To Share, or Not to Share: A Study on GEO-LEO Systems for IoT Services with Random Access
Marcel Grec, Federico Clazzer, Israel Leyva-Mayorga +3
The increasing number of satellite deployments, both in the low and geostationary Earth orbit exacerbates the already ongoing scarcity of wireless resources when targeting ubiquito…
A low-PAPR Pilot Design and Optimization for OTFS Modulation
Davide Bergamasco, Federico Clazzer, Andrea Munari +1
Orthogonal time frequency space (OTFS) modulation has been proposed recently as a new waveform in the context of doubly-selective multi-path channels. This article proposes a novel…
Evolution of the 5G New Radio Two-Step Random Access towards 6G Unsourced MAC
Patrick Agostini, Jean-Francois Chamberland, Federico Clazzer +7
This report summarizes some considerations on possible evolutions of grant-free random access in the next generation of the 3GPP wireless cellular standard. The analysis is carried…
An Investigation of the Compressed Sensing Phase in Unsourced Multiple Access
Federico Clazzer, Farouk Amri, Marcel Grec
A vast population of low-cost low-power transmitters sporadically sending small amounts of data over a common wireless medium is one of the main scenarios for Internet of things (I…
Two-Tier Multi-Rate Slotted ALOHA for OWC/RF-Based IoT Networks
Milica Petkovic, Dejan Vukobratovic, Andrea Munari +1
We consider a massive Internet of Things (IoT) scenario where indoor IoT devices access the network via optical wireless communication (OWC) IoT systems that relay data via a backh…
Relay-aided Slotted Aloha for Optical Wireless Communications
Milica Petkovic, Dejan Vukobratović, Andrea Munari +1
We consider a relay-aided Slotted ALOHA solution for uplink random access for an Optical Wireless Communications (OWC)-based Internet of Things (IoT). The first phase of uplink, th…
