  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.
