论文摘要
随着4K/8K视频的出现,视频传递的吞吐量需求将使数十Gbps的增长。其他新的高通量和低延迟视频应用程序,包括增强现实(AR),虚拟现实(VR)和在线游戏,也正在激增。由于相关的严格要求,在无线局域网(WLAN)上支持这些应用程序远远超出了新的WLAN标准的功能-IEEE 802.11AX。为了满足这些新出现的需求,IEEE 802.11将发布新的修订标准IEEE 802.11BE-极高的吞吐量(EHT),也称为无线预后(WI-FI)7。本文提供了有关关键媒体访问控制(MAC)层(MAC)层(PHY)的关键媒体访问控制(MAC)的全面调查,包括在e H中进行了多种调查,包括EHT INCELITIS和MURTIE INTICE组,包括EHT Incortion(包括EHT),包括EHT的分组(包括eht Iniveriation and Iniver Iniver Inive and Iniver Iniver(包括)(包括eHT)。 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)).该调查涵盖了EHT标准中讨论的关键技术以及全球研究的最新进展。此外,讨论了EHT以外的潜在发展,以为WLAN提供一些可能的未来研究指示。
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.
