WebbA variety of counter-based broadcast schemes have been proposed to mitigate the broadcast-storm problems, using the count threshold value and a random access delay. … Webb14 juni 2024 · Unsourced random access (URA) is a promising technique to implement the massive connection in mMTC proposed recently in (Polyanskiy, 2024). In URA, active users transmit signals to base stations (BSs) or access points randomly, and thus avoid the control signaling overhead resulted by the handshake protocol in the grant-based access.
WebbRandom access schemes dynamically assign radio resources to alarge set of users, each with relatively bursty traffic. A wide variety of solutions have been proposed to solve the problem of how to efficiently allow many terminals to transmit their randomly arriving … WebbThe pioneer of these schemes is contention resolution diversity slotted ALOHA (CRDSA) (concurrently, the work in also proposed a random access tree-resolution scheme that relies on the use of SIC at the receiver, which is able to largely outperform the classic standard and modified tree-algorithms [12,13]) where the nodes are enforced to transmit …

In this paper, we extend this seminal work to the case … Webb20 juli 2024 · In particular, no result is available for modern random access protocols, which have recently emerged as promising solutions to support massive machine-type communications. To start addressing this gap we provide in this paper the first study of the AoI of a scheme in this family, namely irregular repetition slotted ALOHA (IRSA).
