- In this paper, we propose an energy efficient power control scheme, called the distributed and intelligent power control (DIPC), to increase downlink (DL) system throughput and reduce energy consumption for femtocell base station (fBS) Tx power in the LTE-Advanced femtocell networks. In the DIPC scheme, a scheduler in each fBS allocates resource blocks (RBs) with optimal Tx power obtained by the requested data rate for each femtocell user equipment (fUE). The simulation results show that the DIPC scheme outperforms the conventional fixed power (CFP) scheme which uses fixed Tx power in terms of system throughput for the macro user equipments (mUEs) and fUEs as well as energy consumption for fBS Tx power. © Springer Science+Business Media Dortdrecht 2012.
