In this paper, we investigate energy efficiency (EE) maximization in multicell multicarrier non-
orthogonal multiple access (MCMC-NOMA) networks with hardware impairments (HIs). We …

In this paper, we tackle the problem of optimizing user clustering, power, and resource (time
slot or bandwidth) allocation in the downlink of a hybrid non-orthogonal multiple access …

Spectral efficiency is crucial for implementing 5G cellular networks and beyond. Non-
orthogonal multiple access (NOMA) is a promising scheme to enhance efficiency. This paper …

The motivations for deploying energy and spectral-efficient network architectures are the
high energy consumption and the need for more spectral resources in modern cellular …

In this paper, we investigate joint subcarrier and power allocation in multicarrier
nonorthogonal multiple access (MC‐NOMA) systems aims to guarantee rate proportional …

The explosive growth of data leads to that the traditional wireless networks cannot enable
various quality of service (QoS) communication for cellular‐connected multi‐UAV …

While UAV ad hoc networks have made significant progress, implementing it in most of real-
application scenarios is challenging due to data explosion. Instead of only ad hoc mode, this …

With the rapid development of Internet and IoT, the demand for system capacity and
spectrum efficiency is increasing, and Non-Orthogonal Multiple Access (NOMA) is being …

In this paper, uplink secure transmission in a non-orthogonal multiple access (NOMA)
network is investigated by selection of the users for data transmission to the base station …
