Abstract (en)
[origin: WO2014201157A1] In a system having a first communication device with a first plurality of radio-frequency (RF) chains coupled to a first plurality of antennas and a second communication device with a second plurality of RF chains coupled to a second plurality of antennas, the second communication device receives consecutive training packets that were transmitted by the first communication device, the consecutive training packets having been produced at the first communication device by a power level rule to the first plurality of RF chains. The second communication device determines respective channel measurements corresponding to the consecutive training packets based on the power level rule, and selects a transmit parameter based on the respective channel measurements, the transmit parameter to be used by the first communication device when transmitting to the second communication device. The second communication device transmits and indication of the selected transmit parameter to the first communication device.
