Coordinated TDMA MAC Scheme Design and Performance Evaluation for the Next Generation WLAN: IEEE 802.11be

The next generation Wireless Local Area Network (WLAN) standard: IEEE 802.11be focuses on achieving extremely high throughput (EHT). High-dense deployment network is still one challenging and important scenario for IEEE 802.11be. In order to improve quality of experience (QoE) of users in high-dense scenario, access point (AP) coordination is considered as a promising technology for IEEE 802.11be. Many researchers and engineers have proposed different specific AP coordination solutions, but the work on the performance verification of the proposed protocol is not yet fully validated. This article focuses on the detailed protocol design and performance of the Coordinated time division multiple access (co-TDMA), one type of AP coordination technologies. We design a specific simulation protocol implementation scheme, perform simulations based on the system-level and link-level integrated simulation platform, evaluate the performance of co-TDMA. Simulation results show that the co-TDMA protocol can improve the throughput and packet loss rate performance under certain network scenarios.
