近年来，电池供电的移动的设备，例如，智能手机、平板电脑、传感器和膝上型电脑的发展，导致对具有高能效的高容量无线通信的显著需求。能够实现这种效率的技术包括全双工无线通信，其基于利用有限频率资源的同时上行链路和下行链路数据传输。以前关于全双工无线的研究主要集中在使网络容量加倍，而在本文中，我们讨论全双工无线如何也可以提高能源效率。我们提出了低功耗通信的无线全双工（LPFD），利用这一事实，即在全双工通信的持续时间是半双工通信的一半。在LPFD中，通过使用无线通信终端中的收发器被关断的睡眠状态，无线通信终端的功耗被降低，并且能量效率被提高。
Recent years have witnessed a proliferation of battery-powered mobile devices, e.g., smartphones, tablets, sensors, and laptops, leading to a significant demand for high capacity wireless communication with high energy efficiency. Among the technologies capable of such efficiency is full-duplex wireless communication, based on the simultaneous uplink and downlink data transmission with limited frequency resources. Previous studies on full-duplex wireless mostly focused on doubling the network capacity, whereas in this paper we discuss how full-duplex wireless can also increase the energy efficiency. We propose low-power communication by wireless full-duplexing (LPFD), taking advantage of the fact that in full-duplex the duration of communication is half that of half-duplex communication. In LPFD, by using the sleep state in which the transceiver in the wireless communication terminal is turned off, the power consumption of the wireless communication terminal is reduced, and the energy efficiency is improved.
