最重要的无线网络之一的无线局域网（WLAN）的IEEE 802.11ax将于2020年发布。近年来，超高清视频服务和实时应用越来越受到关注。因此，下一代WLAN（超越IEEE 802.11ax）：IEEE 802.11be任务组（TGbe）于2019年正式成立，以实现极高吞吐量（EHT）为核心技术目标。本文对IEEE 802.11be的关键技术进行了调查和分析，并进一步提出了我们的观点和见解。具体来说，本文对IEEE 802.11be进行了简要概述，包括目标场景和技术目标、关键技术概述以及标准化进程。之后，我们对IEEE 802.11be的多频段运行、多AP协调、增强链路可靠性、延迟和抖动保证等关键技术进行了进一步的研究、分析和展望。据我们所知，这是第一个对 IEEE 802.11be 进行调查、分析和提供见解的工作。
The IEEE 802.11ax for Wireless Local Area Network (WLAN), one of the most important wireless networks, will be released in 2020. In recent years, ultra-high definition video service and real-time applications attract increasing attention. Therefore, the next generation WLAN (beyond IEEE 802.11ax): IEEE 802.11be task group (TGbe) was formally established in 2019, which regards achieving extremely high throughput (EHT) as its core technical objective. This article investigates and analyzes the key technologies of IEEE 802.11be, and further provides our perspectives and insights on it. Specifically, this article gives a brief overview on IEEE 802.11be, including the target scenario and technical objective, key technologies overview, and the standardization process. After that, we further investigate, analyze and provide perspectives on the key technologies of IEEE 802.11be including multi-band operation, multi-AP coordination, enhanced link reliability, and latency & jitter guarantee. To the best of our knowledge, this is the first work to investigate, analyze and provide insights on IEEE 802.11be.
