Query: Joint Resource Block-Power Allocation for NOMA-Enabled Fog Radio Access
  Networks   In order to achieve efficient communication in the fifth generation (5G)
networks, non-orthogonal multiple access (NOMA) technique has been utilized in
fog radio access networks (F-RANs). In this paper, we investigate the resource
allocation problem in a NOMA-enabled downlink F-RAN. To maximize the weighted
sum rate of NOMA users served by fog-computing-based access points (F-APs), the
resource block (RB) allocation and power allocation are optimized.
Specifically, we decouple the problem into RB allocation and power allocation
problems. The former is modeled as a many-to-one matching game and we propose a
modified swap-enabled matching algorithm to solve it, which takes interference
threshold into consideration. The later is a non-convex problem, we transform
it into a tractable one via some approximations and get the closed-form
expressions of power allocation coefficients. Finally, we combine the both to
propose a joint resource allocation algorithm, which is preformed iteratively
to obtain the optimal result. Simulation results are provided to show the
performance of the algorithm.
