Tensor-based Random Access for Ambient IoT Contention Resolution
Alberto Rech, Alexis Decurninge, Ala Baccar, Sofiane Kharbech
Ambient Internet of Things (A-IoT) deployments impose stringent hardware constraints, including low-order modulations and simple transceiver architectures. We propose a tensor-based grant-free random access scheme for the initial access message (Msg1) tailored to these limitation…
