Abstract:
The present invention relates to a method for transmitting data from a base station to a terminal in a wireless communication system, wherein the method includes the steps of: determining a terminal for transmitting downlink data; when the downlink data is transmitted, confirming the kind of subframe in which the downlink data is transmitted; when the subframe is a normal subframe, transmitting the downlink data on the basis of a cell specific reference signal (CRS) or a demodulation reference signal (DMRS); and, when the subframe is a multimedia broadcast multicast service signal frequency network (MBSFN) subframe, transmitting the downlink data on the basis of the DMRS.
