SYSTEMS AND METHODS FOR WIRELESS COMMUNICATION OF PACKETS HAVING PLURAL FORMATS

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for communicating packets having a plurality of formats.SOLUTION: 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. One or more detectors are used to auto-detect packets formatted as one of at least two different formats on the basis of a short training field (STF) of a received packet. A long training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.SELECTED DRAWING: Figure 2
