摘　　要：URLLC作为5G三大场景之一,其具有超低时延和超高可靠的特性,可广泛应用于多个行业中。在URLLC低时延高可靠的关键技术研究的基础上,对TDD/FDD NR下的eMBB与URLLC空口数据收发时序和环回时延进行了对比分析,提出了URLLC网络部署建议。As one of the three major 5 G scenarios,URLLC has the characteristics of ultra-low delay and ultra-high reliability and can be widely used in many industries.Based on the research of the key technologies for short-time delay and high reliability of URLLC,this paper makes comparative analyses on the transceiving timing and loopback delay of air interface data between eMBB and URLLC in TDD/FDD NR,and proposes deployment suggestions for URLLC networks.
