The invention relates to the field of wireless communication technology, in particular to data transmission method, device and system, so as to provide a scheduling plan for data transmission with transmission time interval TTI less than 1 sub frame length or TTI less than 1ms. The processing module in a base station provided by the embodiment of the invention, and is used to determine the size of resource scheduling; resource scheduling according to the size, short TTI data transmission resources determine the terminal equipment for data transmission by using the short TTI data transmission resources in the time domain is less than 1 or less than the length of the sub frame transceiver module, used to 1ms; terminal equipment to transmit downlink control information DCI, indicating TTI data transmission resources, and data transmission using short TTI data transmission resources and terminal equipment. In the embodiment of the invention, the DCI sent by the base station indicates the short TTI data transmission resources to the terminal device, and realizes the scheduling for data transmission with TTI less than 1 sub frames or less than 1ms.
