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] The 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 narrowband part of the wake-up frame of the second wake-up frame is detected at the target time, and the target time is A time corresponding to a second duration from the end of the narrowband portion of the wake-up frame of the first wake-up frame, where the second duration is the sum of the frame interval and the length of the traditional preamble;

[0080] The 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 narrowband part of the wake-up frame 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 narrowband portion of the wake-up frame of the first wake-up frame, where the second duration is the interval between t...

Abstract

Embodiments of the invention disclose a site awakening method and a target site. The site awakening method can include steps: an awakening receiver receives a first awakening frame transmitted by an access point, wherein a receiving address of the first awakening frame is matched with an address of the target site; the awakening receiver detects whether an idle duration of a channel reaches a first duration, if the first duration is greater than a frame pitch, the frame pitch refers to a pitch between any two adjacent frames in a plurality of frames continuously transmitted by the access point; and if the idle duration of the channel reaches the first duration, the awakening receiver awakens a main transceiver of the target site. By employing the method and the target site, whether the main transceiver of the target site is awakened is determined according to the idle duration of the channel so that the access point awakens a plurality of sites and broadcasts or multicasts scenes of radio frames to the plurality of sites, and the power consumption of the target site is reduced.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for waking up a site and a target site. Background technique [0002] In Wireless Fidelity (Wi-Fi) networks, a considerable part of the device energy is wasted in idle listening when there is no signal. The current traditional 802.11 protocols (802.11b / a / g / n / ac, etc.) The related solutions in) focus on optimizing the sleep strategy of the device. In addition to optimizing the sleep strategy, another technical way to reduce energy waste when the device is idle for monitoring is to wake up the receiver with low power consumption. In addition to the traditional 802.11 main transceiver, the site has 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 the station, first send a wake-up frame (Wake Up Packet, WUP) to the wake-up receiver of the sta...
