Abstract:
1. A method of processing data in a multiple-input multiple-output (MIMO) communication system, comprising: generating, at an apparatus, an uplink channel response matrix for each of a plurality of transmitting entities; deriving a steering vector for each of the transmitting entities by decomposing the channel response matrix to obtain a plurality of eigenvectors and a plurality of singular values, and forming the steering vector for each transmitting entity based on an eigenvector corresponding to a largest singular value among the plurality of singular values; evaluating different sets of the transmitting entities and selecting a best set for transmission and reception; sending, to each transmitting entity in the selected best set, a rate selected based on the steering vector and the channel response matrix; and sending the steering vector to each transmitting entity in the selected best set for use in spatially processing data symbol streams to be transmitted to the apparatus from a plurality of transmit antennas at the transmitting entity.
