Probability-Based User Management Algorithm for the Hybrid NOMA System

In this paper, a novel hybrid non-orthogonal multiple access (NOMA) system that combines the cooperative NOMA (C-NOMA), original NOMA, and orthogonal (OMA) is investigated. The probability-based user management algorithm (PUMA) proposed for considered with regard to fulfilling requirements of 5G beyond communications, which joint transmission mode selection pairing scheme. effective region stochastic geometric model introduced measure users C-NOMA in all are distributed as an independent homogeneous Poisson point process. exact coverage outage probabilities derived closed-forms under more realistic network scenarios, involved characteristics both channel distance users. Furthermore, these not only utilized PUMA, but also can be applied performance NOMA-related systems. Monte Carlo simulation executed verify mathematical derivations. Simulation results demonstrate PUMA possesses higher spectrum utilization, efficiency, better comparison random coordination
