Abstract(in English)	This paper proposes a new wireless resource allocation method for MIMO-SDMA/TDMA systems. It's difficult to assign the wireless resources efficiently because there're many combinations of stations which communicate simultaneously in MIMO-SDMA. We propose a new method by which we can calculate the time resource assignment efficiently among some combinations of stations considering the channel capacities required by the stations. We evaluate the possibility of unsatisfied resource assignment when the AP is equipped with 4 antennas and each station is equipped with 2 antennas using MIMO-SDMA in 100MHz bandwidth. From the simulation, using the proposed method, probability of the unsatisfied resource assignment can be reduced to once or twice a day.
