MODEL FOR ANALYZING PRIORITY ADMISSION CONTROL OF URLLC AND eMBB COMMUNICATIONS IN 5G NETWORKS AS A RESOURCE QUEUING SYSTEM [МОДЕЛЬ СХЕМЫ ПРИОРИТЕТНОГО ДОСТУПА ТРАФИКА URLLC И eMBB В СЕТИ ПЯТОГО ПОКОЛЕНИЯ В ВИДЕ РЕСУРСНОЙ СИСТЕМЫ МАССОВОГО ОБСЛУЖИВАНИЯ]

Ultrareliable and low-latency communication (URLLC) data transmission and enhanced mobile broadband (eMBB) are critical scenarios for the fifth generation (5G) networks. A 5G network resource model was formalized using a triple - radio frequency bandwidth, time slot duration, and the maximum possible power of the transmitted signal. For the scheme of resource occupation which assumes an adaptive change in the signal power and uniform distribution of the time slot between devices, the authors show a conditional distribution of the probabilities of receiving a request for traffic transmission. The model with priority access URLLC and interruption of eMBB service, considering the specified model of resource occupation, is built in the form of a resource queuing system. © 2021 Federal Research Center "Computer Science and Control" of Russian Academy of Sciences.
