LTE-A增强型小区间干扰协调技术标准化研究

摘要

Heterogeneous network has been considered as one of the most promising techniques for LTE-Advanced system as a result of its considerable improvement of spectrum efficiency,system throughput,and the performance of cell-edge users.In this paper,we give a brief introduction of wireless nodes in heterogeneous network.Then we analyze diverse causes of inter-cell interference in detail.In the end,we summarize the current process of standardization on enhanced inter-cell interference coordination for LTE-Advanced system in the 3rd Generation Partnership Project.%异构网络通过改变网络拓扑结构达到更高频谱利用率、更大系统吞吐量,并能改善边缘用户性能,成为LTE-Advanced关注的主要技术之一。本文主要介绍了无线异构网络中的节点,对造成小区间干扰问题的成因做了重点阐述,并针对3GPP标准化组织关于LTE-A系统增强型小区间干扰协调方案的标准化进度做了总结。
