1. A method for use in a base station, the method comprising:

  • a) transmitting on a Physical Downlink Control Channel (PDCCH), to a wireless device, first scheduling information for a radio resource control (RRC) message, first radio resources of said PDCCH in a subframe in a plurality of subframes starting from the first OFDM symbol of said subframe;

    b) transmitting, to said wireless device, said RRC message comprising configuration parameters of second radio resources of an enhanced PDCCH (ePDCCH), said second radio resources comprising one or more resource blocks in a subset of subframes in said plurality of subframes, said RRC message indicating;

    i) said subset of subframes;

    ii) a first starting OFDM symbol of both said ePDCCH and a data channel in said subset of subframes; and

    iii) frequency resources for said ePDCCH in terms of resource blocks in said subset of subframes; and

    c) transmitting, to said wireless device, second scheduling information on said ePDCCH for a packet transmitted on said data channel.
