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, said frame comprising a preamble
portion and at least one data portion, said terminals being adapted to
receive frames for which the receive power of said at least one data
portion is varying in a predefined range relative to the receive preamble
power of said preamble portion,
According to the present invention, the method comprises the steps of:
transmitting the part of said data portion destined to said terminal with
a transmit power adapted to generate a first receive power (Plow) 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(Phigh) 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.
