主　　题：wireless local area network high density deployment scenarios unsaturated services spatial clustering group 

摘      要：In order to enhance the area throughput of next generation wireless local area network(WLAN)in high density scenarios,orthogonal frequency division multiple access(OFDMA)has been adopted as one of the key technologies in the next generation WLAN communication ***,the performance of the existing media access control(MAC)degrades significantly under unsaturated ***,this paper proposes a multi-user parallel contention channel MAC(MU-MAC)based on unsaturated services,which can effectively reduce the channel access conflict and improve the OFDMA access efficiency of cluster member *** this basis,MU-MAC is enhanced for the spatial clustering group(SCG)formation protocol and support for the unsaturated service ***,the optimal access radius when the service is in a non-saturated state is analyzed to make the relevant theoretical analysis more generally,and the expressions for the throughput and area throughput of the proposed protocol are modeled and *** simulation results verify the correctness of the theoretical analysis and the efficiency of the protocol *** results show that MU-MAC outperforms IEEE 802.11ax and OMAX protocol in area throughput by 40.72%and 104.15%,respectively.
