Problems solved by technology

[0005] However, the disadvantage of the existing technology is that the information received by each STA must contain trigger information and MAC function information at the same time, and each STA needs to respond to the corresponding type of MAC frame according to the trigger frame type indication according to the MAC function information, which has certain restrictions. , because there may be some STAs that do not need to reply the corresponding type of MAC frame

Embodiment Construction

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but 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 creative efforts fall within the protection scope of the present invention.

[0058] The embodiment of the present invention can be applied to a WLAN, and currently the standards adopted by the WLAN are IEEE 802.11 series. WLAN can include multiple Basic Service Sets (Basic Service Set, BSS). The network nodes in the basic service set are stations, and the stations include access point stations (Access Point, AP) and non-access point stations (None Access PointStation, Non-AP STA), in the embodiment of the present invention, Non...

Abstract

Embodiments of the present invention disclose a method and device for transmitting a trigger frame in a wireless local area network. The method for transmitting a trigger frame in a wireless local area network includes: an access point generates a trigger frame carrying a target medium access control MAC function, and the trigger frame includes indication information, where the indication information is used to instruct the first station to send a MAC frame corresponding to the target MAC function, and the indication information is used to instruct the second station not to execute the target MAC function; the access point sends the trigger frame. The present invention instructs the first site to send the MAC frame corresponding to the target MAC function through the indication information without restricting the second site, thereby flexibly controlling the data sending modes of the first site and the second site.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a method and device for transmitting a trigger frame in a wireless local area network. Background technique [0002] Currently, the Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers, IEEE) is developing a next-generation wireless local area network (Wireless Local Area Network, WLAN) standard 802.11ax. 802.11ax will introduce Orthogonal Frequency Division Multiple Access (OFDMA) technology. OFDMA technology can support access points (English: Access Point, AP) to perform multi-user transmission with multiple stations (Station, STA) at the same time. Therefore, a trigger frame needs to be defined, and the trigger frame is sent by the AP to indicate resources for uplink multi-user transmission. After receiving the trigger frame, multiple STAs send uplink frames almost at the same time according to the resource scheduling informati...
