Abstract
Example embodiments are directed toward a system and a method for downlink scheduling in a multi-user, multiple-input and multiple-output (MU-MIMO) network with a central controller employing a scheduling scheme pre-selecting user equipment according to probabilities obtained from a large-system analysis. Only pre-selected user equipment is requested to feedback channel state information, thereby reducing cluster interference and increasing throughput while greatly reducing the required feedback channel state information generally required to schedule transmissions.
