Claim Text:
1. A method of beamforming within a communication system having (i) a first transceiver device having a first plurality of antennas and (ii) a second transceiver device having a second plurality of antennas, the method comprising: transmitting, from the first transceiver device to the second transceiver device, via a forward channel a first calibration signal requesting a non-sounding packet from the second transceiver device, where the non-sounding packet from the second transceiver device is to include a description of the forward channel; receiving, at the first transceiver device, via a reverse channel the non-sounding packet from the second transceiver device; receiving, at the first transceiver device from the second transceiver device, via the reverse channel a second calibration signal requesting a non-sounding packet from the first transceiver device, where the non-sounding packet from the first transceiver device is to include a description of the reverse channel; determining, at the first transceiver device, (i) a partial dimensional description of the reverse channel based on receipt of the non-sounding packet from the second transceiver device or (ii) a full dimensional description of the reverse channel based on receipt of the second calibration signal requesting the non-sounding packet from the first transceiver device; and determining, at the first transceiver device, a first device correction matrix from the received non-sounding packet from the second transceiver device and (i) the partial dimensional description of the reverse channel or (ii) full dimensional description of the reverse channel, wherein the first transceiver is to use the correction matrix to process signals to be transmitted via the forward channel, where the first device correction matrix is for use in transmitting data via the forward channel.
