Abstract
The antenna configurations of a wireless communications system including a beamformer and beamformee may be changed. In an improved technique for triggering a sounding packet, notification of an antenna re-configuration, either at the beamformer or the beamformee can be quickly used by the beamformer to trigger the sounding packet. In one embodiment, the beamformee can perform its own computations to determine a changing channel. In this embodiment, once a changing channel is detected, the beamformee can notify the beamformer to trigger the sounding packet.
