… Abstract—In this paper, energy-efficient power allocation (PA) is investigated for a
multiple-input multiple-output nonorthogonal multiple access (MIMO-NOMA) system with multiple …

… energy efficient power allocation is considered for a multiuser uplink non-orthogonal
multiple access (NOMA… Due to the QoS requirements, the considered energy-efficiency (EE) …

… works on NOMA networks, in this article, we focus on energy-efficient wireless communications
for downlink NOMA … More specifically, we study user scheduling and power allocation by …

… The derived accurate results show that coordinated JT-NOMA … power allocation schemes
that maximize the average cell coverage and throughput under some derived power allocation …

… In the most prior power allocation schemes, the perfect channel state information (… a power
allocation scheme to maximize energy efficiency for downlink NOMA heterogeneous networks …

… improves the spectral efficiency whereas results in a … NOMA HetNet, meanwhile ensure the
desired quality of service (QoS) of each user, we mathematically formulate a power allocation …

… (NOMA). Multiple two-user clusters are formed according to their channel correlation and
gain difference, and NOMA is … On this basis, we formulate a power allocation (PA) problem to …

… On the other hand, non-orthogonal multiple access (NOMA) is a promising technique … power
allocation (PA) are jointly optimized to improve the performance of the NOMA-UAV network. …

… However, the energy efficiency (EE) optimization problem in NOMA … network (HetNet) with
