摘要:
为提高系统性能,LTE系统可通过频率复用因子(Frequency Reuse Factor,FRF)为 3的软频率复用(Soft Frequency Reuse,SFR)方案来有效抑制小区间的同频干扰,但在小 区峰值速率和系统容量方面仍有改善空间,由此介绍一种FRF为7的SFR方案,并结合与之相 适应的资源调度策略,可较大地提高小区边缘用户的峰值速率,使系统容量得以提升。

Abstract:
In order to improve system performance, LTE systems usually adopt a Soft Freque ncy Reuse(SFR) scheme in which the Frequency Reuse Factor(FRF) is three to suppress co-frequency interference among neighbor cells, but it exist s still space to improve in areas of peak rate and system capacity. So this pape r introduces a SFR scheme in which FRF is seven.It can raise the peak rate greatly for user s in edge areas of a cell and increase system capacity by combining with adaptiv e resource scheduling strategy. 
