The Satellite Internet of Things (IoT) has become an important part of global interconnection,
and its wide-area coverage is bound to generate massive access. According to the …

The sixth-generation (6G) has defined ultra-massive machine type communication (umMTC)
as a key scenario to address advances in Internet of Things technologies. However, the …

Simplified packet reception models such as collision model are usually adopted for
optimizing irregular repetition slotted ALOHA (IRSA), which may lead to performance penalty …

Due to the large number of terminals in machine-type communications, random access
(grant-free) communications show more advantages than granted communications in …

In this letter, a novel power diversity-based priority (PDP) scheme is introduced in
nonorthogonal multiple access with irregular repetition slotted ALOHA (IRSA-NOMA) …

Ultra-massive machine-type communications (umMTC) is the key point of 6G to support
massive internet-of-things (IoT). To support these requirements, this paper proposes a novel …
