New use cases and vertical integration in the area of industrial automation are making flexible and large-scale communication systems with real-time capabilities more essential than ever before. Time-sensitive networking (TSN) is addressing a unification of many existing industrial Ethernet technologies to leverage cross-domain flexibility while guaranteeing end-to-end service requirements. Extending TSN capabilities over the wireless domain using 5G cellular network technologies is currently seen as a promising approach to meet the requirements of a highly flexible cyber-physical system as envisioned in the context of Industry 4.0. In this paper, we provide a detailed overview on the integration of 5G and TSN. We present a system-level simulator to investigate the impact and derive requirements on the end-to-end system when supporting time-sensitive deterministic traffic. Based on the results, we analyze implications on the scheduling of multiple end-to-end streams with cross traffic over an integrated 5G and TSN network.
