Optimization of CF-mMIMO Systems for the Coexistence between eMBB+ and mMTC+: From Analytical to GNN-Aided Designs
Sergi Liesegang, Lou Salaün, Chung Shue Chen +1
This paper investigates uplink multiple access for the coexistence of enhanced mobile broadband+ (eMBB+) and massive machine-type communications+ (mMTC+) in terminal-centric cell-f…
Graph-Neural Multi-Agent Coordination for Distributed Access-Point Selection in Cell-Free Massive MIMO
Mohammad Zangooei, Lou Salaün, Chung Shue Chen +1
Cell-free massive MIMO (CFmMIMO) systems require scalable and reliable distributed coordination mechanisms to operate under stringent communication and latency constraints. A centr…
Unsupervised Graph-based Learning Method for Sub-band Allocation in 6G Subnetworks
Daniel Abode, Ramoni Adeogun, Lou Salaün +3
In this paper, we present an unsupervised approach for frequency sub-band allocation in wireless networks using graph-based learning. We consider a dense deployment of subnetworks…
Learning Optimal Linear Precoding for Cell-Free Massive MIMO with GNN
Benjamin Parlier, Lou Salaün, Hong Yang
We develop a graph neural network (GNN) to compute, within a time budget of 1 to 2 milliseconds required by practical systems, the optimal linear precoder (OLP) maximizing the mini…
