摘要： The present invention relates to the technical field of wireless communication, and discloses a method for frequency reuse based on cellular network. The method comprises the following steps: dividing the whole cellular network into a plurality of different cell clusters, wherein each cell cluster comprises three cells, every two of them being adjacent to each other; for each cell in a cell cluster, dividing the cell into a central area and an edge area according to the coverage of the cell; dividing the whole available frequency band of the network according to the user distribution and service distribution in the cell cluster; allocating divided frequency bands to the central area and the edge area in the cell cluster respectively according to preset rule; and applying the method for frequency reuse to other cell clusters, thus achieving the frequency reuse of the whole network. With the method, the average spectrum frequency efficiency of the cellular network can be improved, and interference among cells can be effectively suppressed.
