Abstract:
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.

Claim (Index 11):
An apparatus for wireless communications, comprising:\n a first interface configured to obtain a plurality of transmit beamforming refinement frames during a sector sweep, wherein:\n each transmit beamforming refinement frame has:\n a training field, \n an identification of a transmit antenna array used by a wireless node for transmitting the training field, and \n a status indication of whether the transmit beamforming refinement frame is a last transmit beamforming refinement frame in the sector sweep for one or more receive antenna arrays, and \n \n a processing system configured to:\n determine the sector sweep for at least one of the receive antenna arrays is over based on the status indication contained therein and, \n in response to the determination,\n select one or more first transmit beamforming sectors that were used to transmit one or more training fields of the transmit beamforming refinement frames, based on received signal quality of the one or more training fields, and \n generate a feedback frame identifying one or more one of the selected first transmit beamforming sectors and, for each of the selected first transmit beamforming sectors, one of the identified transmit antenna arrays of the wireless node and one of the one or more receive antenna arrays; and \n \n a second interface configured to output the feedback frame for transmission.
