May 2023 doc.: IEEE 802.15-23-0242-00-006a Introduction Coexistence of multiple BANs and other UWB applications (e.g. IEEE 802.15.4ab) is a key issue in providing high dependability In multiple BAN coexistence, we propose a managed synchronous superframe structure to avoid packet collisions even between different BANs, which is optimally controlled under multiple BAN coexistence situations We carry out fundamental MAC performance evaluation to demonstrate the importance of the proposed structure based on an interference model Submission Slide 3 D.
