Abstract: A system and method for downlink feedback in communications between a station and an access point. In some embodiments, the method includes: receiving, from the access point, by the station, a null data packet announcement (NDPA) including a first number of spatial streams, and sending, by the station, to the access point, a Compressed Beamforming Report (CBR) including a second number of spatial streams, different from the first number of spatial streams; or sending, by the station, to the access point, an Operating Mode Indication (OMI) declaring a change in a station Modulation Coding Scheme (MCS) capability for a third number of spatial streams; or sending, by the station, to the access point, an Association Request including a declared Single-User (SU) MCS capability for a first bandwidth and a declared Multi-User (MU) MCS capability for the first bandwidth, the MU MCS capability being different from the SU MCS capability.

Abstract: A method according to some embodiments include reporting, by a beamformee, an encryption capability indicator to a beamformer, wherein the encryption capability indicator is indicative of a capability of the beamformee to encrypt a feedback frame. The method may also include receiving, by the beamformee from the beamformer, an announcement frame in response to the beamformer receiving an indication that the beamformee is capable of encrypting the feedback frame, and then sending, by the beamformee, an encrypted feedback frame.
