The embodiment of the invention discloses a data transmission method and device, which relates to the field of communication, and solves the problem of waste of transmission resources caused by downlink data transmission using only part of symbols contained in DwPTS. Specifically, the network device transmits the second downlink data on the second time interval, in which the second time interval is located in the second time slot in the first special subframe or the first time slot in the second special subframe, the first special subframe is a special subframe whose downlink pilot slot duration is greater than 0.5 milliseconds, and the second special subframe is a special subframe whose downlink pilot slot duration is less than 0.5 milliseconds. Special subframe, the second time interval contains N symbols, N is greater than or equal to 2, and less than or equal to 6 integers. The embodiment of the present invention is used in the process of data transmission.
