Abstract:
1. A method comprising: at a base station, receiving uplink transmissions at a plurality of antennas from a plurality of client stations; analyzing the uplink transmissions to obtain a plurality of direction of arrival (DOA) components for each of the plurality of client stations; determining a plurality of strongest DOA components for each of the plurality of client stations, wherein the plurality of strongest DOA components are a subset of the DOA components, wherein each of the strongest DOA components are associated with one of a plurality of segments, and wherein each segment is a degree range corresponding to DOA; and selecting two or more client stations from the plurality of client stations to participate in an uplink collaborative spatial multiplexing transmission session, wherein the two or more client stations collaborate in an uplink session to send uplink transmissions on substantially the same frequency channel at substantially the same time, even though the uplink transmissions substantially interfere, wherein the selecting is based on dissimilarities of the plurality of strongest DOA components of the two or more client stations.
