Prioritized-Resource-Sharing Scheduling in 5G-TSN Integrated Networks

The 5G and Time-Sensitive Networking (TSN) integrated networks are promising communication solutions for future smart factories. The mixed time-triggered and event-triggered traffic inside the smart factories presents great challenges to the scheduling in 5G-TSN integrated networks. This paper proposes a prioritized-resource-sharing scheduling (PRSS) mechanism based on semi-persistent scheduling to guarantee the deterministic transmissions of event-triggered time-sensitive flows (ET-TS) while improving the resource utilizations. The proposed PRSS employs the max-min fair share algorithm in the dynamic scheduling for non-time-sensitive traffic to ensure the fairness of the resource allocation. Simulation results show that the proposed PRSS mechanism achieves lower delay and better resource utilizations compared with conventional scheduling mechanisms, especially for the ET-TS flows.
