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…
Design and Performance of Enhanced Spread Spectrum Aloha for Unsourced Multiple Access
Riccardo Schiavone, Gianluigi Liva, Roberto Garello
We analyze the performance of enhanced spread spectrum Aloha (E-SSA) in the framework of unsourced multiple access (UMAC). The asynchronous, unframed transmission of E-SSA is modif…
