Disclosed is a data communication method, comprising: sending, by a station, serial numbers to at least two access points, each of the serial numbers being used for indicating the sequence for each access point to respond to the station; broadcasting wakeup messages to the at least two access points, the wakeup messages being used for notifying the at least two access points, and the station being in a wakeup state; receiving acknowledgement messages which are sequentially returned by the at least two access points according to the respective serial numbers, the acknowledgement messages being used for indicating whether the access points need to transmit downlink data; according to the sequentially returned acknowledgement messages, confirming whether the corresponding access points need to transmit the downlink data; and according to the serial numbers, completing, by the station, downlink data transmission in sequence, together with the access points needing to transmit the downlink data. Also disclosed are a station, an access point and a system. By means of the present invention, a station in an OBSS system can acquire information returned by a plurality of access points in a single wakeup, thereby reducing the power consumption of the station. |
