    • In a wireless communication system for communicating with a plurality of stations at the same point of time with the same frequency using a Space Division Multiple Access (SDMA), wireless resources are allocated by a first decision unit which evaluates performance of each station obtained when the SDMA is used and which determines periods of time to be allocated to groups of stations formed according to the SDMA technique. Using a first evaluation unit and a second evaluation unit to evaluate performance required by each station and each application, the first decision unit allocates the wireless resources to the stations. It is therefore possible that the wireless resources are efficiently allocated to the stations while preventing an event in which the wireless resources are excessive or insufficient for required quality of service.
    • 在用于使用空分多址(SDMA)以相同频率在同一时间点与多个站进行通信的无线通信系统中,无线资源由第一决策单元分配,该第一决策单元评估当 使用SDMA,并确定要分配给根据SDMA技术形成的站组的时间段。 使用第一评估单元和第二评估单元来评估每个站点和每个应用所需的性能,第一决策单元向站点分配无线资源。 因此,可以将无线资源有效地分配给站,同时防止无线资源过多或不足以满足所需服务质量的事件。
