ABSTRACT: With the continuous increase of user requirement, the
Information and Communication Technology (ICT) has developed rapidly. As a result,
both capacity and coverage performances have been improved, and at the same time,
the communication networks have been more energy-intensive. In order to improve
the energy efficiency of cellular networks, the green communication must be realized
in the future networks. In this article, we present a short survey on energy-efficient
technology of cellular networks. Moreover, we classify them into three categories
based on theirapplication scenarios: energy-efficient architectures, energy-efficient resource management
and energy-efficient radio technologies. For the first scenario, the applications
of relay, Coordinated Multiple Points (CoMP) and heterogeneous network
are discussed in detail. For the second scenario, the switching off scheme will
be introduced as an emphasis of this part. And for the third scenario, the Multiple-Input
Multiple-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) will
be introduced as the representatives of the Energy-Efficient
Radio Technologies. Finally, based on the technologies introduced above, a prospect
forecast of the energy-efficient wireless cellular network is presented.
