Problems solved by technology

[0004] However, in the prior art, the information contained in the physical layer frame sent by the AP either prevents all STAs from entering the sleep state, or can only control a certain STA or STAs belonging to the same Group ID not to enter the sleep state. Support simultaneous control of the sleep state of STAs belonging to different Group IDs

Embodiment Construction

[0033] In order for those skilled in the art to further understand the features and technical contents of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0034] In the prior art, the structure of the 802.11ac physical layer frame sent by the AP is as follows figure 2 As shown, VHT-SIG-A is divided into two parts, VHT-SIG-A1 and VHT-SIG-A2, and the content represented by VHT-SIG-A1 is shown in the following table:

[0035]

[0036] Among them, TXOP_PS_NOT_ALLOWED is used to indicate whether power saving is allowed, 0 means power saving is allowed, and 1 means power saving is not allowed.

[0037] The existing power saving techniques are as follows:

[0038] When TXOP_PS_NOT_ALLOWED in the frame received by the station is 0 and one of the following conditions is met, i...

Abstract

An embodiment of the invention provides a method for controlling sites to enter a sleeping state and sites. The method includes that a receiving site receives frames of a physical layer sent by access points, wherein the frames of the physical layer includes identification information of sites, and the identification information is used for indicating the sites corresponding to the identification information to enter the sleeping state or out of the sleeping state; then the receiving site controls the sleeping states of the sites according to the identification information of the sites. By the method, the sleeping states of SAT belonging to different Group ID are controlled simultaneously through the access points, power saving scheduling can be carried out flexibly through the access points, and thus, power saving effect of BSS(base station subservice) network is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a station for controlling a station to enter a sleep state. Background technique [0002] A basic service set (Basic service set, BSS) is a basic component of a wireless local area network (Wireless Local area network, WLAN). Stations (Stations, STAs) that are within a specific coverage area and have certain associations form a BSS. Such as figure 1 As shown, for an independent BSS, such as BSS1 in the figure, each station STA1 and STA2 communicate directly with each other. Association, the BSS established around the AP is called a BSS with infrastructure, and the BSS with infrastructure can be connected to each other by their APs through a distributed system (Distribution system, DS), such as BSS2 and BSS3. [0003] Based on the above 802.11 network architecture, the AP communicates with each STA by sending 802.11ac physical layer frames, which contain mul...
