Our paper UAV-Assisted Cooperative & Cognitive NOMA: Deployment, Clustering, and Resource Allocation has been accepted for publication in Transactions on Cognitive Communications and Networking. We describe how the deployment of an unmanned aerial vehicle (UAV) can be used as a relay that fairly serves many secondary users in a hot-spot region.
The cooperative and cognitive non-orthogonal multiple access technologies are an inherent remedy to achieve high spectral efficiency at large-scale networks. Moreover, considering the expeditious 3D deployment capabilities of UAVs, their use as cooperative relays paves the way for enhanced network performance. In this paper, we consider UAV-assisted cooperative and cognitive non-orthogonal multiple access technologies to improve the wireless spectrum efficiency by fairly serving multiple users on the same resource. We develop a UAV deployment algorithm that jointly accounts for user clustering, channel assignment, and resource allocation sub-problems. Besides, the results in the paper demonstrate that the optimization needs to take into account inevitable real-time imperfections to accommodate a practical communication system.
