The upcoming satellite-based Internet of Things (S-IoT) has the capability to provide timely
status updates to massive terrestrial user equipments (UEs) via non-orthogonal multiple …

Short packet communications are widely used for sixth generation (6G) mission-critical
applications, which also bring challenges such as the transmission error caused by …

In this paper, we propose bi-directional cooperative non-orthogonal multiple access
(NOMA). Compared to conventional NOMA, the main contributions of bi-directional …

Age of Information (AoI) is a critical performance metric for measuring information freshness
in task-oriented Internet of Things (IoT) applications. In this work, we investigate how AoI …

This letter investigates the benefits of integrating reconfigurable intelligent surface (RIS) on
minimizing the average sum age of information in uplink NOMA-based IoT networks. A …

We investigate the age of information (AoI) of relay-assisted cooperative communication
systems. For time-slotted systems without relaying, prior works have shown that the source …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising
multiple access scheme for realizing next generation wireless communications. Unlike …

The paradigm of the upcoming 5G and beyond is the machine type communications (MTC),
where a large number of devices automatically operate wireless communications. Due to …

In this paper, we examine the potentials of Non-Orthogonal Multiple Access (NOMA),
currently rivaling Orthogonal Multiple Access (OMA) in 3rd Generation Partnership Project …

This paper investigates the benefits of integrating multiple reconfigurable intelligent surfaces
(RISs) in enhancing the timeliness performance of uplink Internet-of-Things (IoT) network …
