An Overlapped Clustering Scheme of Coordinated Multi-Point Transmission for LTE-A Systems

摘要：

　　In this paper,we propose an overlapped clustering scheme to decide the cooperation cells for coordinated multipoint (CoMP) systems.In the scenario of joint processing of CoMP,the cooperated cells jointly transmit for users so the intercell interference among the cooperation cells are eliminated.However,the cluster-edge users suffer from the inter-cluster interference.The overlapping patterns are defined for the cluster-edge users to make sure that these users become the overlapping cluster-center users.Then the overlapping patterns and clusters are allocated orthogonal frequency resource,which can cancel inter-cluster interference and improve the performance of cell-edge users.Simulation results show that the proposed overlapped clustering scheme yields significant improvement to cell-edge usersspectrum efficiency as well as increasing average cell throughput.
