Abstract

The present disclosure provides a data transmission method and device. The method includes sensing, by a station, whether a channel allocated by an access point associated with the station is occupied, before obtaining a downlink scheduling phase. 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. The method also includes receiving, by the station in the downlink scheduling phase, data transmitted by the access point. The present disclosure ensures normal data transmission.
