1. A data transmission method, comprising:

  • coding and modulating, by a terminal device, a first transport block to obtain a first coded transport block for transmission in a transmission time interval being a minimum scheduling period, the first transport block comprising a buffer status report (BSR) indicating an amount of to-be-transmitted data currently buffered in a buffer of the terminal device;

    sending, by the terminal device, the first coded transport block comprising the BSR to a network device;

    separately coding and modulating, by the terminal device, indication information to obtain a different coded transport block comprising the indication information, the indication information being used to indicate that the terminal device sends the BSR when the terminal device sends the first coded transport block; and

    sending, by the terminal device, the different coded transport block comprising the indication information to the network device.
