Abstract: This application provides a method and apparatus for transmitting a physical layer protocol data unit, so as to design a long training field sequence for a larger channel bandwidth. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a long training field, a length of a frequency domain sequence of the long training field is greater than a first length, and the first length is a length of a frequency domain sequence of a long training field of a PPDU transmitted over a channel whose bandwidth is 160 MHz; and sending the PPDU over a target channel, where a bandwidth of the target channel is greater than 160 MHz.

Abstract: This application relates to the field of communications technologies, and discloses a data transmission method. The method includes: generating a PPDU; and transmitting the PPDU to at least one receive end. The PPDU includes a channel estimation field CEF, and the CEF includes a plurality of sub-sequences. For each of the plurality of sub-sequences, a part or all of elements in the sub-sequence are basic elements, and the basic elements are arranged into a Golay sequence or a ZC sequence in the sub-sequence. This application is used for data transmission.
