基于 LTE 系统的上行功率控制方法研究

摘要

The technology that controls the uplink power in LTE system plays an important role in improving the user experience of cell users and network capacity,restraining inter-cell interference,as well as ensuring system performance.Aimming at the limitation of conventional uplink power control method in LTE system,a control algorithm of inner power with the minimum interference is proposed,thus ensuring the minimum singal-to-noise ratio required in communication quality, minimizing overall interference, effectively improving quality of network and system capacity,and promoting users’ experience.%LTE系统的上行链路功率控制技术在提高小区内用户的体验感、提高小区的吞吐量、抑制小区间的相互干扰、以及保证系统性能起着重要的作用。针对现有LTE上行链路功率控制方法的不足，提出一种干扰最小化的内环功率控制算法，使eNode B或用户以最小的功率发射，保证通信质量所需的最小信噪比，使整体干扰最小化，有效提升网络质量和系统容量，提升客户感知度。
