Claim:
1. A method of receiving a user equipment (UE)-specific reference signal based-downlink data channel by a UE in a wireless communication system, the method comprising: receiving information on one or more configurations defining a large scale property of a UE-specific reference signal from a network via an upper layer; detecting either first scheduling information or second scheduling information for the UE-specific reference signal based-downlink data channel from the network; and receiving the UE-specific reference signal based-downlink data channel based on the detected scheduling information, wherein the first scheduling information comprises an indicator indicating one of the one or more configurations, wherein the large scale property of the UE-specific reference signal is defined according to a configuration indicated by the indicator when the first scheduling information is detected and is defined according to a predetermined configuration among the one or more configurations when the second scheduling information is detected, and wherein the predetermined configuration corresponds to a configuration of a minimum index among the one or more configurations.
