%X 在LTE多小区蜂窝系统中，负载不均衡和用户不均匀给系统带来较大干扰。为解决此问题，提出了一种新的资源划分方法：时域资源划分方法。该方法把时域划分和软频率结合起来，在原则上保证了小区内不存在干扰，也从根本上保证了相邻小区间边缘用户不会产生干扰。仿真表明，这种时域资源划分方法能够适应负载不均匀的情况，与传统的软频率复用相比，较大地提升系统的吞吐量。<br>In LTE multi cell cellular system,the unbalanced load and the user distribution bring serious inter cell interference to the system.To solve this problems,we propose a new resource allocation scheme based on modified fractional time reuse（MFTR）.This scheme combines time domain division with soft frequency to ensure there is no inner interference,but also guarantee no interference with the adjacent cell.Simulation results show that this method can not only adapt to the load uneven situation,but also greatly enhances the throughput of the system comparing with the traditional soft frequency reuse
