METHOD AND DEVICE FOR AVOIDING INTER-CELL INTERFERENCE IN A WIRELESS ACCESS SYSTEM

WIPO Patent Application WO/2012/108604

A1

According to the present invention, a method for a relay node (RN) to reallocate a resource in order to avoid inter-cell interference (ICI) in a wireless access system includes: overhearing a control channel including downlink or uplink resource allocation information transmitted by a plurality of base stations to terminals in the coverage area of each base station; sharing the RN by means of the plurality of base stations; confirming that there is a resource area in which conflicts are occurring by comparing resource areas allocated to terminals in the coverage area of the RN through the control channel; and, if it is determined, on the basis of the confirmation result, that there is a resource area in which conflicts are occurring, reallocating a resource to the resource area in which conflicts are occurring.
