1. A method for receiving, by a user equipment (UE), one or more physical downlink control channels (PDCCHs) from a wireless network using a selectable portion of a plurality of available resources, the method comprising the UE:
determining one or more PDCCH reception quality metrics for each of a plurality of candidate subsets of the available resources;
selecting a particular candidate subset out of the plurality of candidate subsets based on the determined PDCCH reception quality metrics; and
monitoring for PDCCH transmissions using only the selected subset of resources, wherein:
verifying a CRC field comprises verifying the CRC field in each received first PDCCH transmission a plurality of times, with each verification of the CRC field being associated with a different amount of degradation of the received PDCCH transmission; and
determining the PDCCH reception quality metric for each first PDCCH transmission comprises selecting the maximum amount of degradation under which the verification of the CRC field is successful.
