Embodiment Construction

[0044] The present application can be applied to a wireless local area network (Wireless Local Area Networks, WLAN for short), and currently WLAN adopts the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE for short) 802.11 series. Wherein, a station (Station, STA for short) and an access point (Access Point, AP for short) are basic components of a WLAN.

[0045] Among them, AP is the access point for mobile users to enter the wired network. It is mainly deployed in homes, buildings, and campuses. The typical coverage radius is tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. The AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless network to the Ethernet. Specifically, the AP may be a terminal device or a network device with a WiFi (English: Wireless F...

Abstract

The invention provides a method and device for indicating channel access. The method comprises the steps that first communication equipment receives a channel synchronization request sent by second communication equipment, wherein the channel synchronization request is used for requesting the first communication equipment to send a synchronization frame to the second communication equipment, and the second communication equipment is configured with a wake-up receiver; the first communication equipment sends the synchronization frame to the awakened second communication equipment when the channel is idle according to the channel synchronization request and the wake-up time, which is learnt by the first communication equipment according to preset signaling, of the second communication equipment, wherein the synchronization frame is used for indicating the awakened second communication equipment to access to the channel after receiving the synchronization frame. According to the method provided by the invention, the second communication equipment can access to the channel without waiting for probe delay time when being awakened, thereby greatly shortening the waiting time of a main transceiver of the second communication equipment, and saving the power consumption caused by the waiting of the second communication equipment.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for indicating channel access. 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 certain de...
