Patent ID: 8310995

Claim:
A wireless communication apparatus for communicating with a plurality of stations using Space Division Multiple Access (SDMA), comprising: a channel state information collecting unit which collects channel state information from each channel between the wireless communication apparatus and each station of the plurality of stations; a wireless resource allocating unit which generates a plurality of SDMA station combinations as SDMA group candidates from which a plurality of SDMA groups for conducting SDMA for the plurality of stations are selected such that at least one station of the plurality of stations may belong to multiple SDMA groups of the plurality of SDMA groups for conducting SDMA, estimates a communication performance for each of the stations belonging to the SDMA group candidates by using the channel state information, performs an optimization of an evaluation value of an objective function used to evaluate a degree of achieving an object of a system under conditions of constraint that include the communication performance estimated for each station and a communication performance required for each station or a communication performance required for an application provided to the stations, and determines, in accordance with a result of the optimization, periods of time to be respectively allocated to the plurality of SDMA groups selected from the SDMA group candidates to thereby allocate wireless resources to the plurality of stations; and a signal processing unit which communicates with the plurality of stations according to the wireless resources thus allocated.
