Abstract
The present invention provides a method, a device and a system for transmitting data, which relate to the field of network technology. A station sends a request-to-send frame to an access point to obtain a channel, at the same time, the access point actively sends a middle-clear-to-send frame, so as to indicate which stations can send data, thereby reducing the time overhead in the data transmission process, improving the flexibility of the system, and avoiding system errors. Specifically, the method includes: an access point AP receives a request-to-send RTS frame sent by a station STA; sends a middle-clear-to-send MCTS frame to a scheduled STA; receives an F frame sent by the scheduled STA according to the MCTS frame; sends a final-clear-to-send FCTS frame to another scheduled STA; and receives data sent by the another scheduled STA according to the FCTS frame. The present invention is applied to data transmission.
