Non-orthogonal multiple access (NOMA)-enabled heterogeneous networks (N-HetNets)
can provide higher system capacity and spectrum efficiency by allowing multiple users …

… Specifically, we provide both the uplink and downlink cases for the unified NOMA enabled
HUDNs. We discuss user association and resource allocation in NOMA enabled HUDNs. We …

… , we propose a joint user-RB association and PA algorithm, which is guaranteed to converge.
Moreover, regarding the power allocation under a given userRB association, we first derive …

… In such a scenario, NOMA based on the successive interference cancellation … of jointly
optimizing user association (UA) and power control to maximize the overall SE, subject to user-…

… interference among users in uplink NOMA. Then, we obtain a game model for the joint user
association, grouping and power allocation (JAGP) problem in uplink NOMA systems and …

… of stable user association and channel assignment in downlink multi-cell non-orthogonal
multiple-access (NOMA) networks. To be specific, the goal is to assign network users to the …

… of joint power allocation and user association is studied for non-orthogonal multiple access
(NOMA) downlink networks … the joint power control and user association for downlink NOMA …

… In this context, the application of Non-Orthogonal Multiple Access (NOMA) … joint user
association and uplink power allocation, in heterogeneous 5G wireless networks, employing NOMA …

… -cell networks. This paper investigated the joint optimization problem of user association and
… -cell non-orthogonal multiple access (NOMA) networks. The problem is decomposed into …

… NOMA networks, and we formulate the joint user association and power allocation problem
for the downlink multicell NOMA networks … problem, we decouple user association and power …
