| Abstract: | URLLC is one of the three major 5 G scenarios,but there are still some problems in fully supporting URLLC services in current 5 G networks.This paper first analyzes the key standard technologies of URLLC in 3 GPP R15 release to support lower latency and higher reliability,and then analyze the technical solutions and the ultra-high reliability enhancement solutions in R16 release to support the deterministic transmission requirements of TSN.The work of this paper clarifies the necessary enhanced functions and challenges for URLLC applications in the commercial 5 G. |
