Massive mimo unsourced random access

Web7 de feb. de 2024 · We put forward a new algorithmic solution to the massive unsourced random access (URA) problem, by leveraging the rich spatial dimensionality offered by large-scale antenna arrays. This paper makes an observation that spatial signature is key to URA in massive connectivity setups. WebUnified: Analysis of different random-access schemes can all be based on the same framework. Scalable: Modeling complexity does not increase with the network size. Keys to establishing a unified and scalable analytical framework for random-access networks [Dai’12] [Dai’13]: — Treat each node’s queue as an independent queueing system;
