The present disclosure provides for methods and systems for improved channel information gathering mechanism. An aspect of the disclosure provides a method. The method includes sending, to one or more stations (STAs), a request for channel information. The channel information being related to one or more channels between an access point (AP) and the one or more STAs. The method further includes receiving, from the one or more (STA), one or more physical layer (PHY) protocol data units (PPDUs). The PPDUs includes channel feature information (CFI) associated with the one or more channels. In some embodiments, the request includes a beamforming report poll (BFRP) trigger frame having a user information field. The user information subfield indicating one or more thresholds associated with one or more parameters of the channel feature information.
