Compensating the Packet Delay Variation for 6G Integrated with IEEE Time-Sensitive Networking

2026-02-24

AI Summary

This work addresses the packet delay jitter induced by the stochastic nature of wireless channels in the integration of 6G and IEEE Time-Sensitive Networking (TSN). To tackle this challenge, the paper proposes a virtual time-slot-based time-aware scheduling architecture that, for the first time, incorporates a dejittering mechanism into 6G-TSN convergence scenarios. By jointly optimizing virtual time-slot modeling and dejittering techniques, the proposed approach effectively compensates for delay variations in wireless environments, enhancing scheduling stability for time-critical traffic while maintaining high reliability. Experimental results demonstrate that the scheme significantly reduces packet delay jitter and reveals the impact of time-slot granularity on the number of schedulable TSN flows, thereby offering both theoretical insights and practical guidance for the co-design of 6G and TSN systems.

Abstract

6G is deemed as a key technology to support emerging applications with stringent requirements for highly dependable and timecritical communication. In this paper, we investigate 6G networks integrated with TSN and how to compensate for wireless stochastic behavior which involves a large intrinsic packet delay variation. We evaluate a 6G solution to reduce packet delay variation that is based on de-jittering. For this, we propose to use virtual timeslots for providing the required time-awareness. We discuss the benefits of the proposed solution while evaluating the impact of the timeslot size on the number of schedulable TSN streams.
