Massive machine-type communications (mMTC) is one of the main three focus areas in the
5th generation (5G) of wireless communications technologies to enable connectivity of a …

Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth-
generation (5G) wireless networks to meet the heterogeneous demands on low latency, high …

Driven by the rapid escalation of the wireless capacity requirements imposed by advanced
multimedia applications (eg, ultrahigh-definition video, virtual reality, etc.), as well as the …

Intelligent reflecting surfaces (IRSs) are envisioned to provide reconfigurable wireless
environments for future communication networks. In this paper, both downlink and uplink …

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 …

Today's wireless networks allocate radio resources to users based on the orthogonal
multiple access (OMA) principle. However, as the number of users increases, OMA based …

Non‐orthogonal multiple access (NOMA) is a strong candidate for next generation radio
access networks due to its ability of serving multiple users using the same time and …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

We study a downlink non-orthogonal multiple access system with cooperative full-duplex
relaying, where the near user in terms of the base station (BS) is enabled to act as a full …

Intelligent reflecting surface (IRS) is a promising technology to enhance the coverage and
performance of wireless networks. We consider the application of IRS to non-orthogonal …
