1. A method for use in a wireless device, the method comprising:

  • a) transmitting a first radio resource control (RRC) message comprising a parameter indicating whether said wireless device supports an enhanced physical downlink control channel (ePDCCH);

    b) receiving, if said parameter indicates support of said ePDCCH, a second RRC message causing configuration of;

    i) first radio resources of a first ePDCCH comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said second RRC message indicating;

    (1) a starting OFDM symbol of said first ePDCCH in said subset of subframes; and

    (2) a configuration of said subset of subframes in which said first radio resources of said first ePDCCH are configured; and

    ii) second radio resources of a first data channel to start from said starting OFDM symbol in said subset of subframes; and

    c) receiving on said first ePDCCH scheduling information for a packet transmitted on said first data channel.
