Method, access point and system for transmitting multi-site control frame

Abstract

The embodiments of the present invention disclose a method, an access point and a system for transmitting a multi-site control frame. The method includes: sending a multi-site control frame to the multi-site, wherein, when the multi-site control frame is a request frame, the request frame is used to request each site in the multi-site to send a first response frame corresponding to the multi-site control frame; Receive the first response frame corresponding to the multi-site control frame sent by each site in the multi-site; or, when the multi-site control frame is the second response frame, the second response frame is used to respond to the data frame transmitted by the multi-site or A management frame, or a control frame; wherein, the multi-site control frame includes: a traditional preamble field and a new preamble field. The new preamble field includes: a first signaling field, and a second signaling field. Compared with the 802.11ax multi-site control frame, the number of bytes occupied by the multi-site control frame has been greatly reduced. Therefore, the time that the multi-site control frame occupies the channel during the transmission process can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, access point and system for transmitting multi-site control frames. Background technique [0002] In the prior art, the battery capacity of terminal equipment is limited, and even some terminals use button batteries. 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 simultaneously send and receive data and improve system throughput, 802.11ax introduces Orthogonal Frequency Division Multiple Access (OFDMA) transmission technology. Correspondingly, a multi-site control frame is also introduced, such as a multi-site block acknowledgment frame (Multi-STA Block Ack, M-BA for short). In the WiFi protocol of the Internet of Things, there may still be multi-site scheduled transmissions such as 802.11ax. In order to reduce the power consum...

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
