Abstract

The invention discloses a decoding generation method and device of a wakeup frame. The method comprises the following steps: an access point constructs the wakeup frame of a first mode, wherein the wakeup frame comprises a leader part which is located at the starting part of the wakeup frame, and the leader code part of the wakeup frame of the first mode carries an identifier of a site in an implicit way; and the access point sends the wakeup frame of the first mode. Through the method disclosed by the invention, the energy consumed for decoding the wakeup frame by the site can be reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a wake-up frame generation and decoding method and device. Background technique [0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcast. In a typical wireless communication system, an access point can support communication with multiple stations by sharing available system resources (eg, bandwidth, transmit power). These sites may be mobile terminals, sensors, smart devices, meters, instruments, monitors and devices, etc. These stations usually use batteries for power supply, and the battery life is very limited. In order to save power, the stations often put the main circuit into a sleep state, and only keep the low-power wake-up receiver in a working state. When the wake-up receiver receives the wake-up frame sent by the access point, it decodes the wake-up frame to obt...
