A method of data transmission is provided, including: the terminal device receives the first DCI and second DCI, in which the first DCI is used for the dispatch of the terminal device to receive the first PDSCH using the first TTI transmission in the target carrier, and the second DCI is used for the dispatch of the terminal device to receive second of the second TTI transmission in the target carrier. PDSCH, and the first TTI is less than the second TTI, and the first PDSCH overlaps at least partially on the time resource; determines the priority relationship of the first DCI and the second DCI; according to the priority relationship, the first PDSCH or the second PDSCH is received in the target carrier. The method provided by the embodiment of the invention can dynamically support multiple TTI data transmission in the same carrier, and the terminal device can determine the priority of the transmission channel in a carrier. This method can satisfy both the requirement of time delay and the compatibility with the existing system.
