Coordinated multi-point(Co MP) transmission has been regarded as a fascinating technology for4 G wireless communication systems. In this paper, the Co MP dynamic clustering problem is studied, a Friends algorithm(F-A) is proposed based on the procedure of making friends in human society, and then a dynamic clustering scheme is proposed based on F-A. The mutual interference among cells of the network is considerate in this algorithm, which can be obtained by CSI feedback.Compared to Traversal search(T-S) algorithm, the proposed algorithm has lower computational complexity, and the performance is almost equal. Simulation results show the proposed scheme is effective for dynamic clustering.
