Abstract: A method for indicating a frame structure in a wireless local area network (WLAN) is provided. A sending device generates a transmission frame. The transmission frame includes a physical header. The physical header includes a frame structure indication field. A subcarrier polarity of the frame structure indication field is used to indicate the frame structure of the transmission frame. The sending device sends the transmission frame to a receiving device. In the transmission frame, a first subcarrier polarity indicates the transmission frame has a first frame structure, and a second subcarrier polarity indicates the transmission frame has a second frame structure, so that the receiving device determines the frame structure of the transmission frame according to the subcarrier polarity of the frame structure indication field.
