First Claim
1. A data processing method, comprising:
- receiving, by a terminal, mapping relationship information sent from a base station, wherein the mapping relationship information is used to indicate a mapping relationship between a hybrid automatic repeat request (HARQ) entity of the terminal and a frequency resource configured by the base station for the terminal;
determining, by the terminal, the frequency resource;
determining, by the terminal according to the mapping relationship information, a HARQ entity corresponding to the frequency resource; and
processing, by the terminal by using the HARQ entity, a HARQ data block transmitted on the frequency resource,wherein the frequency resource comprises a configured carrier,wherein the determining, by the terminal, the frequency resource comprises;
determining, by the terminal, the configured carrier according to scheduling grant signaling that comprises a configured carrier identifier and that is sent from the base station,wherein the scheduling grant signaling further comprises an indication message of a HARQ entity corresponding to the configured carrier, andwherein the determining, by the terminal according to the mapping relationship information, the HARQ entity corresponding to the frequency resource comprises;
determining, by the terminal according to the indication message, the HARQ entity corresponding to the configured carrier.

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.
