Abstract

See full text

A communication device receives a physical layer (PHY) data unit having a PHY preamble with a non-legacy signal field. The non-legacy signal field includes a multi-bit signal field header that occupies a beginning portion of the non-legacy signal field. A plurality of available values of the multi-bit signal field header includes i) at least one available value corresponding to a wireless communication protocol, and ii) multiple other available values reserved for at least one of i) at least one future version of the wireless communication protocol, and ii) at least one future wireless communication protocol. The multi-bit signal field header indicates a field format of other subfields of the non-legacy signal field that follow the multi-bit signal field header. The communication device processes the beginning portion of the non-legacy signal field to determine a field format of the other subfields of the non-legacy signal field.
