| 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 Frequency Reuse(SFR) scheme in which the Frequency Reuse Factor(FRF) is three to suppress co-frequency interference among neighbor cells,but it exists still space to improve in areas of peak rate and system capacity.So this paper introduces a SFR scheme in which FRF is seven.It can raise the peak rate greatly for users in edge areas of a cell and increase system capacity by combining with adaptive resource scheduling strategy. |
