5G deterministic network key technology research and application

5G deterministic network is an important part to support the construction of 5G+ Industrial Internet, and it is of great significance to study the key technologies and landing schemes of 5G deterministic network. Firstly, 5G ultra-reliability low latency communication technology and frame replication and cancellation technology were studied to reduce transmission latency and improve reliability. Secondly, cyclic queue forwarding technology was explored in 5G networks to eliminate end-to-end jitter. Finally, a 5G deterministic network landing scheme was proposed and tested in actual industrial production labs. The test results show that the comprehensive performance of the proposed network scheme is better than the existing network schemes, and can meet the demand for 5G deterministic networks in many industrial scenarios.
