Method and apparatus for beamforming training using frames

A method in a wireless communication assembly of a first wireless communication device configured to perform a beamforming refinement procedure with a second wireless communication device, the method comprising:

• generating, at a controller of the first wireless communication device, a frame comprising:
• header data and beamforming data,
• the beamforming data organized into one or more units of beamforming training (TRN) fields,
• the header data comprising:
• a first number (“P”) of a first type of TRN fields in each of the one or more units of the beamforming data, the first type of TRN fields to be transmitted using same antenna settings used for the header data;
• a second number (“M”) of a second type of TRN fields in each of the one or more units of the beamforming data, the second type of TRN fields to be transmitted using different antenna settings than used for the header data;
• and a third number (“N”) of the second type of TRN fields organized into a respective group of the second type of TRN fields in each of the one or more 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 (“N”) of the second type of TRN fields;
• the beamforming data further comprising:
• the one or more units of the TRN fields as defined by the first number, the second number and the third number;
• and the first number of the first type of TRN fields further appended to a last unit;
• and
• transmitting, using a radio of the first wireless communication device, the frame to the second wireless communication device.
