One of the challenging tasks in 5G networks is to organize a joint URLLC (ultra-reliable and low-latency communication) and eMBB (enhanced mobile broadband) transmission in such a way that provides the priority to URLLC connections. The eMBB users suffer quality of service degradation, primarily bit rate degradation. In the paper, we provide a queuing model for analyzing this effect depending on several path loss models, formalize and numerically solve the problem of maximizing the average eMBB bit rate over the set of bit rate levels under the interruption probability constraint.
