Techniques are provided for improving performance of a multiple-input multiple-output (MIMO) wireless communication system. At a first wireless communication device (e.g., a base station) having a plurality of antennas, uplink transmissions are received from a second wireless communication device (e.g., a client device). The base station determines a measure of multipath conditions between it and the second wireless communication device based on the received uplink transmissions. The base station applies downlink beamforming weight vectors together with power balance and phase adjustment factors depending on the measure of multipath conditions to transmit multiple downlink data streams across the plurality of antennas simultaneously to the second wireless communication device.
