TIMING METHOD AND APPARATUS FOR HYBRID AUTOMATIC REPEAT REQUEST

摘要

A timing method and apparatus for Hybrid Automatic Repeat Request (HARQ) are provided by the present invention. The method includes: determining the feedback time according to predetermined parameters (400), transmitting the feedback message of HARQ at the feedback time (401). The predetermined parameters include one of the following or the combinations of: time for processing data by the terminal TprocMS, time for processing data by the base station TprocBS, transmission time interval (TTI), number of sub-frames in one frame F and protecting time P. By the method of the present invention, once the terminal completes the process for the data packet, it can perform transmission without waiting for the appearance of a fixed frame number. So it is guaranteed that the terminal or the base station can complete HARQ feedback within the shortest time. Too long waiting time for feedback is avoided and the speed for HARQ feedback is improved.
