Space Diversity-Based Grant-Free Random Access for Critical and Non-Critical IoT Services
Rahif Kassab, Osvaldo Simeone, Andrea Munari +1
In this paper, we study the coexistence of critical and non-critical Internet of Things (IoT) services on a grant-free channel consisting of radio access and backhaul segments. On…
Protograph LDPC Code Design for Asynchronous Random Access
Federico Clazzer, Balazs Matuz, Sachini Jayasooriya +2
This work addresses the physical layer channel code design for an uncoordinated, frame- and slot-asynchronous random access protocol. Starting from the observation that collisions…
Modern Random Access for Beyond-5G Systems: a Multiple-Relay ALOHA Perspective
Andrea Munari, Federico Clazzer
Modern random access protocols are emerging as an efficient yet simple solution for arising internet of things (IoT) applications in upcoming beyond-5G systems. In this context, bo…
Multiple-Relay Slotted ALOHA: Performance Analysis and Bounds
Andrea Munari, Federico Clazzer, Gianluigi Liva +1
Wireless random access protocols are attracting a revived research interest as a simple yet effective solution for machine-type communications. In the quest to improve reliability…
From 5G to 6G: Has the Time for Modern Random Access Come?
Federico Clazzer, Andrea Munari, Gianluigi Liva +3
This short paper proposes the use of modern random access for IoT applications in 6G. A short overview of recent advances in uncoordinated medium access is provided, highlighting t…
