This paper considers the application of non-orthogonal multiple access (NOMA) into
cooperative cognitive radio (CR) networks with simultaneous wireless information and …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

A novel semantics-empowered two-user uplink non-orthogonal multiple access (NOMA)
framework is proposed for resource efficiency enhancement. More particularly, a secondary …

This article investigates the performance of reconfigurable intelligent surface assisted two-
way non-orthogonal multiple access (RIS-TW-NOMA) networks, where a pair of users …

Non-orthogonal multiple access (NOMA) as an efficient method of radio resource sharing
has its roots in network information theory. For generations of wireless communication …

Internet-of-Things (IoT) technology has received much attention due to its great potential to
interconnect billions of devices in a broad range of applications. IoT networks can provide …

In this letter, the authors consider the non-orthogonal multiple access (NOMA) scheme for
correlated information sources (CIS). We show that in the conventional NOMA scheme, the …

5G mobile communications offer several benefits, which include providing extremely low
latency, very high data rates, significant improvement in the number of users, and increase …

The interplay between the non-orthogonal multiple access (NOMA) and the opportunistic
cognitive radio (CR)-based orthogonal frequency multiple access (OFDMA) has been …

Compared to the traditional orthogonal multiple access (MA), non-orthogonal multiple
access (NOMA) technology can achieve higher capacity gain and higher spectrum …
