… HetNet subjected to the constraints of the user QoS demand and total transmit power of BSs,
we formulate a power allocation problem which proves to be an NP-hard problem. To deal …

… users over the same transmission resources, ie, time… -NOMA models for downlink
power allocation in multi-cell networks, we focus on a joint transmission CoMP-NOMA (JT-CoMP-NOMA…

… application of NOMA, in this work, we study the joint beamforming and power allocation
design where users have similar channel gains to further unlock the potential benefit of NOMA. …

… However, the existing PA schemes for MC-NOMA suffer from very high complexity and are
… PA for MC-NOMA systems. We consider the downlink transmission for two user receivers, …
