This work focuses on the design of a novel architectural design of a software-defined networking (SDN) virtual Fog computing based radio access network (Fog-RAN). Specifically, designing an optimal dynamic radio resource allocation to handle the fluctuating traffic loads is critical. We jointly study radio resource allocation and transmit beamforming to improve resource utilization and users' satisfaction, by minimizing the network power consumption (NPC) and maximizing the achievable sum-rate (ASR), simultaneously. We first formulate a mixed-integer nonlinear problem (MINLP) to optimize the physical resource block (PRB) allocation, the assignment of user equipments (UEs) and radio unit (RU), and the downlink transmit beamforming, by considering imperfect channel state information (CSI). To solve the intractable MINLP, we exploit the successive convex approximation (SCA) approach. Then, we formulate a multiple knapsack problem (MKP) to optimize the assignment between RUs and virtual baseband units (vBBUs), by exploiting the set of active RUs minimized in the previous problem. We solve the formulated MKP by decomposing the dual problems and solving them through the dual descent (DD) method. Through performance analysis, we show the proposed approach provides a high users' satisfaction rate, maximizes the ASR and minimizes the NPC, and provides better savings, in terms of the number of radio and baseband resources utilized, than its counterparts.
