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 channel state information reference signal for an antenna port of 8 or less according to an embodiment of the present invention includes the steps of transmitting a channel state information reference signal for 8 or less antennas on a data area of a downlink subframe having a general cyclic prefix Mapping a channel state information reference signal for an antenna port according to a predetermined pattern and transmitting the downlink subframe to which a channel state information reference signal for the antenna port of 8 or less is mapped, Wherein the predetermined pattern is one in which a channel state information reference signal for the antenna port of 8 or less is mapped onto two OFDM symbols on the data area of the downlink subframe and one of four subcarrier positions in each of the two OFDM symbols And wherein the four subcarrier positions defined in the predetermined pattern are defined as being mapped to at least two consecutive subcarriers, Carrier position and another two consecutive subcarrier positions spaced apart by four subcarriers.
