In this paper, we address the antenna selection (AS) problem in full-duplex(FD) cooperative non-orthogonal multiple access (NOMA) systems, where amulti-antenna FD relay bridges the connection between the multi-antenna basestation and NOMA far user. Specifically, two AS schemes, namely max-$\SUu$ andmax-$\SUuu$, are proposed to maximize the end-to-endsignal-to-interference-plus-noise ratio at either or both near and far users,respectively. Moreover, a two-stage AS scheme, namely quality-of-service (QoS)provisioning scheme, is designed to realize a specific rate at the far userwhile improving the near user's rate. To enhance the performance of the QoSprovisioning AS scheme, the idea of dynamic antenna clustering is applied atthe relay to adaptively partition the relay's antennas into transmit andreceive subsets. The proposed AS schemes' exact outage probability andachievable rate expressions are derived. To provide more insight, closed-formasymptotic outage probability expressions for the max-$\SUu$ and max-$\SUuu$ ASschemes are obtained. Our results show that while the QoS provisioning ASscheme can deliver a near-optimal performance for static antenna setup at therelay, it provides up to $12\%$ average sum rate gain over the optimum ASselection with fixed antenna setup.
