In this paper, we study two transmission scenarios for the base station (BS) in cellular
networks to serve the far user, who is located at the cell-edge area in such a network. In …

In this article, we investigate two-tier nonorthogonal multiple access (NOMA)-based wireless
powered communication networks. The considered network consists of a hybrid access …

This paper investigates a novel communication paradigm employing movable antennas
(MAs) within a multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) …

This paper proposes a peer-assisted power supply approach for a wireless powered Internet
of Things (IoT) non-orthogonal multiple access (NOMA) network in which passive user …

In a conventional Cooperative Non Orthogonal Multiple Access (NOMA) scheme, only one
user from the NOMA pair acts as a relay and forwards information to the other user. In this …

In this paper, we study the performance of a cell-edge user in a two-user multiple-input
single-output nonorthogonal multiple access (MISO-NOMA) system. Since the outage …

Spectrum scarcity is one of the most important challenges in wireless communications
networks due to the sky-rocketing growth of multimedia applications. As the latest member of …

While non-orthogonal multiple access (NOMA) improves spectral efficiency, it adds
complexity to the receivers due to successive interference cancellation (SIC). Prior studies …

Towards energy savings in large-scale nonorthogonal multiple access (NOMA) networks,
we investigate power and load optimization for multi-cell and multi-carrier NOMA systems in …

This paper investigates the user clustering and power control in the uplink multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) networks. A joint optimization …
