摘　　要：近年来,随着全球能源消耗和温室气体排放量的不断增长,节能减排的问题引起了全社会的密切关注。在无线通信领域,产业界和学术界也展开了对通信系统节能问题的大量研究。通信系统中,中继的引入可以扩大基站覆盖范围、消除覆盖盲点、提高系统性能;同时,中继可以将较长的通信距离分为较短的两段或多段距离进行逐段传输,大大降低了传输功耗,因此中继传输具有天然的节能潜力。本文针对高能效中继通信技术,介绍了中继网络的能耗模型,并从链路到网络对高能效中继技术的研究点进行了综述与展望。In recent years, with the growth of the global energy consumption and greenhouse gas emissions, the energy saving problem has aroused close attention of the whole world. In the field of wireless communications, the industry as well as the academia has paid increasing attention to the energy efficient communications. In the wireless communication systems, relayed transmission has become an effective way to increase the coverage, throughput and transmission reliability of the networks. Meanwhile, a long transmission distance can be divided into two or more short pieces by relay, which can largely reduce the transmission power consumption; as a result, relayed transmission has the natural energy-saving potential. Energy-efficient relay communication technology was introduced, including the power consumption model of the relay network, energy efficient relay link and energy efficient relay network.
