LTE Macrocell与Picocell共同组网的功率控制干扰协调方案

摘要

Picocell technology is put forward to improve the capacity of LTE system,which relieves the load of Macro eNodeB and helps to solve the ＂blind spots＂ and ＂hot spots＂ problem with extensive concern of the industry.This paper mainly studies the power control algorithms under the Macrocell/Picocell combination networking.Then several feasible power control algorithms are proposed to improve the system performance for the combination networking.Finally,system-level simulation is used for evaluating the performance of these algorithms and the reasons for improving the system＇s throughput are analysed.%微微蜂窝（Picocell）技术是LTE系统为提高通信容量,减轻宏基站的负载量,解决＂盲点＂、＂热点＂区域而提出的,已受到业界的广泛关注。文章主要研究宏蜂窝和微微蜂窝共同组网的功率控制算法。针对于此提出了几种可行的算法来提升系统性能。最后通过系统级仿真验证来评估这几种功率控制算法的性能,并分析其能提高系统吞吐量的原因。
