Multi-cell cooperation has been regarded as a promising technique of the future cellular wireless network to achieve higher transmission rate and better QoS (Quality of Service) performance. Cooperation among base stations can be classified into two categories: centralized and distributed cooperation. In this paper, the authors mainly consider efficient and practical cooperation clustering approaches in the downlink Coordinated Multi-Point (CoMP) system. A novel Multi-Layered clustering method is proposed for distributed cooperation, which is able to make a significant enhancement with limited overhead increment compared with traditional static clustering.
