| 摘 要： | 干扰管理是异构网络(heterogeneous network,HetNet)中的重要研究热点.介绍了不同干扰产生的原因及其分类,分别从无线通信中的时域资源、频域资源与空域资源3个角度出发,介绍了小区间干扰协调管理(inter-cell interference coordination,ICIC)、增强型小区间干扰协调管理(enhanced inter-cesll interference coordination,eICIC)、多点协作传输(coordinated multipoint processing,CoMP),并基于这3个角度综述了国内外在长期演进(long term evolution,LTE)网络架构下实施干扰管理的主要方案.通过表格从系统复杂度、公平性、集中式/分布式等角度对不同方案进行分析与评估,并使用示意图和流程图对特色算法进行深入分析,指出各类方案的使用环境、技术特点以及不足之处.依据当前通信技术的研究热点方向及第5代移动通信技术(5G)的发展趋势,对未来干扰管理方法的发展方向进行预测.

| Abstract: | Interference management is an important part of HetNet system. In this paper, we describe the causes and the classifications of various interference, and present ICIC, elCIC, CoMP in time domain, frequency domain and spatial domain respectively. Then, some typical interference management schemes are introduced and compared through forms, diagrammatic sketch and flowcharts. We also summarized the characteristics, suitable environment and deficiencies of these schemes. At last we talked about the future research direction base on the current hotspot technology in communication research field and the development trends of 5G. |
