Abstract

Effective sharing of spectrum resources is essential in forthcoming sixth-generation (6G) wireless networks to deploy massive Internet-of-Things (IoT) terminals. Unmanned aerial vehicles (UAVs) can significantly support IoT devices, especially in remote or disaster areas. Recently, power-domain non-orthogonal multiple access (PD-NOMA) utilized with underlay spectrum sharing has been proposed as a promising solution to enhance spectral efficiency. However, in a UAV-enabled multi-user spectrum sharing network, the risk of wiretapping in uplink signaling should be studied to ensure secured communications. This article investigates the uplink secrecy performance of a UAV-supported PD-NOMA-based underlay spectrum sharing (PDN-USS) network. The system is principally comprised of a secondary network with a pair of IoT terminals and a UAV receiver, where imperfect successive interference cancellation is carried out to decode data. Considering a transmission power constraint imposed at the secondary transmitters, we derive the closed-form expressions of the secrecy outage probability (SOP) for both IoT terminals. All the analytical expressions are obtained considering all the links undergo Nakagami-m fading. The simulation results validate the accuracy of the analysis and confirm that the PDN-USS system outperforms the benchmark OMA-based USS scheme in terms of the SOP. The results also provide valuable insights into the impact of the interference temperature and residual interference on the uplink SOP.
