The present invention relates to a method by which a terminal receives a downlink data channel in a wireless communication system. In detail, the method includes the steps of receiving from a network information on one or more settings defining large scale properties of a terminal-specific reference signal through a higher layer; detecting from the network one of either the first scheduling information or the second scheduling information on a downlink data channel based on a terminal-specific reference signal; and receiving the downlink data channel based on the terminal-specific reference signal on the basis of the detected scheduling information, wherein the first scheduling information includes an indicator indicating one or more of the settings, and the large scale properties of the terminal-specific reference signal are defined according to the setting indicated by the indicator during the detection of the first scheduling information, and a preset setting from among the one or more settings set during the detection of the second scheduling information.
