1. A method for performing blind decoding in a wireless communication system, the method comprising:

  • performing, by a user equipment (UE), a first blind decoding in a cell-specific search space on a cell for detecting a Physical Downlink Control Channel (PDCCH);

    receiving, by the UE, a Radio Resource Control (RRC) message including information on a UE-specific search space, for monitoring an enhanced-PDCCH (EPDCCH) and identity information; and

    performing, by the UE, a second blind decoding in the UE-specific search on the cell for detecting the EPDCCH,wherein the PDCCH is demodulated based on a physical cell identity of the cell,wherein the EPDCCH is demodulated based on the identity information, andwherein the identity information used to demodulate the EPDCCH is different from the physical cell identity used to demodulate the PDCCH.
