| 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。

| 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. |
