Abstract
Systems and methods are provided for dynamically modifying beamforming weights based on MU-MIMO user device pairings. A quantity of MU-MIMO user device pairings served by a node is determined. Based on a maximum quantity of potential MU-MIMO user device pairings for the node, it is determined that a quantity of the MU-MIMO user device pairings for the node is below a threshold. Because the quantity of the MU-MIMO user device pairings is below the threshold, beamforming weights are modified to widen a vertical main lobe to increase the quantity of MU-MIMO user device pairings.
