Abstract
As wireless communications experience exponential growth,
energy consumption has became a crucial problem in the
wireless industry. Energy efficiency of wireless systems
has to be significantly improved in order to guarantee
the sustainable growth of the wireless industry. Plenty
of efforts have been carried on to achieve so called
green wireless world. In this paper, focusing on energy
saving in wireless access networks, we provide an
overview on energy saving studies currently conducted in
3GPP LTE standard body. The aim of the paper is to gain a
better understanding on energy consumption problems in
wireless access networks and identify key research
problems in this field. Currently most of research focus
on base station energy saving with efforts to reduce
energy consumed by power amplifiers. Less attention are
spent on the network level. We believe a holistic network
level solution based on novel architecture and methods,
such as relay, user cooperation, as well as cognitive
approaches, will be prosing enablers towards green
wireless access networks.
