Abstract
A technology that is operable to schedule data transfer for a multiple user multiple-input and multiple-output (MU-MIMO) communications network is disclosed. In one embodiment, an enhanced node B (eNode B) is configured with circuitry configured to receive a sounding signal from each of a plurality of user equipment (UEs). One or more major paths of the sounding signals from each of the plurality of UEs are determined. An angle of arrival (AoA) is determined that is associated with each of the one or more major paths. The plurality of UEs are grouped into one or more candidate MU-MIMO sets using the AoAs associated with each of the one or more major paths. Data transmissions are scheduled for one or more of the candidate UEs of the candidate MU-MIMO set on one or more of the major paths of each of the candidate UEs.
