Abstract
A method and system for controlling application of MU-MIMO. The disclosure provides for considering the quantity of data buffered for transmission over the air between the base station and each of various UEs, and selecting UEs to be subject to MU-MIMO service based on the quantity of data buffered. For example, a base station could prefer application of MU-MIMO for UEs that have more data buffered for transmission than other UEs. Or the base station could condition application of MU-MIMO to a pair of UEs on a determination that each UE of the pair has at least a threshold quantity of data buffered for transmission.
