PDCCH candidates;
a format of downlink control information (DCI) messages transmitted on the PDCCH; and
at least one slot offset between a PDCCH transmission and a subsequent transmission of a physical downlink shared channel (PDSCH); and

receive, from the RAN node, one or more PDCCHs using the selected number of antennas and receive chains.
