A Just-in-Time Medium-Transparent MAC Protocol for Multi-Service 5G X-haul Transport Networks

Description

We introduce a Just-In-Time Medium- Transparent MAC (jMT-MAC) protocol that provides a transmission schedule for Analog-RoF Fiber-Wireless 5G and beyond X-haul networks supporting multiple services with variable packet sizes. jMT-MAC efficiently places each pending data packet in the polling-sequence, according to an elegant multi-objective optimization model, targeting the employment of the whole available delay budget of the higher priority flows while also considering the delay minimization of all packets, including Best Effort flows. Simulation results show the optimization model of jMT-MAC achieving the 5G fronthaul and URLLC KPIs while reducing delays for low-priority traffic by up to 100% compared to State-of-the-Art protocols.
