Method and apparatus of multi-user selection for multi-user mimo

Abstract

A wireless communication device for facilitating wireless communication is provided. The device transmits a training frame, and receives a plurality of feedback frames including channel quality information from a plurality of stations in response to the training frame. The device determines a plurality of groups based on the channel quality information in the plurality of feedback frames. Each of the plurality of groups is associated with a respective one of the plurality of stations and includes an associated station as a primary station and at least one secondary station. The device determines channel capacities of the plurality of groups and selects a group of the plurality of groups based on the channel capacities of the plurality of groups. The device determines users of the selected group as MU-MIMO users and transmits a MU PPDU in MU-MIMO for the users of the selected group.
