摘　　要：802.11ax是新型Wi-Fi的无线通信协议,可以有效提高Wi-Fi接入区域的系统吞吐量,为用户提供高效通信服务。当前Wi-Fi接入倾向于高密度部署,以提高网络吞吐量,但Wi-Fi网络是随机访问的,802.11ax协议架构增加了并行传输难度。首先介绍了基于802.11ax标准的密集用户网络场景架构,包括中央控制器主控接入点(Master Access Point,MAP)。其次分析用户随机接入过程中的终端设备干扰问题,进而提出基于802.11ax标准的无线网络干扰管理方案。根据从属接入点(Slave Access Point,SAP)上传到中央控制器MAP的相关信息进行分析计算,并将计算结果回传给SAP,保证SAP的有序访问和同步传输。最后经过仿真分析验证了该方案具有较低的干扰控制过程开销,能够有效提高系统吞吐量。802.11ax is a new Wi-Fi wireless communication protocol,which can effectively improve the system throughput in the Wi-Fi access area and provide users with efficient communication services.Current Wi-Fi access tends to be deployed in high density to improve network throughput,but Wi-Fi networks are accessed randomly,and the 802.11ax protocol architecture increases the difficulty of parallel transmission.Firstly,the dense user network scenario architecture based on the 802.11ax standard is introduced,including the central controller Master Access Point(MAP).Secondly,the terminal equipment interference problem in the random access process of users is analyzed,and a wireless network interference management scheme based on the 802.11ax standard is proposed.Analyze and calculate according to the relevant information uploaded by the Slave Access Point(SAP)to the central controller MAP,and send the calculation result back to the SAP to ensure the orderly access and synchronous transmission of the SAP.Finally,the simulation analysis verifies that the scheme has lower interference control process overhead and can effectively improve the system throughput.
