SYSTEMS AND METHODS FOR WIRELESS COMMUNICATION OF PACKETS HAVING A PLURALITY OF FORMATS

摘要

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.

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 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; andinterpret 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.
