Techniques for beamforming

The present disclosure relates to techniques for beamforming, in particular for WiFi communication schemes such as IEEE 802.11 ax and 802.11 be. In particular the disclosure relates to a beamformer device (110) configured to: transmit a request to a beamformee device (120), the request comprising a set of sounding tone indices, the set of sounding tone indices indicating tones for which a report (121) of beamforming information is requested from the beamformee device (120), 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 (400) defined by the first WiFi scheme for a partial channel bandwidth and on a second tone plan (200) defined by a second WiFi scheme for a full channel bandwidth. The disclosure further relates to a corresponding beamformee device.
