针对当前CoMP中协作集合选取方案的研究,提出了以用户为中心的动态协作集合选取算法.该算法以最大化小区边缘用户Geometry增益为目标,首先判定网络中的用户类型,其次对CoMP用户反用了调度算法中的最大载干比算法,进而动态地组成协作集合架构,形成当前参与协同传输的最佳协作信道,使得整个簇中的边缘用户都可有序受益.仿真结果表明:本文提出的算法能够在一定程度上改善系统性能.
Concerning the current studies of the Cooperative Set selection,we propose a dynamic user-centric Cooperative Set selection algorithm.The purpose of the algorithm is to maximize the cell-edge users' Geometry gain.Firstly,we identify the user type;secondly,we apply the Max C/I algorithm to an opposite way.Then the architecture of Cooperative Set and the best current cooperative transmission channel is dynamically formed,which makes all the edge users of the whole cluster obtain benefit.Simulation results show that the system performance of the proposed algorithm is improved.
