自干扰消除技术的最新进展实现了带内全双工无线系统，其以高频谱效率在相同频带中同时发送和接收。作为带内全双工无线通信的一种典型应用，带内全双工中继技术是一种集带内全双工无线通信和中继技术优点于一身的新型通信技术。然而，一些重大的研究挑战仍然有待解决之前，其广泛的部署，包括小尺寸全双工设备的设计，信道建模和估计，跨层/联合资源管理，干扰管理，安全性等，在本文中，我们提供了一个简要的调查已经做了一些工作，带内FDR，并讨论了相关的研究问题和挑战。我们确定了带内FDR的几个重要方面：基础知识，使能技术，信息理论性能分析，关键设计问题和挑战。最后，我们还探讨了带内FDR的一些更广泛的前景。
Recent advances in self-interference cancellation techniques enable in-band full-duplex wireless systems, which transmit and receive simultaneously in the same frequency band with high spectrum efficiency. As a typical application of in-band full-duplex wireless, in-band full-duplex relaying (FDR) is a promising technology to integrate the merits of in-band full-duplex wireless and relaying technology. However, several significant research challenges remain to be addressed before its widespread deployment, including small-size full-duplex device design, channel modeling and estimation, cross-layer/joint resource management, interference management, security, etc. In this paper, we provide a brief survey on some of the works that have already been done for in-band FDR, and discuss the related research issues and challenges. We identify several important aspects of in-band FDR: basics, enabling technologies, information-theoretical performance analysis, key design issues and challenges. Finally, we also explore some broader perspectives for in-band FDR.
