The article focuses on the 3GPP key features URLLC and tells more about how to realize the uRLLC function to support more industrial scenarios. As the industrial application will require more specific and more detailed function set. The article creatively constructed the modular to design URLLC system from multi-dimensions. The system with modular blocks is a common methodology for planning the layout of future URLLC system commercial comprising which is helpful for the design and test

... . It is obvious that 5G network is developing rapidly from the basic high data throughput as the startup to high reliability and low latency. We are placing great hopes on it for future low-latency scenarios. The modular design methodology for improving the system realization and optimization will develop soon. The vision and method will help us open up more mindset to build promising 5G system for verticals.
