This paper analyzes the integration of Non-Orthogonal Multiple Access (NOMA) in a Fog Radio Network (FRAN) architecture with limited fronthaul capacity. More precisely, it proposes methods for optimizing resource allocation downlink NOMA-based FRAN multiple blocks (RB). The problem is formulated as mixed-integer optimization problem, which determines user-to-RB assignment, power allocated to each RB, and split levels NOMA users served by RB. maximizes network-wide rate-based utility function...
