Downlink multi-user non-orthogonal multiple access (NOMA) relay systems, that are wirelessly powered by harvesting energy from radio frequency, are taken into consideration. To enhance the performance of the NOMA multiuser systems, the base station (BS) is equipped with multiple antennas to make a beamforming for transmitting information signal and energy. The close-form outage probability expressions of proposed system over Rayleigh fading channels are derived and the analytical analysis is verified by computer simulations.
