在异构网（Het-net）热点区域覆盖的场景下，各种干扰将会变得异常复杂。为了减少边缘用户之间的相互干扰，上行功率控制技术需要得到有效的运用。本文首先对传统的上行功控技术进行了相关的理论分析，然后针对引入低功率节点后系统出现的新特性，提出了在热点区域覆盖场景下一种新的基于系统吞吐量最大化原则的上行功控方法。通过系统仿真进行了验证，结果表明改进方法较传统方法的边缘用户吞吐量以及系统平均吞吐量都有一定程度的提升。

In Het-net,the interference scenario becomes complicated. In order to reduce mutual interference of edge users,uplink power control must be used effectively.In this paper,the limitation of traditional uplink power control method is analyzed.In order to improve the uplink power control efficiency,a novel uplink power control method based on maximize the system throughput is proposed.The novel method is simulated by system simulation.The edge user throughput and system average throughput is improved in different degree respectively.
