Abstract
Embodiments described herein provide a method for null data packet transmission. An information symbol is obtained for transmission in a null data packet. A set of tones for transmitting the information symbol is obtained and divided into a first subset of tones and a second subset of tones. A first value is transmitted over the first subset of tones and a second value is transmitted over the second subset of tones to indicate a feedback information bit of zero from the information symbol. A third value is transmitted over the first subset of tones and a fourth value is transmitted over the second subset of tones to indicate a feedback information bit of one from the information symbol.
