Abstract: Fifth generation (5G) wireless networks are characterized by joint transmission of ultrareliable low-latency communications (URLLC) and enhanced mobile broadband (eMBB). URLLC is often small in size and can take up part of a resource block. The paper analyzes a scheme for joint URLLC and eMBB transmission in the form of a queuing system with priority admission control with the ability to reduce bit rate and interrupt eMBB transmission when URLLC arrives. Numerical analysis of the problem of selecting eMBB traffic transmission rate levels to maximize the eMBB bit rate taking into account restrictions on the eMBB blocking and service interruption probabilities was performed.

Keywords: 5G, eMBB, URLLC, queuing system, priority admission control, interruption, bit rate degradation.
