摘要

Wi-Fi 6是Wi-Fi联盟对IEEE 802.11ax的新命名方式，以便于这项Wi-Fi新技术的推广。Wi-Fi 6技术聚焦高密度场景的多用户性能、效率等方面，引入OFDMA、上行MU-MIMO等多用户技术，极大提升系统容量，降低传输时延。阐述OFDMA、MU-MIMO、MU-RTS/CTS技术的原理，详细介绍多用户场景的通信流程，并从理论角度分析Wi-Fi 6的上下行并发用户能力，最后对Wi-Fi 6技术的应用前景进行展望和总结。

Abstract

Wi-Fi 6 was the new name of IEEE 802.11ax by the Wi-Fi Alliance to facilitate the promotion of new Wi-Fi technology.Wi-Fi 6 technology focused on improving multi-user performance and efficiency in dense deployment scenario.Introducing OFDMA

UL MU-MIMO and other multi-user collaboration technologies

greatly increases system capacity and reduces transmission delay.The principles of OFDMA

MU-MIMO

MU-RTS/CTS technologies were described

the communication process in multi-user scenario was introduced in detail

and the UL and DL simultaneous user numbers of Wi-Fi 6 were analyzed in theory.Finally

the application potential of Wi-Fi 6 were discussed.
