Claim:
1. A method for receiving, by a user equipment, a downlink signal from a base station, the method comprising: detecting a physical downlink control channel (PDCCH) by blind decoding a plurality of PDCCH candidates according to only a predetermined downlink control information (DCI) format independent of a transmission mode of the user equipment within a PDCCH search space located in a control region of a first subframe, where the first subframe is divided into the control region and a data region in a time domain, and the control region is located at a front of the first subframe in the time domain; detecting an enhanced PDCCH (EPDCCH) by blind decoding a plurality of EPDCCH candidates according to only a transmission mode dependent DCI format (TM DCI format) corresponding to the transmission mode of the user equipment within an EPDCCH search space located in the data region of the first subframe based on the PDCCH; and receiving a physical downlink shared channel (PDSCH) in a data region of a second subframe based on the EPDCCH, wherein the PDCCH carries configuration information of the EPDCCH search space, and wherein the first subframe, in which the EPDCCH is detected, precedes the second subframe, in which the PDSCH is received based on the EPDCCH, in the time domain.
