Planning and control of LTE femto networks

Adaptation of LTE femtocell transmission power levels in a distributed architecture to meet performance requirements is crucial for successful femtocell network deployment. System stability, scalability, robustness, and controllability must be addressed before large scale deployment. This paper proposes and analyzes a new method for dynamically adjusting LTE femtocell power levels to mitigate interference to meet user selectable network performance goals. The paper proves that the proposed method converges to feasible solutions. The proposed algorithm is suitable for both distributed femtocell control and centralized policy enforcement.
