Abstract: This application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for transmitting a physical layer protocol data unit, and for example, is applied to a wireless local area network. The method includes: A first communications device generates a PPDU and may send the PPDU, where the PPDU includes an LTF sequence; and correspondingly, a second communications device receives the PPDU, and parses the PPDU to obtain the LTF sequence included in the PPDU. Embodiments of this application can be used to design an LTF sequence that has a relatively low PAPR on entire bandwidth, on a single resource unit, on a combined resource unit, and in a considered multi-stream scenario.

Abstract: This application discloses a data transmission method and device, a chip system, and a computer-readable storage medium. In the method, a station may receive preamble puncturing indication information that includes one or more indicators. An indicator of the one or more indicators corresponds to preamble puncturing information of a data packet. The station sends or receives the data packet based on the preamble puncturing indication information. The preamble puncturing information includes a size and location of preamble puncturing, or that there is no preamble puncturing. The preamble puncturing information may be an index indicated by the preamble puncturing indication information, to learn of a status of preamble puncturing in the data packet.
