摘要： A method and system is disclosed for grouping the multiple stations connected to an access point (AP). The system and method comprise sending a sounding packet to a plurality of stations, wherein the stations may be all or part of the stations that are located within the range of the AP. The stations that receive the sounding packets respond to the AP, and the AP determines the channel state information (CSI) from the responses. According to the CSI, the AP divides the multiple stations into several groups. According to an embodiment of the present invention, a confirmation step is performed to each group of stations, respectively. The AP sends a second sounding packet to each group of stations, and verifies the CSI between each station group by group. Therefore, the method and system provides for monitoring the validation of each group by periodically sending sounding packets to each group.

摘要： The present invention provides a method for dynamic channel assignment for a wireless communication system. First, a respective channel allocation probability vector at each mobile terminal is randomly generated, and is then sent to the base stations covering the mobile terminal. Subsequently, the channel allocation probability vectors are integrated into channel allocation information for the mobile terminals covered by the base station. Afterwards, based on the channel allocation information, a corresponding channel allocation notice is sent to the mobile terminals covered by the base station, respectively. Finally, according to the channel allocation notice, the channels of the base station are assigned for the mobile terminals covered by the base station.
