Abstract: PROBLEM TO BE SOLVED: To provide a radio communication system (20) which includes using a plurality of antennas (30, 32) in order to perform simultaneous transmission to a plurality of mobile stations (24, 26). SOLUTION: A distributed multiple antenna scheduling (DMAS) technique includes selecting the plurality of mobile stations which receive at least simultaneous transmission on at least one selected subcarrier from the inside of a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed embodiment, the plurality of mobile stations are selected for each subcarrier in the carrier bandwidth. The embodiment includes grouping the subcarriers into a subset together in order to reduce complicatedness of calculation for determining which mobile station should be selected for the simultaneous transmission.
