Abstract  Abstract

A method and apparatus for transmitting a downlink reference signal in a wireless communication system supporting multiple antennas for a wireless communication system. A method for transmitting a reference signal for an antenna port of 8 or less according to an embodiment of the present invention is a method for transmitting a reference signal for an antenna port of 4 or less in a downlink subframe including a first slot and a second slot Mapping a portion of the data; Mapping a channel state information reference signal for up to 8 antenna ports to the downlink subframe according to a predetermined pattern; And transmitting the downlink sub-frame to which the common reference signal and the channel state information reference signal are mapped, wherein the predetermined pattern is a pattern in which the channel state information reference signal for the 8 or less antenna ports is the downlink sub- And the common reference signals for the 4 or fewer antenna ports may be limited to a common reference signal for 2 or less antenna ports.
