Certain aspects of the present disclosure provide methods and apparatus for enhancing a beamforming training procedure. For example, an apparatus can include a processing system that generates a plurality of transmit beamforming refinement frames for a transmit sector sweep that each include a preamble, a data field, at least one beamforming training field, identification of a transmit antenna array to be used for transmitting the at least one beamforming training field, and a status indication of whether the transmit beamforming refinement frame is a last transmit beamforming refinement frame in the transmit sector sweep for one or more receive antenna arrays of a wireless node. The apparatus also includes a first interface that outputs the transmit beamforming refinement frames using a first transmit beamforming sector for the preambles and data fields, and one or more second transmit beamforming sectors for subfields of the beamforming training fields.
