Claim:
1. A method for generating a beamforming training (BFT) unit, the method comprising: generating, at a communication device, a physical layer (PHY) preamble of the BFT unit; generating, at the communication device, a PHY header of the BFT unit to include PHY data; generating, at the communication device, a fixed-length payload of the BFT unit to include media access control layer (MAC) data, wherein the MAC data (i) includes a sector sweep (SS) field having a direction subfield, a countdown subfield, and a sector identifier subfield, and (ii) omits (a) an information element identifier that identifies the SS field, and (b) a length identifier that specifies a length of the SS field; and generating, at the communication device, the BFT unit to include the PHY preamble, the PHY header and the fixed-length payload.
