Fifth generation (5G) mobile communication systems have entered the stage of commercial
deployment, providing users with new services, improved user experiences as well as a host …

Over the last few years, interference has been a major hurdle for successfully implementing
various end-user applications in the fifth-generation (5G) of wireless networks. During this …

This paper investigates the secure transmission in a simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS) assisted uplink non-orthogonal …

We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

This article studies the reliable and secure communications for a wireless-powered non-
orthogonal multiple access (NOMA) system in the presence of multiple eavesdroppers. A …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

Nonorthogonal multiple access (NOMA) assisted semi-grant-free transmission admits grant-
free users to access the channels otherwise solely occupied by grant-based users, and has …

In this paper, we investigate unmanned aerial vehicle (UAV) assisted physical layer security
in multi-beam satellite enabled vehicle communications. Particularly, the UAV is exploited as …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

With 5G mobile communication systems having been commercially rolled out, research
discussions on next generation mobile systems, that is, 6G, have started. On the other hand …
