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.
