Model of radio admission control for URLLC and adaptive bit rate eMBB in 5G network

In today's rapidly developing telecommunications technologies, mobile communication services are widely penetrating into all segments of society. The 5th generation network (5G) will cover a broader range of usage scenarios - enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). This paper considers a model of joint service of URLLC and eMBB traffic within a single base station. The first type of traffic is supposed to have priority due to its high latency requirements, while the second type of traffic has a high speed. If there are no available resources to serve URLLC traffic, the allocated resources for eMBB traffic will decrease until they are completely withdrawn. We model the above mentioned system as a queuing system with the bit rate degradation and service interruption. © 2021 Copyright for this paper by its authors.
