METHOD FOR TRANSCEIVING CHANNEL STATE INFORMATION AND TRANSCEIVING DEVICE

WIPO Patent Application WO/2012/124892

A1

The present invention relates to a method, in which a terminal transmits channel state information in a multi-node system, which includes the steps of: receiving information about cooperative transmission candidate nodes and interference candidate nodes from a network; calculating first channel state information about the cooperative transmission candidate nodes; calculating second channel state information by assuming that the nodes included in the interference candidate nodes are interference nodes among the cooperative transmission candidate nodes; and transmitting the calculated first and second channel state information to the network.
