摘要
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e Node 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。
The technology that controls the uplink power in LTE system plays an important role m 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.
