Method for receiving downlink data channels in multicell-based wireless communication systems and apparatus for same

A method for transmitting a user equipment (UE)-specific reference signal based-downlink data channel at a base station in a wireless communication system, the method comprising:

• transmitting, by the base station, one or more configurations including information on a certain reference signal which is assumed to be quasi co-located with a UE-specific reference signal to a UE via an upper layer;
• transmitting, by the base station, scheduling information of the UE-specific reference signal based-downlink data channel to the UE;
• and
• transmitting, by the base station, the UE-specific reference signal based-downlink data channel to the UE which receives the UE-specific reference signal based-downlink data channel from the base station based on the scheduling information,
• wherein the scheduling information comprises an indicator indicating one of the one or more configurations, and
• wherein a large scale property for the UE-specific reference signal is obtained based on the certain reference signal which is assumed to be quasi co-located with the UE-specific reference signal.
