METHOD FOR REDUCING INTERFERENCE IN A CELLULAR RADIO COMMUNICATION NETWORK, CORRESPONDING INTERFERENCE COORDINATOR AND BASE STATION

The present invention relates to a method for reducing interference in a cellular radio communication network, said network comprising a plurality of base stations and a plurality of terminals to be scheduled on frequency and/or time resources. According to the present invention, the method comprises the steps of: determining interference parameters from at least two base stations; reporting said interference parameters from said at least two base stations to an interference coordinator; determining at said interference coordinator resources to be allocated to said plurality of terminals minimising an overall interference criterion; reporting from said interference coordinator to said at least two base stations the resource allocated to the different terminals.
