The delay guarantee of ultra-reliable and low-latency communication ( URLLC) traffic underresource reservation policy was analyzed when both URLLC traffic and enhanced mobile broadband ( eMBB) traffic co-exist in the fifth generation of mobile communications system ( 5G) system.

The results showed that,when the system resource was fixed,the delay distribution of eMBB traffic would be influenced by the amount of resource reserved for URLLC traffic,and the deteriorate level greatly depended on the reservation ratio.
