Abstract: With explosive growth of high-data-rate applications, more and more energy is consumed in wireless networks to guarantee quality-of-service (QoS) requirements. Therefore, energy-efficient communications have been paid increasing attention under the background of limited energy resources and environmental-friendly transmission behaviors. In this article, basic concepts of energy-efficient communications are first introduced and then existing fundamental works and advanced techniques for energy efficiency (EE) are summarized, including cellular network deployment, orthogonal frequency division multiple access (OFDMA) networks, multiple-input multipleoutput (MIMO) techniques, relay transmission, and resource allocation for signaling.
