中文摘要：

带内全双工（in-band full-duplex,IBFD）无线通信允许节点在同一频段上同时进行发送和接收,与传统双工相比理论上最大可成倍提高频谱利用率。分析了IBFD无线全双工通信需要解决的主要技术问题,系统性地归纳了IBFD无线通信研究现状。介绍了IBFD无线通信系统模型和关键技术,特别强调了自干扰消除方法和媒体接入控制（medium access control,MAC）层协议及调度机制的研究。最后结合当前研究和应用热点,提出了未来IBFD无线通信发展趋势和研究方向。

英文摘要：

In-band full-duplex （IBFD） wireless communication, which allows nodes to transmit and receive simultaneously in the same frequency band, can double spectral efficiency theoretically compared with conventional duplex. The survey presents an analysis of the main technical problems of IBFD wireless full duplex communication to be solved, and summarizes the research progress systematically. The system models and key technologies of IBFD wireless communication are introduced, especially emphasizing the research of self-interference cancellation methods, MAC （Medium Access Control） protocols and scheduling mechanisms. Finally, combined with current research and application focuses, the future trends and main research directions of IBFD wireless communication are discussed.
