Abstract

By constructing the cliques of the compatibility graph, the heuristic spectrum sharing (SS) method is proposed to enable opportunistic frequency reuse between two networks possessing the adjacent bands in the centralized manner. With the method, the minimal satisfaction of cells is maximized and the spectral utilization is improved. However, the method suffers the prohibitive complexity, especially if the number of cells is large. To cope with the complexity, the suboptimal SS method has been developed with the same principle. Simulations reveal that the suboptimal SS method can provide similar performance in terms of spectral utilization and minimal satisfaction to the heuristic solution.
