The wireless communication device generates a physical layer (PHY) preamble of the PHY data unit to include a legacy signal field in a legacy portion of the PHY preamble and a non-legacy signal field in a non-legacy portion of the PHY preamble, the non-legacy signal field generated to include the TXOP field.
