Claim:
1. A method for monitoring downlink control information (DCI) by a user equipment (UE) in a wireless communication system, the method comprising: receiving configuration information, wherein the configuration information specifies subframes in which the UE monitors an enhanced physical downlink control channel (EPDCCH) associated with a serving cell; and monitoring the EPDCCH in the specified subframes based on the configuration information, wherein each of the specified subframes comprises a common search space (CSS) and a user equipment specific search space (USS), wherein, in each of the specified subframes, the UE monitors a plurality of DCI formats on the EPDCCH located in the USS based on the configuration information, and monitors at least one DCI format among the plurality of DCI formats on the PDCCH located in the CSS, and wherein the at least one DCI format is DCI format 0 which is used for scheduling a physical uplink shared channel (PUSCH) or DCI format 1A which is used for scheduling a physical downlink shared channel (PDSCH).
