doi:10.3969/j.issn.1000-0801.2010.05.004

摘要/Abstract

摘要：

LTE系统采用更灵活的频率复用策略，任何一个小区都有可能使用所有的频谱资源，因此小区间的干扰不可避免。本文从干扰协调和干扰消除两方面介绍了LTE小区间干扰抑制的最新研究成果，对学术界及3GPP标准提案中的主流算法进行了综合评述。最后，结合LTE 标准的演进，分析了LTE系统小区间干扰抑制技术的发展趋势。

关键词: 小区间干扰, 干扰抑制, 协作调度

Abstract:

LTE systems applied more flexible frequency re-use strategies. All cells in LTE systems are possible to use the whole spectrum resource，which makes inter-cell interference unavoidable. In this paper we review the major 3GPP proposals and academic research of inter-cell interference mitigation，mainly in two categories of interference coordination and interference cancellation.New techniques for inter-cell interference mitigation in LTE evolutions are also investigated.

Key words: inter-cell interference, interference mitigation, cooperative scheduling
