Abstract

In the last decade, the wireless inband full-duplex (FD) communications have been extensively studied to make a better use of available spectral resources. The FD communication allows the simultaneous transmission and reception on the same frequency band within the same device, which theoretically doubles the spectral efficiency. Moreover, FD multiple user communication assisted by spectral efficient bidirectional relays provides better coverage, better diversity gains, and improved capacity performance. This chapter examines the recent works done in the area of mobile multi-user FD relaying systems from the physical layer perspective. This chapter begins with the comparison of traditional half duplex techniques with the recently developed FD radios and the modeling of residual self-interference at the FD node. Further, recent works related to the half-duplex and/or FD, two-way and/or one-way relaying where the impact of user mobility is taken into account are discussed in detail. Moreover, this chapter surveys the multi-user systems, and the performances of various multi-user scheduling schemes are compared in detail. Finally, this chapter includes some applications of FD relaying with short-packet communication for its possible applications in mission-critical applications such as virtual reality, autonomous driving, telemedicine, etc.
