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.
