Energy-Efficient D2D Communications Underlaying NOMA-Based Networks With Energy Harvesting - 2018

ABSTRACT:

This letter investigates the resource allocation downside in device-to-device (D2D) communications underlaying a nonorthogonal multiple access based cellular network, where each cellular users (CUs) and D2D users harvest energy from the hybrid access purpose within the downlink and transmit data within the uplink. We propose a low-complexity iterative algorithm to maximise the energy potency of the D2D try whereas guaranteeing the quality of service of CUs. In each iteration, by analyzing the Karush-Kuhn-Tucker conditions, the globally optimal solution can be derived in the closed type despite the nonconvexity. Simulation results validate the superiority of the proposed scheme over the existing schemes.
