Abstract
In a wireless communication system wherein communication devices exchange information utilizing data units that conform to a first format, wherein the first format includes a short training field (STF) spread with a first spread code, a physical layer (PHY) data unit that conforms to a second format and is for transmitting PHY control information is generated. Generating the PHY data unit includes generating a first portion of the PHY data unit to indicate the PHY data unit conforms to the second format, wherein the first portion of the PHY data unit includes an STF spread with a second spread code different than the first spread code. A second portion of the PHY data unit is generated according to the second format, wherein the second portion of the PHY data unit omits header fields specified by the first format.
