Abstract (in Japanese) (See Japanese page) 
(in English) Taking into account imperfect channel state information, we study a robust transmit beamforming design for downlink power domain non-orthogonal multiple access (PD-NOMA) schemes. A beamforming-based multiple-input single-output (MISO) downlink NOMA scenario is particularly considered in this paper, in which one base-station simultaneously serves for single-antenna downlink users in a non-orthogonal manner, proposing a new algorithm to design transmit beamforming vectors minimizing the total transmit power consumption while maintaining prescribed quality of service (QoS) requirements. Simulation results illustrate the effectiveness of the proposed algorithm, which is found to outperform non-robust counterparts taking no account of such CSI imperfection in terms of the total transmit power consumption and SINR outage probability.
