  Abstract: In this work, we study a non-orthogonal multiple access scheme used for the uplink of a wireless-powered communication system. We focus on data rates optimization and fairness increase. We show that the formulated optimization problems can be optimally and efficiently solved by either linear programming methods or convex optimization, which means that the proposed scheme can be easily implemented in practical applications. Simulation results illustrate that the proposed scheme outperforms the baseline orthogonal scheme, while they reveal the dependence between sum-throughput, minimum data rate, and wireless power transfer.
