摘要:

随着人们对无线业务和服务质量(QoS)要求的不断提高,无线局域网(WLAN)已经发展成为影响人类生活的最主要的无线网络之一。作为应用最广泛的无线局域网标准,电气和电子工程师协会(IEEE)802.11将发布即将到来的下一代无线局域网标准修正案:IEEE 802.11ax。本文对IEEE 802.11ax的应用场景、技术需求、标准化进程、关键技术、性能评估等进行了全面的综述和分析。本文从IEEE 802.11ax的技术目标和要求出发,特别关注高密度部署场景。然后,详细讨论了IEEE 802.11ax的关键技术,包括物理层(PHY)增强、多用户(MU)介质访问控制(MU-MAC)、空间复用(SR)和功率效率,涵盖了标准化技术以及最新的学术研究。此外,IEEE 802.11ax的性能要求进行评估,通过一个新提出的系统和链路级集成仿真平台(SLISP)。仿真结果证实,IEEE 802.11ax在高密度部署中显著改善了用户体验,同时成功实现了项目授权请求(PAR)中的平均每用户吞吐量要求,是传统IEEE 802.11的四倍。最后,潜在的进展超出IEEE 802.11ax进行了讨论,以完成对最新的IEEE 802.11ax的整体研究。据我们所知,本文是第一个直接调查和分析IEEE 802.11ax最新稳定版本的研究,也是第一个全面深入评估IEEE 802.11ax性能要求合规性的工作。

英文摘要:

With the ever-increasing demand for wireless traffic and quality of serives (QoS), wireless local area networks (WLANs) have developed into one of the most dominant wireless networks that fully influence human life. As the most widely used WLANs standard, Institute of Electrical and Electronics Engineers (IEEE) 802.11 will release the upcoming next generation WLANs standard amendment: IEEE 802.11ax. This article comprehensively surveys and analyzes the application scenarios, technical requirements, standardization process, key technologies, and performance evaluations of IEEE 802.11ax. Starting from the technical objectives and requirements of IEEE 802.11ax, this article pays special attention to high-dense deployment scenarios. After that, the key technologies of IEEE 802.11ax, including the physical layer (PHY) enhancements, multi-user (MU) medium access control (MU-MAC), spatial reuse (SR), and power efficiency are discussed in detail, covering both standardization technologies as well as the latest academic studies. Furthermore, performance requirements of IEEE 802.11ax are evaluated via a newly proposed systems and link-level integrated simulation platform (SLISP). Simulations results confirm that IEEE 802.11ax significantly improves the user experience in high-density deployment, while successfully achieves the average per user throughput requirement in project authorization request (PAR) by four times compared to the legacy IEEE 802.11. Finally, potential advancement beyond IEEE 802.11ax are discussed to complete this holistic study on the latest IEEE 802.11ax. To the best of our knowledge, this article is the first study to directly investigate and analyze the latest stable version of IEEE 802.11ax, and the first work to thoroughly and deeply evaluate the compliance of the performance requirements of IEEE 802.11ax.
