摘　　要：协作多点(coordinated multi-point,CoMP)技术因能有效改善小区边缘用户性能,提高系统吞吐量,引起了业界的广泛关注和研究。CoMP的研究要基于一定的网络架构,目前已有的中心式和分布式网络架构存在回程容量大、CoMP时延高、复杂度高等问题。本文提出了改进型分布式网络架构,在传统分布式网络架构的基础上增加了集中控制的逻辑实体,能有效简化CoMP流程,减少CoMP时延以及实现复杂度。Coordinated multi-point（CoMP） technology can improve both the cell-edge user performance and the system throughput and has aroused widespread concern and study.Studying on CoMP should be based on a certain network architecture,but current central network architecture and distributed network architecture have larger CoMP delay and higher complexity.This paper presents an improved distributed network architecture which adds centralized control logical entities on the distributed network architecture,compares CoMP process of the three network architectures based on the same node selection and resource allocation scheme.Results indicate that the proposed network architecture can simplify CoMP process as well as reduce CoMP delay and implementation complexity.
