Energy Efficiency of Cell Range Extension of Picocell

Article Preview

Abstract:

Energy efficiency is an important issue in the wireless communication system as the increasing number of wireless network users and the emerging data usage. Heterogeneous network (HetNet) is a possible way to reduce the energy consumption since the distance between user equipment (UE) and the base station is shortened in HetNet, which sharply reduce the pathloss between the transmitter and receiver. This paper investigates the energy efficiency of Pico-Macro system in terms of Joule per bit. A effects of using Cell Range Extension (CRE) of Picocell based on energy efficiency is investigated and verified through the simulation results.
