1. An apparatus comprising:

  • a communications module configured to communicate with a user equipment (UE) over a wireless communication network via a plurality of antenna ports;

    a control module configured to generate an enhanced physical downlink control channel (ePDCCH); and

    a mapping module coupled with the control module and the communications module and configured to;

    map individual enhanced control channel elements (eCCEs) of a physical resource block (PRB) pair including a plurality of eCCEs to a plurality of non-continuous enhanced resource element groups (eREGs) of the PRB pair;

    map the plurality of eREGs to individual antenna ports for transmission to the UE, wherein individual antenna ports are associated with a continuous group of eREGs; and

    assign at least a portion of the ePDCCH to one or more of the eCCEs for transmission to the UE.
