This paper investigates direct and relay assisted transmission (DRAT) network model with non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIFT). A line of sight is considered between the base station (BS) and a close use, while a dedicated decode-and-forward (DF) relay ensures the communication with a far user with bad channel quality using collected energy. Outage probability is explored in low and high signal to noise ratio (SNR) regime. The impact of power allocation is also shown with simulation results in order to improve system self-sustainability.
