Abstract (in Japanese) (See Japanese page) 
(in English) In the next-generation Wi-Fi standard IEEE 802.11be, the "Multi-Link Operation (MLO)" feature has been introduced, which enables devices to be equipped with multiple wireless interfaces and simultaneously utilize multiple frequency bands. This allows for high-speed and low-latency communication. In the real use case of wireless LAN, it is expected that devices compatible with the latest standard and legacy Single-Link Operation (SLO) devices will exist. We have demonstrated that not only MLO devices may not achieve their potential but legacy devices may also lose transmission opportunities. This was achieved by constructing an analytical model considering MLO channel access in coexistence environments. In such environment, optimisation of access control parameters is required to maintain both MLO and legacy devices have sufficient transmission opportunities. This paper proposes the throughput optimization in the coexistence of legacy devices in IEEE 802.11be networks. We derive the CW value from the analytical model such that the transmission probability of the MLO device and the legacy device becomes equal. The validity of the proposed analytical method is demonstrated through comparison with simulation results.
