Abstract
Full-duplex (FD) has the potential to double the resource utilization of cellular networks by enabling simultaneous transmissions in the uplink (UL) and downlink (DL) directions using the same time and frequency resource. Several challenges arise from integrating FD with non-orthogonal multiple access (NOMA) networks. This chapter focuses on the resource optimization challenges in full-duplex NOMA networks, as well as the practical challenges of incorporating in-band full-duplex (IBFD) base stations within NOMA networks. In particular, the problems of UL and DL dynamic resource optimization, mode selection, and power allocation are discussed. Moreover, the objectives and tools of FD-NOMA network optimization are presented. Subsequently, the chapter surveys the state of the art on FD-NOMA, and highlights the existing works’ modelling, objectives, and methodologies. Finally, the chapter provides numerical results and discusses the open problems of FD-NOMA cellular networks.
