A method, device and system for indicating transmission frame structures, which can be used to indicate multiple different transmission frame structures and can be used in HEW to which one or more transmission modes comprising a UL OFMDA transmission mode, a DL OFDMA transmission mode and a UL MU MIMO transmission mode are introduced. In some feasible implementation manners of the present invention, the method comprises: send a transmission frame generated by a device, a physical header of the transmission frame comprising a frame structure indication field, and the subcarrier polarity of the frame structure indication field being used for indicating a frame structure of the transmission frame; when the subcarrier polarity of the frame structure indication field is a first subcarrier polarity, the transmission frame is of a first frame structure; when the subcarrier polarity of the frame structure indication field is a second subcarrier polarity, the transmission frame is of a second frame structure; and send the transmission frame, so that the reception device determines the frame structure of the transmission frame according to the subcarrier polarity of the frame structure indication field. |
