Joint Beamforming and Integer User Association using a GNN with Gumbel-Softmax Reparameterizations
A GNN trained with Gumbel-Softmax and straight-through estimation outputs guaranteed-integer user associations and achieves higher simulated sum-rate than fractional-association baselines in mmWave multi-cell networks.
