中文摘要：
针对4G移动通信系统提出的提高频谱利用率、同频组网的需求,文章从频率复用问题入手,提出了一种软分数频率复用方案。软分数频率复用方案包括3种表现形式,在实际应用中,可以根据物理层链路增益选择适当的表现形式。文章以第2种表现形式为例介绍了采用该方案的频率复用方法。研究表明,使用软分数频率复用方案,系统的频率复用系数可以达到1/3～1。软分数频率复用方案解决了同频组网问题,并已经在上海4G实验网中得到了良好的应用。
英文摘要：
A soft fractional frequency reuse scheme is proposed to fulfill full frequency reuse for the 4G mobile communications system. This scheme can be implemented in three types, which could be chose in practical applications according to the link gain of the physical layer. The implementation of soft fractional frequency reuse in one of the three types is studied. The study results show that the frequency reuse factor of this scheme may reach 1/3-1. The simplified form of this scheme has been applied in the 4G experimental network in Shanghai successfully, and provides a way to fulfill full frequency reuse in systems.
