Abstract

In this paper, we propose and evaluate a new interference co-ordination scheme for the uplink of LTE systems. This presented approach mitigates the effects of ICI (Inter-Cell Interference) by finding suboptimal frequency and power assignments to all users in a given cellular network. The spectral efficiency of cell-edge users is enhanced in this scheme and simulation results show that our presented approach outperforms Samsung’s Flexible Fractional Frequency Reuse (FFFR) algorithm which is one of the interference coordination schemes proposed for LTE systems.
LTE系统中的上行干扰协调/避免
在本文中,我们提出并评估了一种新的LTE系统上行干扰协调方案。该方法通过寻找给定蜂窝网络中所有用户的次优频率和功率分配,减轻了ICI(细胞间干扰)的影响。该方案提高了蜂窝边缘用户的频谱效率,仿真结果表明,该方法优于三星的柔性分数频率复用(FFFR)算法,该算法是LTE系统中提出的干扰协调方案之一。
