Method for reducing interference in the downlink direction of a cellular radio communication network and corresponding base station

A method for reducing interference in the downlink direction of a cellular radio communication system, said method comprising:

• one or more base stations communicating with terminals using a frame structure showing a time and frequency extension, said frame comprising a preamble portion and at least one data portion, said one or more base stations being adapted to transmit frames to said terminals for which the receive power of said at least one data portion is varying in a predefined range relative to the preamble receive power of said preamble portion;
• transmitting the part of said data portion destined to said terminal with a transmit power adapted to generate a first receive power at said terminal within said range if said terminal belongs to a first group of terminals;
• transmitting the part of said data portion destined to said terminal with a transmit power adapted to generate a second receive power at said terminal within said range, said second receive power being higher than said first receive power, if said terminal belongs to a second group of terminals, wherein said terminals belonging to said first group are scheduled in said frame following a first frequency reuse scheme and said terminals belonging to said second group are scheduled in said frame following a second frequency reuse which is less efficient than said first frequency reuse scheme, and wherein said terminals scheduled according to said first frequency reuse scheme and terminals scheduled according to said second frequency reuse scheme share a common time domain in said frame and said second frequency reuse scheme uses 1/n of available frequencies by dividing the cell into n sectors.
