Abstract

Example implementations are directed to methods and systems employing a solicited sounding protocol that includes an efficient communication sequence for operating a wireless transceiver transmitting a sounding trigger to one or more beamformees via a forward channel, receiving at least one dedicated training signal from the one or more beamformees via a reverse channel in response to the sounding trigger, and for each of the received dedicated training signal. The method also includes estimating forward CSI derived based on the dedicated training signal from an associated beamformee; and where subsequent packets are precoded with precoding derived from the forward CSI for transmission to the associated beamformee via the forward channel. Example aspects including scheduling multiple dedicated training signals from one or more beamformees based on a single sounding trigger.

Claims (4)

1 . A method for operating a wireless transceiver:

determining a sounding control scheme for one or more beamformees;

transmitting a sounding trigger to the one or more beamformees via a forward channel, the sounding trigger conveying aspects of the sounding control scheme; and

receiving at least one dedicated training signal from the one or more beamformees via a reverse channel in response to the sounding trigger and according to the sounding control scheme.
