Method for minimising interference in a cellular ofdm communications system and base station and mobile station for this

Method for minimising interference in a cellular OFDM communication network, wherein

• mobile stations allocated to a cell measure the radio channel quality and the interference level as a function of the individual sub-carriers and transmit these to the 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.
