Abstract
For 5G, the coexistence of two scenarios within the same network - ultrareliable low-latency communication (URLLC) and enhanced mobile broadband (eMBB) - is an actual task. For a scheme with the occupation of not the whole, but a part of the resource block, a model of coexistence of narrow-band URLLC traffic and broadband eMBB traffic in the form of a queuing system with priority access - reducing and interrupting the service of broadband traffic when narrow-band traffic arrives - is proposed. The authors formulate the problem of maximizing the average speed of broadband traffic transmission by the values of speed levels and with restrictions on the probability of blocking and the probability of interrupting broadband traffic service. The results of a numerical analysis of priority access efficiency indicators, such as the average number of eMBB sessions and probability of service interruption, are presented.
