Claim:
1. A method, comprising: transmitting, with a first communication device, a first sounding packet modulated using orthogonal frequency division multiplexing (OFDM), wherein the first sounding packet is in connection with beamforming training for a multiuser (MU) transmission; receiving, at the first communication device, a first feedback packet that was transmitted by a second communication device, the first feedback packet including a first feedback report corresponding to the first sounding packet, the first feedback report including using, at the first communication device, information from the first feedback report to beamform the MU transmission; transmitting, from the first communication device, a second sounding packet modulated using OFDM, the second sounding packet corresponding to beamforming training for a single user (SU) transmission; receiving, at the first communication device, a second feedback packet that was transmitted by the second communication device, the second feedback packet including a second feedback report corresponding to the second sounding packet, the second feedback report including: wherein the second feedback packet does not include any deltas corresponding to PT-SNRs associated with the second sounding packet; and using, at the first communication device, information from the second feedback report to beamform the SU transmission.
