Abstract

This paper proposes a new joint power control and resource allocation algorithm in cognitive LTE femtocell networks. The presented algorithm minimizes the transmit power of each femtocell, while satisfying a maximum number of users with QoS requirements. The optimization problem is multi-objective NP-hard. Hence, in the paper a joint channel assignment and power control allocation scheme is proposed, solving the problem so formulated. Especially, a Gale-Shapley method is involved in this scheme to address the co-tier femtocell interference issue. In order to find a pareto optimal solution, a weighted sum is used. The performance of this method is evaluated by simulation.
