摘要： A scheduling method in a distributed antenna system is provided. Each of a plurality of Mobile Stations (MSs), respectively corresponding to each subchannel, are classified as a Single Transmission (ST) MS or a Cooperative Transmission (CT) MS according to a CT criterion. An MS with a maximum channel capacity is selected from among the classified MSs. Resources arc allocated to a corresponding subchannel when the selected MS is the ST MS, and resources arc allocated using a CT scheduling technique when the selected MS is the CT MS. The classifying, selecting and allocating steps are repeated until allocation of resources is completed.
