Indication method and device for downlink service data

Abstract

The present application provides a method and device for indicating downlink service data. The method includes: a first station STA associated with a wireless access point AP controls a wake-up receiver of the first STA to wake up within a preset first listening interval, and receives a wake-up beacon frame sent by the AP; The wake-up beacon frame includes an indication field for indicating whether the AP has downlink service data to be sent to the first STA; the first STA controls that the main radio MR of the first STA does not need to listen Waking up within an interval to receive a beacon frame sent by the AP; the first STA determines whether there is downlink service data to be sent to the first STA in the AP according to the indication field. With the method provided in this application, the MR of the first STA does not need to wake up to receive the beacon frame broadcast by the AP within the second listening interval, which greatly reduces the frequency of MR's wake-up and reduces the power consumption of the first STA.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for indicating downlink service data. Background technique [0002] In a Wireless-Fidelity (WiFi for short) network, a considerable part of the energy of the receiving end device is wasted in idle listening when there is no received signal, that is, when the station (Station, STA for short) does not send and receive messages, if the Monitoring the channel will consume a lot of energy, so the sleep mechanism (SleepSchedule) is introduced in the communication standard so that the STA can enter the deep sleep (Deep Sleep) state when there is no data to send and receive, so as to reduce the energy consumption of continuous monitoring. However, when the STA is in deep sleep, the access point (Access Point, AP for short) cannot communicate with the STA, and the transmission between the two can only be performed after the STA wakes up, which may cause a cer...

AI Technical Summary

Problems solved by technology

[0004] However, for some sites with WUR that have very strict power consumption requirements, such as sites equipped with button batteries (such as sensors), the downlink service data sent by the AP to this type of site accounts for a very small proportion of the entire data service transmission. If the above-mentioned WUR is equipped The MR of the site wakes up to receive beacon frames within the listening interval according to the 802.11 mechanism. The MR wakes up frequently, and the power consumption of the site is relatively high.
