In this paper, we study the energy efficiency (EE) maximization problem of a millimeter-wave system with non-orthogonal multiple access. We consider a base station equipped with a single radio frequency chain, which serves two uplink users through analog beamforming. The EE maximization problem is formulated under minimal rate requirements, involves a joint design of power and receive beamformer, and is non-convex in nature. To tackle it, we decompose the original problem into two sub-problems: the power control and beam gain allocation sub-problem, and the beamforming sub-problem. The former is solved via alternating optimization, while the latter is tackled by transforming it into a convex optimization problem. Simulation results show the effectiveness of the proposed algorithms and its superiority over orthogonal multiple access. |
