Resource Allocation for Energy Efficiency in NOMA Enhanced Small Cell Networks

In this paper, we consider a downlink non-orthogonal multiple access (NOMA) heterogeneous small cell networks (HSCN), where the macro base station (MBS) simultaneously communicate with multiple small cell base stations (SBS) through the wireless backhauls. The goal is to investigate an energy-efficient power, and bandwidth allocation scheme aiming at maximizing the EE of the small cells in downlink NOMA-HSCN constrained by the maximum transmit...
