In this paper, resource allocation for a multi-carrier uplink non-orthogonal multiple access
(NOMA) system is studied. Unlike the existing works on multi-carrier uplink NOMA, in which …

In this work, we propose globally optimal power allocation strategies to maximize the users
sum-rate (SR), and system energy efficiency (EE) in the downlink of single-cell multicarrier …

Non-orthogonal multiple access (NOMA) is a promising technology to increase the spectral
efficiency and enable massive connectivity in 5G and future wireless networks. In contrast to …

This paper investigates the joint subcarrier and power allocation problem for the downlink of
a multi-carrier non-orthogonal multiple access (MC-NOMA) system. A novel three-step …

Due to unrivaled effectiveness, non-orthogonal multiple access (NOMA) has risen as a
promising multiple access scheme for the Internet of things (IoT). In this paper, we provide a …

Non-orthogonal multiple access has attracted much recent attention due to its capability of
improving the system spectral efficiency in wireless communications. Deploying NOMA in a …

With the rapid development of machine-type communications (MTC), the future
communication architecture needs to provide services for both human-type communications …

The future generation of wireless communication networks demands for high spectral
efficiency to accommodate a large number of devices over the limited available frequency …

Non-orthogonal multiple access (NOMA) enables power-domain multiplexing via successive
interference cancellation (SIC) and has been viewed as a promising technology for 5G …

In this paper, we consider a downlink non-orthogonal multiple access (NOMA) enabled
heterogeneous small cells network (HSCN), where the macro base station simultaneously …
