5G uRLLC Service Delay Analysis and Wireless Network Deployment Scheme

The uRLLC scenario is one of the three major 5G application scenarios and will become an important scenario for 5G network evolution in the next few years. The uRLLC scenario supports ultra-low latency and highly reliable communication services. As the uRLLC scenario becomes more mature, operators need to analyze service latency from an end-to-end perspective. Firstly, this paper analyzes the composition of end-to-end delay of 5G network, and points out the direction of 5G network delay voltage drop based on the characteristics of high ratio and large jitter of air interface delay. Then, the wireless side technology schemes suitable for uRLLC scenario are introduced, and the effect of the schemes is analyzed. Next, the typical service delay and reliability requirements of uRLLC scenario are introduced, and the deployment suggestions of each technical solution of typical services are further put forward. Finally, through specific practical cases, the technical basis for expanding 5G convergence applications in vertical industries is provided.
