Abstract—With the emergence of 4k/8k video, the throughput requirement of video delivery will keep grow to tens of Gbps. Other new high-throughput and low-latency video applications including augmented reality (AR), virtual reality (VR), and online gaming, are also proliferating. Due to the related stringent requirements, supporting these applications over wireless local area network (WLAN) is far beyond the capabilities of the new WLAN standard – IEEE 802.11ax. To meet these emerging demands, the IEEE 802.11 will release a new amendment standard IEEE 802.11be – Extremely High Throughput (EHT), also known as Wireless-Fidelity (Wi-Fi) 7. This article provides the comprehensive survey on the key medium access control (MAC) layer techniques and physical layer (PHY) techniques being discussed in the EHT task group, including the channelization and tone plan, multiple resource units (multi-RU) support, 4096 quadrature amplitude modulation (4096-QAM), preamble designs, multiple link operations (e.g., multi-link aggregation and channel access), multiple input multiple output (MIMO) enhancement, multiple access point (multi-AP) coordination (e.g.,multi-AP joint transmission), enhanced link adaptation and retransmission protocols (e.g., hybrid automatic repeat request (HARQ)). This survey covers both the critical technologies being discussed in EHT standard and the related latest progresses from worldwide research. Besides, the potential developments beyond EHT are discussed to provide some possible future research directions for WLAN. Index Terms—IEEE 802.11be, EHT, Wi-Fi 7, Multi-link Operation,Multi-AP Coordination, MIMO Enhancement, HARQ.

Abstract—While the pace of commercial scale application of Wi-Fi 6 accelerates, the IEEE 802.11 Working Group is about to complete the development of a new amendment standard IEEE 802.11be – Extremely High Throughput (EHT), also known as Wi-Fi 7, which can be used to meet the demand for the throughput of 4K/8K videos up to tens of Gbps and low-latency video applications such as virtual reality (VR) and augmented reality (AR). Wi-Fi 7 not only scales Wi-Fi 6 with doubled bandwidth, but also supports real-time applications, which brings revolutionary changes to Wi-Fi. In this article, we start by introducing the main objectives and timeline of Wi-Fi 7 and then list the latest key techniques which promote the performance improvement of Wi-Fi 7. Finally, we validate the most critical objectives of Wi-Fi 7 – the potential up to 30 Gbps throughput and lower latency. System-level simulation results suggest that by combining the new techniques, Wi-Fi 7 achieves 30 Gbps throughput and lower latency than Wi-Fi 6. Index Terms—IEEE 802.11be, Wi-Fi 7, timeline, feature,throughput, latency.

Abstract—Last years we have witnessed the uprising of location-based applications, which depend on the device’scapabilities to accurately obtain their position. IEEE 802.11, foretelling the need for such applications, started the IEEE 802.11az work on Next Generation Positioning. Although this standard provides positioning enhancements for sub-6 GHz and mmWave bands, high accuracy in the order of centimeters can only be obtained in the latter band, thanks to the high temporal resolution from the multi-GHz bandwidth. This work presents the new techniques provided by IEEE 802.11az for enhanced secured positioning in the mmWave band. Additionally, this paper assesses 802.11az mmWave accuracy using a novel trigonometry solution, compares it with advanced positioning solutions, and identifies open research challenges. Index Terms—IEEE 802.11 standard, Next Generation Positioning, FTM, EDMG, mmWave

IEEE 802.11 DCF协议性能分析模型 钟萍, 施海彬, 庄玉祥, 石江宏, 陈辉煌 厦门大学信息科学与技术学院, 福建厦门361005 摘要： 提出了一种改进的二维Markov链模型用于分析IEEE 802.11 DCF协议. 该模型不仅考虑实际应用中饱和业务量和非饱和业务量的情况，而且考虑DCF协议的退避计时器的冻结状态和有限的重传次数. 通过对该Markov链模型稳定状态的求解并结合M/M/1/K排队模型，导出了DCF系统性能的理论模型. 仿真结果表明，该理论模型能够精确地预测广义IEEE 802.11 DCF协议的系统性能. 关键词: 无线局域网, IEEE 802.11, 分布式协调功能, Markov链模型 Abstract: This paper proposes an improved two-dimensional Markov chain model for the performance analysis of the IEEE 802.11 DCF protocol. The model is applicable to both saturated and unsaturated traffic conditions. Moreover, it extends the existing models to take into account previously-ignored MAC layer factors such as backoff freezing and limited times of retry. In addition, by deriving the stationary state of the Markov model and considering an M/M/1/K queuing model, we further derive a theoretical model for evaluating performance of the general IEEE 802.11 DCF protocols. Accuracy of the proposed theoretical model is validated with simulation results. Key words: wireless local area network, IEEE 802.11, distributed coordination function, Markov chain model
