Method and apparatus for detecting the locations of terminals in a multi-node system

Provided are a method and an apparatus for detecting the locations of terminals in a multi-node system. A plurality of nodes transmit location reference signals which are distinguished by node, and a terminal performs feedback of channel information on each node using the location reference signals. Various signaling for detecting the locations of the terminals may be performed for each node, that is, for each point, rather than cell-based signaling.
