Abstract

Certain aspects of the present disclosure propose transmitting a feedback message to an access point. The feedback may comprise a beamforming extension field, which may carry per tone signal to noise ratio of a station. For certain aspects, the station transmitting the per-tone SNR may be a single user (SU)-capable device. For certain aspects, the station may indicate to the access point whether or not it has a maximum likelihood (ML) receiver.
