Fifth generation mobile communications system (5G) that enables large transmission capacity (over 10 Gbps) is currently standardized and under development. Non-orthogonal multiple access (NOMA) scheme is a typical core technology for 5G. On the other hand, we had proposed earlier a chaos multiple-input multiple-output (C-MIMO) transmission scheme that harnesses the strengths of the chaos communication system. C-MIMO exhibits channel coding effect and physical layer security based on a common key encryption that helps realize a secure wireless transmission. Furthermore, based on the C-MIMO, we had proposed a downlink chaos NOMA transmission scheme that realizes physical layer security in NOMA. However, in the conventional studies, an uplink transmission is not considered yet. Therefore, in this paper, we propose an uplink chaos NOMA transmission scheme using C-MIMO to realize a secure and large-capacity uplink transmission. The performance of the proposed scheme is evaluated through numerical simulations.
