Problems solved by technology

If there is no AP on a channel, the STA will not receive any reply after sending the probe request frame, but since the STA does not know in advance that there is no AP on the channel, it still needs to monitor the channel until the timeout, so STA power consumption is too large
[0003] At present, there is no perfect mechanism to reduce the power consumption during the communication between STA and AP, so a new mechanism is needed to reduce the power consumption of the station

Embodiment Construction

[0160] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the corresponding drawings.

[0161] figure 1 It is an exemplary schematic diagram of a wireless local area network (Wireless Local Area Networks, WLAN) 100 according to an embodiment of the present invention. like figure 1 As shown, a wireless local area network 100 includes an access point (Access Point, AP) 102 and stations (Station, STA) 104-106, wherein the stations 104-106 can communicate with the access point 102 through wireless links.

[0162] Currently, standards adopted by the WLAN are Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE for short) 802.11 series standards. A WLAN may include multiple Basic Service Sets (BSS for short), and the nodes of the Basic Service Set are stations STA, and the stations include access point stations (Access Point, AP for short) and non-a...

Abstract

Embodiments of the present invention provide an access method, a station, and an access point. The access method includes: the main communication module of the station sends a request frame, and the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the main communication module; the main communication module of the station starts the wake-up radio WUR module, so The main communication module enters the sleep state; the WUR module receives the wake-up frame from the access point; the WUR module starts the main communication module, and the WUR module enters the sleep state. The access method provided by the embodiment of the present invention reduces the power consumption of the station by reducing the waiting time of the station for communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access method, a station and an access point. Background technique [0002] In a traditional 802.11 system, during communication between a station (Station, STA) and an access point (Access Point, AP), in many communication links, the STA needs to continuously monitor, resulting in excessive power consumption. For example, in a traditional 802.11 system, an STA needs to send a probe request frame (Probe Request Frame) to perform active scanning, so as to determine whether there is an available AP nearby. Normally, STA traverses one or more channels. For each channel, STA sends a probe request frame on the channel, and then waits for the AP to reply a probe response frame (Probe Response Frame) on the channel. If no Probe Response frame is received, the STA switches to the next channel to continue sending Probe Request frames, and waits for the Probe Response fr...
