Disclosed in the present invention are an out-of-band full duplex-based data transmission method, an access point, and a station. The method comprises: sending scheduling information to a first station over a first channel, said scheduling information being used for scheduling the first station to send an uplink data frame; in a first time period after sending said scheduling information, acquiring self-interference channel estimation information of the first channel; on the basis of the self-interference channel estimation information of the first channel, and after said first time period, receiving the uplink data frame sent over the first channel by the first station on the basis of the scheduling information; and sending a downlink data frame to a second station over a second channel, part or all of the time of the uplink data frame and the downlink data frame overlapping, but the carrier frequency of the first channel and the second channel being different. The out-of-band full duplex-based data transmission method, access point, and station set forth in the embodiments of the present invention can implement out-of-band full duplex communication of communication nodes and improve the frequency spectrum efficiency of a system. |
