Method for transmitting multistation control frame, access point, and system

Abstract

The embodiment of the invention discloses a method for transmitting a multistation control frame, an access point, and a system. The method comprises the steps: transmitting the multistation control frame to multiple stations, wherein when the multistation control frame is a request frame, the request frame is used for requesting each station for transmitting a first response frame corresponding to the multistation control frame; receiving first response frames which are transmitted by all stations and are corresponding to the multistation control frame; or enabling a second response frame tobe used for responding to a data frame, a management frame or a control frame transmitted by multiple stations when the multistation control frame is the second response frame. The multistation control frame comprises a conventional lead code field and a new lead code field. The new lead code field comprises a first signaling field and a second signaling field. The multistation control frame, compared with an 802.11ax multistation control frame, greatly reduces the occupied bytes. Therefore, the method can reduce the time in occupying a channel in a transmission process of the multistation control frame.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, an access point and a system for transmitting a multi-site control frame. Background technique [0002] In the prior art, the battery capacity of the terminal equipment is limited, and even the battery used in some terminals is a button battery. Therefore, how to reduce the power consumption of the terminal equipment is a key concern of the next-generation WiFi protocol. [0003] In order to support multiple sites to transmit and receive data at the same time and improve the throughput of the system, 802.11ax introduces the Orthogonal Frequency Division Multiple Access (OFDMA) transmission technology. Correspondingly, multi-station control frames, such as multi-station block acknowledgment frames (Multi-STA Block Ack, M-BA for short), are also introduced accordingly. In the IoT WiFi protocol, there may still be multi-site scheduling transmissions...

AI Technical Summary

Problems solved by technology

[0009] Depend on figure 1 It can be seen that the MAC frame field in the multi-site block confirmation frame occupies too many bytes (more than 22 bytes), and the Internet of Things WiFi protocol uses narrowband and low-rate transmission, which will eventually lead to frame transmission time Too long, making the terminal power consumption increase
