基于移动宏用户距离估计的家庭基站功率控制

Femtocell Power Control Based on Distance Estimation of Moving Macrocell User Equipment

家庭基站是一种可在室内灵活配置、低功率的无线接入点,能够以较低功率为用户提供大带宽、高速率的服务。而家庭基站的密集部署产生了干扰问题,如何有效地管理干扰是当前家庭基站研究的关键问题。在一个移动宏用户穿越家庭基站覆盖范围的场景中,以保障其SINR为目的,设计了一种估计其与家庭基站距离来控制功率的方案,并通过仿真证明其有效性。

Femtoeell is a low power wireless aecess point that can flexible configuration in door, it can provide large bandwidth high rate service to users with a low power. The intensive deployment of femtoeell brings interference problems. How to effectively manage interference is the key problem of the current research of femtocell. This paper bases on a kind of femtocell power control scheme that estimates the distance of MUE and femtocell in a scene of moving MUE crossing femtocell, in order to ensure its SINR,and the simulation results prove its validity.
