摘要
Coordinated Multiple-Point (CoMP) technology is one of the most important technologies in ultra-dense networks (UDN). Effective CoMP clustering algorithm can provide additional gain for system performance, such as higher system throughput and spectral efficiency (SE) for cell-edge users. This paper, a novel dynamic clustering scheme based on spectral clustering in graph theory for CoMP-user is presented to maximize system SE and cell-edge users' throughput. Our proposed scheme mainly consists of weight design, graph construction and spectral clustering that can achieve good performance and low complexity. Simulation results show that the proposed algorithm yields significant gains of SE and throughput and low running time compared with some existing clustering schemes.
