标题： Cooperative Strategies for Wireless-Powered Communications: An Overview

摘要： 射频（RF）能量传输和收集近年来受到了广泛关注，作为一种有前景的方法，可以显著延长能源受限的无线网络的寿命。 这项技术有很大的潜力为设备提供相对稳定和连续的射频能量；因此开启了一种新的研究范式，称为无线供电通信（WPC），这带来了许多具有广泛应用的新研究机会。 其中，针对高效WPC的协作方案的设计与分析如今引起了极大的研究兴趣。 本文综述了WPC的各种协作策略，特别强调了用于无线供电协作通信的中继协议、用于认知无线供电网络的协作频谱共享方案，以及用于无线供电安全通信的协作干扰策略。 在结束本文之前，我们还识别了该领域的一些有趣的研究方向。 显示英文摘要

摘要： Radio frequency (RF) energy transfer and harvesting has been intensively studied recently as a promising approach to significantly extend the lifetime of energy-constrained wireless networks. This technique has a great potential to provide relatively stable and continuous RF energy to devices wirelessly; it thus opened a new research paradigm, termed wireless-powered communication (WPC), which has raised many new research opportunities with wide applications. Among these, the design and analysis of cooperative schemes towards efficient WPC have attracted tremendous research interests nowadays. This article provides an overview of various cooperative strategies for WPC, with particular emphasis on relaying protocols for wireless-powered cooperative communications, cooperative spectrum sharing schemes for cognitive wireless-powered networks, and cooperative jamming strategies towards wireless-powered secure communications. We also identify several interesting research directions in this area before concluding this article.
