Abstract: Based on 5G communication in the distribution network, how to build a technical solution that meets the delay and reliability of 5G communication in the distribution network has become a focus of research and thinking for current technicians. The full text uses literature research methods and other methods to first design a deterministic architecture for 5G communication delay in the distribution network from two aspects: the overall framework of the engine, engine process, and protocol design. Then, direct and indirect solutions for calculating the 5G communication architecture in the distribution network are provided, and delay management strategies and algorithm evaluations are proposed.
