Abstract: A method and apparatus for beamforming training using frames is provided. A device generates a frame comprising header data and beamforming data. The beamforming data is organized into units of beamforming training (TRN) fields. The header data comprises numbers indicating: a first type of TRN fields in each of the units of the beamforming data, to be transmitted using same antenna settings used for the header data; a second type of TRN fields in each of the units to be transmitted using different antenna settings than used for the header data; and how the first type of TRN fields are organized into respective groups of the second type of TRN fields in each of the units that are to be consecutively transmitted using same respective antenna settings, the respective antenna settings changing with each successive group of the third number of the second type of TRN fields.
