Abstract (in Japanese) (See Japanese page) 
(in English) Recently, standardization of the 5th generation mobile communication system (5G) is actively processed to aim for commercialization in 2020. Furthermore, in beyond 5G, it is expected to accommodate a large number of user terminals than those expected in 5G, and a corresponding increase in mobile traffic will be accompanied. In such a wireless communication environment, physical layer security is also important for non-orthogonal multiple access technology in addition to large capacity transmission abilities. To meet these requirements, we have proposed a chaos non-orthogonal multiple access (C-NOMA) transmission system as a large capacity non-orthogonal multiple access method with physical layer security. This system is secure wireless communication transmission scheme based on the principle of chaos multiple-input multiple-output (C-MIMO) transmission scheme which has both physical layer security and the channel coding gain effect. With this system, secure large capacity communication is possible in the downlink. In this paper, as one study of further improvements of the C-NOMA system, we derive the optimum user capacity calculation formula for improving the transmission performances and compare the result with the conventional method by numerical simulations.
