In this article, we investigate the integration of NOMA into cooperative relaying. We first
introduce several fundamental cooperative NOMA network structures, and then classify them …

Full-duplex (FD) communication is a potential game changer for future wireless networks. It
allows for simultaneous transmit and receive operations over the same frequency band, a …

In a downlink non-orthogonal multiple access (NOMA) system, the reliable transmission of
cell-edge users cannot be guaranteed due to severe channel fading. On the other hand, the …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

Although the use of coordinated direct and relay transmission (CDRT) in non-orthogonal
multiple access (NOMA) can extend the coverage, its duplicated transmission reduces the …

In this paper, a backscatter cooperation (BC) scheme is proposed for non-orthogonal
multiple access (NOMA) downlink transmission. The key idea is to backscatter the surplus …

The impact of imperfect channel state (CSI) information in an energy harvesting (EH)
cooperative non-orthogonal multiple access (NOMA) network, consisting of a source, two …

With the continuous development of B5G/6G cellular networks, the explosive growth of
mobile Internet services and the resulting tremendous traffic demand have led to a …

In this article, we study the physical-layer security (PHY-security) improvement method for a
downlink nonorthogonal multiple access (NOMA) system in the presence of an active …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …
