focus on energy-efficient wireless communications for downlink NOMA HetNets via resource …

… Afterwards we analyze how to optimally allocate the powers among the K NOMA users for
the non-coordinated NOMA and coordinated JT-NOMA schemes in order to maximize the cell …

… Instead, to make full use of the advantage of NOMA technique, as shown in Fig.1, we develop
a NOMA heterogeneous network, where the NOMA protocol is applied to both macrocells …
