REM-based power control and femtocell self-organization

This paper focuses on femtocell self-organization through radio environment map (REM) based power control. Different downlink power control strategies with REM have been studied with realistic LTE system evaluation. We have shown that downlink power control can be an effective means for femtocell self-organization. With the help of REM information, the performance between macrocell and femtocell is better balanced. Our study suggests that REM-based power control is useful in practical femtocell network planning, in which a careful balance should be struck in maintaining satisfactory network performance and user QoS (quality of service) in heterogeneous networks.
