METHOD AND APPARATUS FOR MEASURING INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2013/066018

A1

Provided is a method for measuring interference by a user equipment (UE) in a multi-node system comprising inside a cell a base station and a plurality of nodes that are controlled by the base station, and the user equipment for same. The method comprises: receiving from the base station a cell-specific interference measurement setting message; and measuring the interference in a resource region indicated by the cell-specific interference measurement setting message, wherein the cell-specific interference measurement setting message is characterized by all of the nodes in the cell comprising information for setting a cell-specific interference measurement region for transmitting a zero-power channel state information (CSI) reference signal (RS).
