Published in 2022 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2022.3190904

Abstract: Massive machine-type communications protocols have typically been designed under the assumption that coordination between users requires significant communication overhead and is thus impractical. Recent progress in efficient activity detection and collision-free scheduling, however, indicates that… read more here.
