The present invention relates to a wireless communication system. A method for receiving data by a user equipment (UE) in a cooperative multi-point (CoMP) wireless communication system includes receiving downlink control information (DCI) that does not contain information indicating a transmission base station (BS) that actually transmits data among a plurality of BSs that participate in CoMP, receiving information about zero-power channel state information-reference signal (CSI-RS) of each of the plural BSs, and assuming that data is not mapped to a resource element of zero-power CSI-RS with a lowest index and receiving the data through a physical downlink control channel (PDSCH).
