In this article, we consider the massive nonorthogonal multiple access (NOMA) with a hybrid
automatic repeat request (HARQ) for short packet communications. To reduce the latency …

This letter proposes a priority access (PA) in non-orthogonal multiple access (NOMA)-based
slotted ALOHA (SA)(PA-NOMA-SA) for overload 6G massive Internet of Things (IoT). First, a …

Machine-to-machine (M2M) constitutes the communication paradigm at the basis of Internet
of Things vision. M2M solutions allow billions of multi-role devices to communicate with each …

Non-orthogonal multiple access (NOMA) is expected as a promising technology for
satisfying massive connectivity requirements in Internet of Things (IoT). Besides, short …

Nonorthogonal multiple access (NOMA) is classified into grant-based (GB) random access
(RA) and grant-free (GF) RA in 5G systems. GF NOMA RA allows user equipments (UE) to …

Being able to accommodate multiple simultaneous transmissions on a single channel, non-
orthogonal multiple access (NOMA) appears as an attractive solution to support massive …

Internet of Things (IoT) networks require massive connections in dense areas. Therefore, a
resource-efficient multiple access scheme seems inevitable to enable immense connectivity …

Non-Orthogonal Multiple-Access (NOMA) where multiple users share the same resources
simultaneously, is one promising candidate for beyond 5G. Besides, an Ultra-Dense …

Irregular repetition slotted ALOHA (IRSA) based non-orthogonal multiple access (NOMA)
with priority adaptive traffic load (ATL)(PATL-IRSA-NOMA) is proposed to prioritize the …

This article investigates the performance of nonorthogonal multiple access (NOMA)-based
cell-free massive multiple-input–multiple-output (mMIMO) for the Internet of Things (IoT) …
