摘要
URLLC是5G三大应用场景之一,但5G现网全面支持URLLC业务仍存在一些问题。首先分析了URLLC R15版本支持低时延和高可靠的标准化关键技术,然后分析了R16版本支持TSN确定性需求技术方案和超高可靠性增强方案,为5G商用URLLC明确了需要引入的增强功能和面临的挑战。
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.
