Claim Text:
1. A method for receiving downlink signals in a wireless communication system, the method comprising: receiving downlink signal from a base station and detecting the downlink signal, wherein the detecting the downlink signal includes, if the number of resource elements (REs) to which channel state information-reference signal (CSI-RS) in a downlink subframe is mapped is smaller than the number of the enhanced control channel elements (eCCEs) for an enhanced physical downlink control channel (EPDCCH) in the downlink subframe, assuming REs, the number of which corresponds to a difference value between the number of eCCEs and the number of REs, which are included in the EPDCCH, as a zero-power CSI-RS, and wherein the REs assumed as the zero-power CSI-RS is included in an eCCE that does not comprise the REs to which the CSI-RS is mapped.
