Interference management is one of the most important issues in two-tier femtocell networks in which a central macrocell underlaid with several femtocell hotspots. To address the cross-tier and co-tier interference, this paper introduces an energy-efficient power control algorithm via convex pricing scheme, where both circuit and transmit power have been considered. To achieve the target SINR, the...
In two-tier femtocell networks, where a central macrocell underlaid with femtocells, femtocells may cause serious interference and consume large amounts of energy for its large-scale application. To solve the problem this paper presents an energy-efficient power optimization for two-tier femtocell networks in the analytical setting of a game theoretic framework, where both circuit and transmission...
