Patent ID: 7764663

Claim:
A method for minimizing interference in a cellular OFDM communication network, wherein mobile stations allocated to a cell measure radio channel quality and interference level as a function of individual sub-carriers and transmit these to a base station of the cell, the radio channel quality is combined into a radio quality parameter for each mobile station, the mobile stations are divided into groups according to the radio quality parameter, the interference level of mobile stations which belong to a first group of mobile stations, with a radio quality parameter that is lower than that of at least one other group, are combined into a common interference level, the sub-carriers of the OFDM communication network are divided into quantities according to the common interference level of the first group of mobile stations, and sub-carriers which belong to a first quantity, with a common interference level which is lower than that of at least one other quantity, are selected as preferred sub-carriers for transmission to the mobile stations which belong to the first group.
