Joint User Association and Power Allocation in Heterogeneous NOMA Networks With Imperfect CSI
Non-orthogonal multiple access (NOMA)-enabled heterogeneous networks (N-HetNets) can provide higher system capacity and spectrum efficiency by allowing multiple users cooperating in the same channel. However, traditional resource allocation algorithms are achieved under perfect channel state informa...
