Abstract :
In the near future, a large diffusion of LTE femtocell devices is expected due to their simple installation and advantages in terms of high throughput. This deployment model leads to a harmful interference in both macro and femtocell tiers and to a substantial increase of energy consumption on entire cellular network. In this paper, we present a fully distributed power control algorithm for LTE heterogeneous networks, in which Femto Base Stations (FBSs) adapt their pilot power, and thus the coverage, to the onsite traffic demand. We show the stability of our algorithm under variable traffic conditions and quantify the energy saved by the entire femtocell network in a case study.
