Reconfigurable intelligent surfaces (RIS) emerges as a novel communication technology for
the 6G networks, boasting advantages such as low cost, high energy efficiency, and wide …

Although the non-orthogonal multiple access network (NOMA) network has already been
used in 5G in wireless communication, it still needs to be supplied with large enough …

This paper investigates the outage performance of the communications between two pairs of
source-destination in a non-orthogonal multiple access (NOMA) system where a multi …

The outdated relay selection algorithm for UAV-enabled cooperative amplify-and-forward
NOMA networks is investigated in this paper. The impacts of the system parameters such as …

In recent years, there has been a continuous increase in the requirement for consistent
connectivity, high-speed data rates, and high quality of service (QoS) for mobile …

To harness the benefits of non-orthogonal multiple access (NOMA) and reconfigurable
intelligent surfaces (RISs), we propose a novel RIS-empowered decode-and-forward (RIS …

In this paper, we investigate a downlink cooperative non-orthogonal multiple access
(NOMA) network with decode-and-forward relaying, where two scenarios of user relaying …

This paper examines the performance of a wireless system where two reconfigurable
intelligent surfaces (RISs) and an unmanned aerial vehicle (UAV) are combined to aid …

Recently, non-orthogonal multiple access (NOMA) scheme is integrated with cooperative
communication (C-NOMA) to increase the connectivity and coverage area. In this paper, we …

In this paper, we investigate the performance of reconfigurable intelligent surface (RIS)-
assisted aerial communications, where a ground base station (GBS) communicates with …
