Non-Orthogonal Multiple Access in Massive MIMO Aided Heterogeneous Networks

, 2016
In this paper, the application of non-orthogonal multiple access (NOMA) into K-tier heterogeneous networks (HetNets) is investigated. A new promising transmission framework is proposed, in which massive multiple-input multiple-output (MIMO) is employed ...

Non-orthogonal multiple access (NOMA) for cellular wireless communications

, 2017
This thesis begins with an overview of the basic concept of NOMA by identifying the key working principle of NOMA systems and their respective power allocation requirements in both of downlink and uplink transmissions. Then, for cell-throughput maximization in both of downlink and uplink NOMA transmissions, the joint problem of user clustering and ...
