Disclosed are a data transmission method and device. The method comprises: determining the frequency domain position in the physical resource block during the time slot for sending TTI Bundling by a frequency hopping mode according to a TTI Bundling parameter, wherein, the frequency hopping variable i of the frequency hopping mode is determined according to the TTI Bundling parameter by means of the following predetermined approach or the combinations thereof: mod is modulus operation, floor is rounded down operation, ns is the sequence number of the time slot; transferring data over the time frequency resource corresponding to the frequency domain position in the physical resource block during the time slot of the TTI bundling. According to the invention, the coverage area of the TTI bundling data transmission is improved. |
