1. A method for receiving an enhanced physical downlink control channel (E-PDCCH) in a data region of a downlink subframe by a user equipment (UE) in a wireless communication system, the method comprising the step of: detecting the E-PDCCH by performing blind decoding of a plurality of E-PDCCH candidates included in a search space for the E-PDCCH, wherein the blind decoding is performed in accordance with an order of priority given to each of a plurality of sub-search spaces constituting the search space, and wherein the order of priority is determined based on downlink transmission information including at least one of a transmission data rate of a physical downlink shared channel (PDSCH) indicated by the E-PDCCH, a payload size of the PDSCH, a transmission modulation order of the PDSCH, and the number of resource blocks allocated to the PDSCH.
