Title: METHOD AND DEVICE FOR DATA TRANSMISSION
Abstract:
Provided in embodiments of the present invention are a method and device for data transmission. The method comprises: a terminal device transmits a first data packet to a network device on a first time unit via a GUL transmission scheme, the first data packet corresponding to a first HARQ process number, and the first data packet corresponding to first new data indication information; the terminal device receives first instruction information transmitted by the network device, the first instruction information being used for instructing the terminal device to transmit a second data packet on a second time unit, the second data packet corresponding to the first HARQ process number, where the second data packet corresponding to second new data instruction information transmitted by the network device; and the terminal device either buffers the first data packet or transmits the second data packet on the basis of the value of the first new data instruction information and of the value of the second new data instruction information. Hence, the problem of data packet loss can be mitigated and the reliability of data transmission increased.
