1. A method comprising:

  • (a) receiving a first high-layer information from a base station by a user equipment (UE) to determine a first set of physical resource blocks (PRBs);

    (b) determining a first set of candidate enhanced physical downlink control channel (ePDCCHs) within the first set of PRBs, wherein one or a plurality of candidate ePDCCHs potentially carries downlink control information intended for the UE;

    (c) decoding the first set of candidate ePDCCHs to obtain the downlink control information intended for the UE;

    (d) receiving a second high-layer information from the base station by the UE to determine a second set of PRBs, wherein the second high-layer information is different from the first high-layer information;

    (e) determining a second set of candidate ePDCCHs within the second set of PRBs, wherein one or a plurality of candidate ePDCCHs potentially carries the downlink control information intended for the UE; and

    (f) decoding the second set of candidate ePDCCHs to obtain the downlink control information intended for the UE.
