Abstract: 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.
