摘要： The present invention discloses a cell clustering method, used to classify multiple small cells into N clusters and including the following steps: based on throughputs, respectively placing N small cells having a largest interference with each other into the N clusters to initialize the clusters; and based on the throughputs, separately adding a small cell having a smallest interference with the clusters into the clusters, and repeating the step until all the small cells are allocated into the clusters. The present invention further discloses a spectrum overlapping multiplexing method based on the cell clustering method. According to the present invention, the cell system average spectral efficiency and the cell edge spectral efficiency in an ultra dense network can be improved.
