Abstract (in Japanese) (See Japanese page) 
(in English) We propose a non-orthogonal multiple access (NOMA)-based inter-base station (BS) cooperative scheduling method among terminals in multiple service channels to maximized the integrated system throughput. The proposed method optimizes coordinated time/frequency-domain scheduling with inter-BS cooperation and the radio resource allocation using NOMA with successive interference canceller (SIC) from the perspective of integrated system throughput. In the proposed method, the numerical complexity is expected to increase. Therefore, we evaluate the effectiveness of the proposed method narrowing the area of inter-BS cooperation. We also evaluate not only optimal transmission power allocation but also several candidates of simple but sub-optimal transmission power allocation. Computer simulation results reveals that the effectiveness of the proposed method is significant when the system prioritizes the fairness among terminals (including fairness among services). Furthermore, we investigate the level of the performance degradation when we restrict inter-BS cooperation and use the proposed sub-optimal transmission power allocation strategies compared to the case with optimal power allocation.
