1. A beamformer device comprises:
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions to cause the beamformer device to:
transmit a request to a beamformee device, the request comprising a set of sounding tone indices, the set of sounding tone indices indicating tones for which a report of beamforming information is requested from the beamformee device,
wherein the tones are defined according to a first WiFi scheme,
wherein the set of sounding tone indices is based on a first tone plan and a second tone plan,
wherein the first tone plan is defined by the first WiFi scheme for a partial channel bandwidth, and the second tone plan is defined by a second WiFi scheme for a full channel bandwidth, and
wherein the sounding tone indices are based on a new sounding index set for the partial channel bandwidth and additional center tones indices for the full channel bandwidth.
