Chance-Constrained Headroom Sizing for Teleoperation-Critical Handovers in 5G/6G Networks
Year: 2026
Type: article
Abstract: Teleoperated driving relies on a real‑time uplink video stream whose latency, jitter, and loss must remain tightly bounded, making intra‑frequency handovers a critical challenge when the target cell is congested. This paper develops a stochastic framework for proactive handover preparation that quantifies the minimum preconditioning headroom required to maintain probabilistic QoS guarantees for the teleoperation video stream. The model combines bursty MMPP uplink traffic with stochastic background load and computes the minimum feasible headroom as a function of target‑cell utilization, preconditioning lead time, and interruption gap. The analysis reveals sharp feasibility boundaries: headroom requirements grow rapidly with cell load, and excessive interruption gaps render strict QoS unattainable. The framework is designed to operate within a Network Digital Twin, which continuously ingests telemetry and predicted vehicle trajectories to evaluate upcoming handovers and pre‑compute the minimum capacity reservation needed at candidate target cells.
