N2 - The next generation wireless local area network (WLAN) needs to significantly promote the area throughput in high dense scenario. OFDMA, considered as the key technology of next generation WLAN, has been adopted by IEEE 802.11ax. However, the existing studies on the OFDMA protocol have the interference extensions problem, i.e. multiple users are located in the dispersive area, and then the geographical interference area is expanded. In this paper, a spatial clustering group based OFDMA multiple access scheme (SCG-OFDMA) is proposed. SCG-OFDMA enables the users in close area to form spatial clustering groups dynamically, then the users in the spatial clustering group access channel and transmit data by OFDMA. It reduces the geographical interference area, and enhances the area throughput. Simulation results show that the area throughput of SCG-OFDMA is higher than OMAX and DCF by 20 % and 36 % respectively.
