Title:
WAKE-UP PREAMBLE GENERATING METHOD, SYNCHRONIZATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/072692
Kind Code:
A1
Abstract:
Disclosed are a wake-up preamble generating method, synchronization method and apparatus, the wake-up preamble generation method comprising: generating a wake-up frame, the wake-up frame comprising a wake-up preamble, the wake-up preamble comprising a regular sequence composed of at least two sub-regular sequences, and the latter sub-regular sequence being a bit reverse sequence of a sub-regular sequence previous thereto; alternatively, comprising at least one sub-regular sequence and a preset field, the preset field being a synchronization field having an auto-correlation characteristic and a cross-correlation characteristic or being a frame start delimiter having a unique sequence; sending the wake-up frame so that a receiver completes synchronization quickly according to the content of the wake-up preamble. The present application achieves fast synchronization by means of generating a wake-up preamble that is used to synchronize a receiver so that the receiver knows an end bit of the preamble or a start bit of an information sequence.
