| 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.
