QoS Based Energy Efficiency Maximization for Uplink NOMA Networks

Non orthogonal multiple access (NOMA) grasped remarkable interest in fifth generation (5G) owing to its remarkable spectral efficiency. Less resource availability motivates researchers to find an efficient way to distribute it amongst users. While taking into account of power budget and minimum user rate (QoS) constraint, the system energy efficiency (EE) optimization problem is formulated to balance the system throughput and total power consumption. Our aim is to optimize channel assignment with power allocation for the maximization of the EE in uplink NOMA system. Energy efficient resource distribution technique with a lower degree of complexity is discussed. System EE is an output metric that is addressed, evaluated, and considered for the simulation outcomes.
