摘　　要：针对5G等采用全频率复用技术的移动通信系统,获得小区间干扰的近似模型及准确的统计结果对于干扰管理设计具有重要意义。该文提出了基于用户随机位置的干扰模型,该模型中用户随机分布在小区内部,其对相邻小区的干扰因子由用户位置及大尺度衰落等因素共同决定。该文采用等干扰线方法,给出了干扰因子概率密度函数的闭合表达式,并通过蒙特卡洛仿真验证了理论分析结果与仿真分析结果基本完全吻合。Having close modeling and accurate statistics of Intercell Interference(ICI)is of particular interest in the investigation of 5G cellular systems,which employ universal frequency reuse.In this contribution,we propose an ICI model to reflect the practice,by taking into account the combined effects of mobile users’random locations and large-scale fading,including pathloss and shadowing.We also derive the Probability Density Functions(PDFs)of the related ICI Factors(ICIFs)by using the equal ICI lines.Our studies result in the analytical PDFs closely matching the statistics obtained by Monte-Carlo simulations.
