Abstract: A multi-user multiple-input multiple-output (MU-MIMO) scheduling method is disclosed for scheduling transmission from a plurality of transmission instances to a plurality of receivers. The method comprises acquiring, for each pair of a transmission instance and a receiver, a communication quality metric and forming a first group of receivers from the plurality of receivers. The first group of receivers is formed by selecting a first receiver as a first group member and associating a first transmission instance to the first receiver and—when a plurality of communication quality metrics of the first transmission instance and not yet selected receivers fulfill a first criterion for sufficient communication quality—selecting a second receiver from the not yet selected receivers as a second group member and associating a second transmission instance to the second receiver.
