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.

Abstract
Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.

17. An apparatus for wireless communication, comprising a processor in connection with a memory, the processor being configured to:
-
generate a wireless communication comprising a physical layer preamble and a payload and to determine whether to include an extension field in the preamble, the preamble including a first field indicating whether the preamble includes the 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, the first sub-field further being an indicator of a number of bytes or an indicator of a number of symbols, and the indicator of a number of bytes or a number of symbols being based on a value of the extension field; include coding parameters for the payload 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; include coding parameters for the payload 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. - View Dependent Claims (18, 19, 20, 21, 22, 23)
