The present invention relates to a method for reducing interference in the downlink direction of a cellular radio communication system comprising base stations communicating with terminals using a frame structure showing a time and frequency extension, the frame comprising a preamble portion and at least one data portion, the terminals being adapted to receive frames for which the receive power of the at least one data portion is varying in a predefined range relative to the receive preamble power of the preamble portion, According to the present invention, the method comprises the steps of: transmitting the part of the data portion destined to the terminal with a transmit power adopted to generate a first receive power (Plow) at the terminal within the range if said terminal belongs to a first group of terminals; transmitting the part of the data portion destined to the terminal with a transmit power adapted to generate a second receive power (Phigh) at the terminal within the range, the second receive power being higher than the first receive power, If the terminal belongs to a second group of terminals.
