1. An apparatus for wireless communication, comprising:

  • a receiver configured to receive a wireless communication comprising a physical layer preamble and a payload, the preamble including a first field indicating whether the preamble includes an extension field, the first field comprising a first signal field, and a rotation of a modulation of the first signal field being an indicator that the extension field is included in the wireless communication, the first field further including a first sub-field including a length indicator of the wireless communication; and

    a processor in connection with a memory, the processor being configured to;

    process the payload based on coding parameters included in the first field when the rotation of the modulation of the first signal field indicates that the preamble does not include the extension field;

    process the payload based on coding parameters included in the extension field when the rotation of the modulation of the first signal field indicates that the preamble includes the extension field; and

    interpret the first sub-field as an indicator of a number of bytes or interpret the first sub-field as an indicator of a number of symbols, the interpreting being based on a value of the extension field.
