URLLC in B5G Networks: Use Cases, TSN/DetNet Extension, and Pending Issues.

Originally, 5th Generation (5G) mobile networks were expected to carry the demands of the Internet of Everything (IoE) and Ultra-Reliable and Low-Latency Communications (URLLC) services. However, state-of-the-art of wireless mobile technologies failed to meet these expectations. Beyond 5G (BG5) wireless networks have the potential to leverage the benefits of a mature transported network, and enhanced capabilities related to high reliability and extremely low End-to-End Latency. This paper investigates the potential of B5G with extreme URLLC use cases. It also provides an overview and vision of the potential integration of B5G with Time-Sensitive Networking (TSN) for indoor scenarios, and Deterministic Networking (DetNet) with Segment Routing (SR) for outdoor scenarios.
