The present invention provides a data transmission method and device. The method includes: before obtaining a downlink scheduling phase, sensing, by station, whether a channel allocated by an access point associated with the station is occupied; if the channel is not occupied, sending, by the station, channel clear signaling to the access point, where the channel clear signaling includes a first identifier used for identifying the station and a second identifier used for identifying the access point; and receiving, by the station in the downlink scheduling phase, data transmitted by the access point. The present invention ensures normal data transmission. |
