Abstract： The ITU(International Telecommunication Union) defines three major 5G application scenarios: eMBB, mMTC and URLLC. With the maturity and commercialization of 5G, URLLC as an important entry point in the vertical industry is also gradually improving and optimizing. This paper firstly introduces the evolution of URLLC standard, and then analyzes the key technologies to achieve URLLC from three aspects of low latency, high reliability and multiplexing of URLLC and eMBB. Finally, the integration of URLLC and TSN is described.
