INTER-CELL INTERFERENCE COORDINATION IN A WIRELESS COMMUNICATION SYSTEM

Title:

INTER-CELL INTERFERENCE COORDINATION IN A WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2012/044019

Kind Code:

A3

Abstract:

Disclosed herein is a wireless communication system. More particularly, disclosed herein is a method and apparatus for coordinating and reducing inter-cell interference in a wireless communication system. A method of transmitting channel state information (CSI) measurement resource information by a base station includes determining first and second subframe sets, in which CSI measurement will be performed, among a plurality of downlink subframes, transmitting information indicating the first and second subframe sets to a terminal, and receiving the CSI of each of the first and second subframe sets from the terminal. A subframe belonging to the first subframe set and a subframe belonging to the second subframe set do not overlap, and some of the plurality of subframes do not belong to either of the first and second subframe sets.
