| Abstract: | 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. |
