摘　　要：近年来,随着智能终端数量的增长与第五代移动通信技术的发展,移动通信系统对系统频谱效率以及数据吞吐量的需求越来越高。因此,如何能提升未来无线移动通信系统频谱效率成为了5G研究的重点方向。在第五代无线移动通信新空口技术(5GNR)研究进程中,协作多点传输技术(CoMP)通过其多个传输点的联合传输,降低小区间干扰(Inter-cell Interference),从而提升小区边缘用户的覆盖性能,实现了网络容量以及频谱效率的大幅提升。另一方面,全维度大规模多输入多输出技术(FD Massive MIMO)充分运用了FDMIMO的维度资源、波束赋形以及角度调整技术以及MassiveMIMO的大规模的天线跟波束资源,进一步实现了网络频谱效率的提升。本文在FD Massive MIMO协作多点传输场景下深入研究了提升系统频谱效率的算法,通过对比分析总结出一种有效提升频谱效率并同时实现干扰协调的算法。最后,给出了系统级仿真结果并证明了该算法在提升系统频谱效率方面的优越性能。In recent years,with the increase of the number of intelligent terminals and the development of the fifth-generation mobile communication technology,the demand of the mobile communication system for the system spectrum efficiency and data throughput is increasingly high.Therefore,how to improve the spectrum efficiency of future wireless mobile communication system has become the focus of 5G research.In the research process of 5G NR,coordinated multipoint transmission technology(CoMP)reduces inter-cell interference through the joint processing of multiple transmission points,thus improving the coverage performance of cell-edge users,and achieving a significant increase in network capacity and spectrum efficiency.On the other hand,FD Massive MIMO makes full use of the dimensional resource beamforming and beam angle adjustment technology of FD MIMO and the Massive antenna and beam resources of Massive MIMO,which further realizing the improvement of network spectral efficiency.In this paper,under the background of FD Massive MIMO CoMP,the algorithm of improving the spectral efficiency of the system has been studied.Through comparative analysis,an algorithm that can effectively improve the spectral efficiency and achieve interference coordination was summarized.Finally,the system level simulation results are given and the superior performance of the algorithm in improving the spectrum efficiency of the system is confirmed.
