Abstract
A beamformer device is provided for WiFi communication schemes such as IEEE 802.11ax and 802.11be. The beamformer device is configured 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 defined by the first WiFi scheme for a partial channel bandwidth and on a second tone plan defined by a second WiFi scheme for a full channel bandwidth. A corresponding beamformee device is further provided.
