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 includes transmitting a reference signal including a first slot and a second slot in a downlink subframe having a general cyclic permutation (CP) Mapping a part of the common reference signals for the antenna ports below, mapping the channel state information reference signals for the antenna ports of 8 or less in the downlink subframe according to a predetermined pattern, And transmitting the downlink sub-frame to which the channel state information reference signal is mapped, wherein the predetermined pattern is a pattern in which the channel state information reference signal for the antenna port of 8 or less is transmitted in the downlink sub- Wherein the OFDM symbol is mapped onto two OFDM symbols spaced apart by one OFDM symbol on the data area, Some of the reference signals may be limited to a common reference signal for an antenna port of 2 or less.
