Abstract: The present invention includes a data processing method used for implementing data transmission between multiple carriers and a HARQ entity. A terminal receives mapping relationship information sent from a base station, where the mapping relationship information is used to indicate a mapping relationship between a HARQ entity of the terminal and a frequency resource configured by the base station for the terminal. The terminal determines frequency resource. The terminal determines a HARQ entity corresponding to the frequency resource according to the mapping relationship information, and processes a HARQ data block transmitted on the frequency resource by using the HARQ entity. Therefore, carrier communication channels for real-time transmission between the base station and the terminal are increased, to improve transmission efficiency.
