Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0052] figure 1 is a schematic diagram of a typical application scenario of a WLAN. Such as figure 1 As shown, the WLAN includes access points (AccessPoint, AP) and stations (Station, STA). The AP is responsible for two-way communication with multiple STAs, such as figure 1 The AP shown in figure 1 STA1 and STA2 in ) to send downlink data, or the AP receives data from STA (such as figure 1 STA3) in the uplink data. It should be understood that figur...

Abstract

The invention discloses a scheduling method, an access point and a station. The method includes: an access point AP generates a first frame, the first frame includes reservation information of each trigger frame in at least one trigger frame, and the first The trigger frame is any one of the at least one trigger frame, and the reservation information of the first trigger frame includes the identifier of the first trigger frame, the start time of the first trigger frame, and the first A constraint condition of the station STA corresponding to the trigger frame; the AP broadcasts the first frame to at least one STA. Therefore, in the method provided by the present invention, the AP notifies the STA of the reservation information of each trigger frame in at least one trigger frame by broadcasting the first frame, and the reservation information includes the identification of the trigger frame, the start time and the constraints of the corresponding station STA , the unified scheduling of APs can support the dynamic changes of the network, which is conducive to the coordination between APs and STAs, so as to achieve a better effect of saving STA power consumption.

Description

technical field [0001] The present invention relates to the field of wireless local area network, and more specifically, relates to a scheduling method, an access point and a station. Background technique [0002] With the rapid development of communication technology, the Internet of Things (IoT) has penetrated into all aspects of work and life. When an IoT device is installed on a wall or a floor, large penetration loss will occur due to occlusion, so that the IoT device consumes more power. The IoT device here is a station (Station, STA). In order to overcome this problem, a trigger frame (Trigger Frame, TF) mechanism is usually used in data transmission at present. When a STA does not need to perform data transmission, it enters the dormant state, thereby saving the power consumption of the STA, and the STA releases the time-frequency resource; the access point (Access Point, AP) triggers other STAs to use the time-frequency resource through TF . [0003] In the exist...
