| Abstract: | The Unmanned Aerial Vehicle (UAV) can provide convenient and effective supplementary communication solutions for 6G networks since it gets the advantages of flexibility, adaptability and high mobility. To improve further the spectrum efficiency and reduce the transmission time required for full data exchange, a Full-Duplex (FD) Multi-Way Relay Network Non-Orthogonal Multiple Access (NOMA) transmission scheme (FD NOMA MWRN) is proposed. In addition, a more practical case is assumed that in-phase/quadrature imbalance of transceiver is taken into account. Based on this, the transmission rate and energy efficiency are analyzed. The simulation results indicate the following conclusions. Firstly, the full-duplex transmission can improve the spectral utilization compared to the Half-Duplex (HD) mode. Secondly, the proposed scheme, which consumes the number of time slots is always one regardless of the number of users, has better performance than the Orthogonal Multiple Access (OMA) scheme. Thirdly, the In-phase/Quadrature (I/Q) imbalance and the working height of the UAV both limit the transmission rate of the system. |
