Abstract (in Japanese) (See Japanese page) 
(in English) We propose a novel non-orthogonal multiple access (NOMA)-based optimal multiplexing method of multiple downlink service channels to maximize the integrated system throughput. In the fifth generation (5G) mobile communication system, the support of various wireless communication services such as massive machine-type communications (mMTC) and ultra-reliable low latency communications (URLLC) in addition to enhanced mobile broadband (eMBB) is expected. These services will serve different numbers of terminals and have different requirements regarding the spectrum efficiency and fairness among terminals. Furthermore, different operators may have different policies regarding the overall spectrum efficiency and fairness among services. Therefore, an efficient radio resource allocation during the multiplexing of multiple downlink service channels considering these requirements is essential. The proposed method achieves better system performance than the conventional orthogonal multiple access (OMA)-based multiplexing method thanks to the wider transmission bandwidth per terminal and inter-terminal interference cancellation by using the successive interference canceller (SIC). Computer simulation results reveals that the effectiveness of the proposed method especially significant when the system prioritizes the fairness among terminals (including fairness among services).
