Title:
METHOD AND APPARATUS FOR MEASURING INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/066019
Kind Code:
A1
Abstract:
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 node set-specific interference measurement region (NSIR) setting message from a node set that comprises a portion of the nodes from the plurality of nodes; and measuring the interference in a resource region that is indicated by the NSIR setting message, wherein the NSIR setting message is characterized by all of the nodes in the node set comprising information for setting an interference measurement region for transmitting a zero-power channel state information (CSI) reference signal (RS).
