Method for transmitting enhanced reference signal in multi-antenna wireless communication system and apparatus therefor |
| abstract |
The present invention relates to a method and apparatus for transmitting a reference signal by a base station in a wireless communication system supporting multiple antennas. More specifically, the present invention comprises the steps of: transmitting a reference signal configuration including specific reference signal IDs configured to identify a plurality of antenna groups; transmitting at least one reference signal associated with the plurality of antenna groups; and receiving channel state information measured according to the at least one reference signal, wherein each antenna group includes a plurality of antennas which are grouped on the basis of a specific domain of the multiple antennas, and the plurality of antenna groups are configured to perform beamforming in different directions. |
