Abstract
The present invention discloses a method and an apparatus for transmitting a reference signal in a wireless communication system. More specifically, the method comprises configuring a first antenna group on the basis of a plurality of antenna elements configured by a horizontal domain antenna element and a vertical domain antenna element; transmitting a configuration with regard to a specific sub frame to first terminals through a first antenna group; receiving a sounding reference signal (SRS) through the specific sub frame from the first terminals; selecting at least one second terminal among the first terminals on the basis of the sounding reference signal; and transmitting a channel state information-reference signal (CSI-RS) with respect to the at least one second terminal, wherein the specific sub frame is characterized in that at least a part of a source area is configured by a multicast broadcast single frequency network (MBSFN) sub frame.
