Abstract
As one of the three major 5G scenarios, URLLC has features such as ultra-low latency and ultra-high reliability. It provides high reliability transmission guarantee of real-time information for industrial automation, smart grid and other application scenarios. In order to realize the low latency and high reliability features of URLLC, 3GPP has added physical layer and high level technology solutions in R15, R16 and R17 phases respectively. This paper firstly introduces the key technologies of low latency and high reliability. Secondly, based on the typical services and requirements of URLLC, four major URLLC scenarios are proposed to be graded. After an in-depth discussion of the requirements, this paper gives deployment options for different hierarchical scenarios and various enabling technologies for URLLC, thus providing some support for the integration of URLLC with industry applications.
