ABSTRACT:
A wireless communication system (20) includes using multiple antennas (30, 32) for simultaneous transmissions to multiple mobile stations (24, 26). A distributed multiple antenna scheduling (DMAS) technique includes selecting a plurality of mobile stations for at least receiving simultaneous transmissions on at least one selected subcarrier from within a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed example, a plurality of mobile stations are selected for each subcarrier within the carrier bandwidth. A disclosed example includes grouping subcarriers together into subsets to reduce computation complexity for determining which mobile stations to select for the simultaneous transmission.
