Problems solved by technology

[0003] However, in some scenarios, for example, when the access point (AP, Access Point) needs to broadcast or multicast Wi-Fi wireless frames to multiple STAs, how to regulate the wake-up method of the main transceiver of the STA has not yet been determined

Embodiment approach

[0079] A first optional implementation manner is: if the idle duration of the channel does not reach the first duration, the wake-up receiver determines whether the wake-up frame narrowband part of the second wake-up frame is detected at the target time, and the target time is The moment corresponding to the second duration from the end moment of the narrowband part of the wakeup frame receiving the first wakeup frame, the second duration being the sum of the frame interval and the length of the conventional preamble;

[0080] A second optional implementation manner is: if the idle duration of the channel does not reach the first duration, the wake-up receiver determines whether the wake-up frame narrowband part of the second wake-up frame is detected at the target time, and the target time is The time corresponding to the second duration from the end of the wake-up frame narrowband portion of the first wake-up frame, where the second duration is between the frame interval, the...

Abstract

Disclosed in an embodiment of the present invention are a station wakeup method and a target station. The station wakeup method comprises: a wakeup receiver receives a first wakeup frame sent by an access point, wherein a receiving address of the first wakeup frame matches an address of the target station; the wakeup receiver detects whether an idle duration of a channel has reached a first duration, wherein the first duration is greater than a distance between frames, and the distance between frames is a distance between any two adjacent frames of multiple frames continuously sent by the access point; and if the idle duration of the channel has reached the first duration, the wakeup receiver wakes up a main transceiver of the target station. With the embodiment of the present invention, it can be determined, according to an idle duration of a channel, whether to wake up a main transceiver of a target station, so as to adapt the access point for a scenario in which the access point wakes up multiple stations and broadcasts or multicasts a wireless frame to the multiple stations, reducing power consumption of the target station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a station wake-up method and a target station. Background technique [0002] In a Wireless Fidelity (Wi-Fi) network, a considerable part of the energy of the device is wasted on idle listening when there is no received signal. The current traditional 802.11 protocol (802.11b / a / g / n / ac, etc. ) related solutions focus on optimizing the sleep strategy of the device. In addition to optimizing the sleep strategy, another technical approach to reduce energy waste when the device is idle listening is to use low power consumption to wake up the receiver. In addition to the traditional 802.11 main transceiver, the site includes a new wake-up receiver. When the main transceiver enters deep sleep, the low-power wake-up receiver wakes up and starts working. If other stations need to communicate with this station, they first send a wake-up frame (Wake Up Packet, WUP) to the wa...
