Emerging real-time applications in industrial and consumer wireless networks impose stringent requirements on latency and reliability. To address these demands, IEEE 802.11bn introduces the Coordinated Restricted Target Wake Time (Co-RTWT) mechanism, which reserves channel access intervals for priority traffic. Co-RTWT is an extension of the previously existing R-TWT mechanism to multi-access point coordination (a new Wi-Fi 8 feature), enabling synchronized transmission scheduling across multiple access points. As a new mechanism, Co-RTWT has not yet been thoroughly investigated. In this paper, we present the current state of knowledge regarding R-TWT and Co-RTWT and highlight existing gaps in our understanding. Furthermore, we outline the research questions that will guide future studies and the methodology we intend to employ.
