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.

摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a first signal is generated for transmission to a wireless node to enable the wireless node to determine a first preferred beam pattern. A second preferred beam pattern is determined from a second signal received from the wireless node. The apparatus communicates with the wireless node through at least one of the first or second preferred beam pattern.
