Claim of US Patent No. 9,219,576

1. A method for generating a beamforming training (BFT) unit, the method comprising:
generating a physical layer (PHY) preamble of the BFT unit; and
generating a first encoding block and a second encoding block using PHY data and media access control layer (MAC) data, including
at least one of:

i) using a number of padding bits in a PHY layer of the BFT unit such that the PHY data and the MAC data are encoded into
only the first encoding block and the second encoding block, and/or

ii) generating a MAC protocol data unit (MPDU) having a length such that the PHY data and the MAC data are encoded into only
the first encoding block and the second encoding block;

wherein the MAC data includes a sector sweep (SS) field having a direction field, a countdown field, and a sector identifier
field; and

wherein the MAC data omits
an information element identifier that identifies the SS field, and
a length identifier that specifies a length of the SS field.
