    摘要： This application discloses midamble indication and receiving methods and apparatuses. In the method, a first device sends midamble indication information to a second device, where a duration of a midamble indicated by the midamble indication information is greater than or equal to a threshold, and the threshold is related to a processing capability of the second device; and the second device receives the midamble according to the indication information. In the foregoing method, the first device sends the midamble indication information to the second device, so that the second device can receive the midamble according to the indication information. Furthermore, a duration of processing the midamble does not significantly increase as the duration of the midamble increases. Therefore, the fact that the duration of the midamble is greater than or equal to the threshold helps avoid a case in which after receiving the midamble, the second device may have no time to correctly decode a data symbol based on the midamble due to the limited processing capability.

    摘要： Embodiments of the present invention provide a method for transmitting a physical layer protocol data unit PPDU, including: some data subcarriers of a last orthogonal frequency division multiplexing OFDM symbol that carries useful information and that is in the PPDU carry a data symbol sequence, the other data subcarriers of the last OFDM symbol that carries useful information carry a feature signal sequence, and a starting position of the feature signal sequence is determined by parsing the PPDU. The embodiments of the present invention further provide a corresponding PPDU transmission apparatus. Application of the method and apparatus in the embodiments of the present invention enables a receive end to quickly determine the starting position of the feature signal sequence by means of blind detection, and ensures that the receive end quickly completes data processing and state switching.
