N2 - This paper considers resource allocation for network-coded clustered uplink non-orthogonal multiple-access (NOMA) networks with simultaneous wireless information and power transfer (SWIPT)-enabled relays. In particular, the goal is to perform joint power allocation, power-splitting, and relay selection (J-PA-PS-RS) to maximize the network sum-rate, subject to quality-of-service requirements. The formulated problem happens to be a non-convex and excessively complex. Thus, it is split into two sub-problems: (1) joint power allocation and power-splitting per relay, and (2) relay selection. Particularly, a solution procedure is proposed, where the joint user and relay power allocation, and power-splitting per relay is solved via a low-complexity iterative three-layer algorithm, and then followed by optimal relay selection. Simulation results have revealed that the proposed solution procedure achieves near-optimal solutions as well as being superior to the OMA-based network.
