Claim Text:
1. A method for operating a base station in a wireless network including the base station and a plurality of user equipments, wherein the base station includes a plurality of antennas, wherein each of the user equipments includes one antenna, the method comprising: a) for each of the user equipments, determining a steering vector for the user equipment based on a transmission from the user equipment to the base station; b) for each of the user equipments, comparing the steering vector for the user equipment with the steering vector for another one of the user equipments, to determine a corresponding orthogonality factor for the steering vectors; c) selecting for simultaneous transmission a first pair of the user equipments whose corresponding orthogonality factor is below a first threshold and whose combined throughput is greater than a second threshold, wherein said simultaneous transmission is co-scheduled transmission on a same time-frequency resource block; d) separately scheduling a second pair of the user equipments whose corresponding orthogonality factor is greater than the first threshold.
