1. A method for detecting uplink control information on a component carrier configured as a serving cell, comprising:

  • receiving, at an evolved Node B (eNodeB), a message 1 pertaining to a Random Access CHannel (RACH) communication from a User Equipment (UE);

    identifying a Cell-Radio Network Temporary Identifier (C-RNTI) pertaining to the UE to receive a Downlink Control Information (DCI) message including resource allocation information for a message 2 associated with the RACH communication; and

    sending the DCI message in at least one channel control element in a UE Specific Search Space (USS) within a Physical Downlink Control CHannel (PDCCH) search space of at least one sub-frame transmitted by the eNodeB, wherein the DCI message is configured with a Cyclic Redundancy Check (CRC), wherein the CRC is configured not to produce a CRC error during blind decoding performed by applying the C-RNTI to the DCI message.
