A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.
