Traffic Scheduling for 5G-TSN Integrated Systems

The fourth industrial revolution will significantly improve the level of informatization and intelligence of the industry by building a smart factory. As an essential part of the smart factory, industrial communication systems face rigorous challenges. On the one hand, many smart factory applications demand data delivery with ultra-high reliability within a very low end-to-end latency. On the other hand, new services place high demands on the flexibility and scalability of the communication system. Industry-standard organizations have embarked on research and proposed several potential solutions. The time-sensitive networking (TSN) task group has developed a series of ethernet-based standards to address issues such as time synchronization and traffic scheduling in industrial networks. Additionally, ultra-reliable and low-latency communications (URLLC) are supported by the 5th generation (5G) mobile communications technology. The combination of 5G and TSN technologies as a solution for industrial communication networks has received much attention, and many related studies have been conducted. In this paper, we investigate how to achieve low-latency communication in a 5G-TSN integrated network by considering non-real-time communication services with high throughput requirements. Simulation results demonstrate that the proposed approach performs well in terms of reducing end-to-end latency and improving system throughput.
