Dynamic Downlink Power Control Strategies for LTE Femtocells

In this work, dynamic downlink power control schemes based on user type identification are proposed for LTE (Long Term Evolution) femtocells. In the proposed schemes, the users are distinguished by their serving cells and service types, and the power control is performed accordingly. Moreover, with a variable setting of data rate offset, the proposed schemes can achieve superior performance in terms of a well-balanced data throughput and coverage.
