  Abstract: By employing the advances in wireless cloud technologies, this letter establishes a centralized-distributed optimization architecture for spectrum access in small cell networks. In the centralized aspect, the spectrum access problem is solved in the cloud. In the distributed aspect, the problem is solved by a game-theoretic solution, aiming to address the challenges of heavy computation complexity caused by the densely deployed small cells. The properties of the game, including the existence of pure Nash equilibrium and the achievable lower bound, are rigorously proved and analyzed. Furthermore, a cloud-assisted best response learning algorithm with low computational complexity is proposed, which converges to the global or local optima of the aggregate interference level of the small cell network. It is shown that the cloud-assisted algorithm converges rapidly and is scalable when increasing the number of small cells. Finally, simulation results are presented to validate the proposed cloud-based centralized-distributed solution.
