Abstract
Fifth-generation (5G) networks are characterized by three use cases - massive machine-type communication (mMTC), ultra-reliable low-latency communication (URLLC), and enhanced mobile broadband (eMBB). Quality of service requirements as well as service parameters within these use cases vary significantly, e. g., URLLC is characterized by an ultralow latency of up to 1 ms, while eMBB has an ultrahigh data transfer rate. The task is to organize the joint provision of such services. The paper proposes a scheme for joint URLLC and eMBB traffic transmission. It is based on the fact that URLLC data has a small volume and can occupy less than one physical resource block. The authors analyze the scheme using the developed retrial queuing system with two orbits - one for temporary storage of interrupted eMBB users and the other for eMBB users waiting for service to start. The authors propose the matrix geometric algorithm for calculating the probability distribution as well as formulas for probabilistic characteristics.
