Recent advancements in wireless local area network (WLAN) technology include IEEE 802.11be and 802.11ay, often known as Wi-Fi 7 and WiGig, respectively. The goal of these developments is to provide Extremely High Throughput (EHT) and low latency to meet the demands of future applications like as 8K videos, augmented and virtual reality, the Internet of Things, telesurgery, and other developing technologies. IEEE 802.11be includes new features such as 320 MHz bandwidth, multi-link operation, Multi-user Multi-Input Multi-Output, orthogonal frequency-division multiple access, and Multiple-Access Point (multi-AP) coordination (MAP-Co) to achieve EHT. With the increase in the number of overlapping APs and inter-AP interference, researchers have focused on studying MAP-Co approaches for coordinated transmission in IEEE 802.11be, making MAP-Co a key feature of future WLANs. Moreover, similar issues may arise in EHF bands WLAN, particularly for standards beyond IEEE 802.11ay. This has prompted researchers to investigate the implementation of MAP-Co over future 802.11ay WLANs. Thus, in this article, we provide a comprehensive review of the state-of-the-art MAP-Co features and their shortcomings concerning emerging WLAN. Finally, we discuss several novel future directions and open challenges for MAP-Co.

新兴 WLAN 上的多 AP 协调方法调查：未来方向和开放挑战


无线局域网 (WLAN) 技术的最新进展包括 IEEE 802.11be 和 802.11ay，通常分别称为 Wi-Fi 7 和 WiGig。这些开发的目标是提供极高吞吐量 (EHT) 和低延迟，以满足 8K 视频、增强现实和虚拟现实、物联网、远程手术和其他开发技术等未来应用的需求。 IEEE 802.11be 包括 320 MHz 带宽、多链路操作、多用户多输入多输出、正交频分多址和多接入点 (multi-AP) 协调 (MAP-Co) 等新功能达到EHT。随着重叠AP数量和AP间干扰的增加，研究人员重点研究IEEE 802.11be中协调传输的MAP-Co方法，使MAP-Co成为未来WLAN的关键特征。此外，EHF 频段 WLAN 中也可能出现类似的问题，特别是对于 IEEE 802.11ay 以外的标准。这促使研究人员调查 MAP-Co 在未来 802.11ay WLAN 上的实施情况。因此，在本文中，我们对新兴 WLAN 的最新 MAP-Co 功能及其缺点进行了全面回顾。最后，我们讨论了 MAP-Co 的几个新的未来方向和面临的挑战。
