DEVICE AND METHOD FOR HANDLING HARQ FEEDBACK IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A device and method for handling HARQ(Hybrid Automatic Repeat reQuest) feedback in a wireless communication system are provided to perform HARQ operation without a malfunction by integrating a plurality of forward direction carriers and reverse direction carriers. CONSTITUTION: An HARQ processing method comprises the steps of: analyzing a control message which is transmitted from a base station, and sensing HARQ feedback provision between a forward carrier and a reverse carrier(1105); and deciding which reverse carrier or forward carrier HARQ feedback needs to be transmitted to or received from in response to forward traffic or reverse traffic transmitted to any desired carrier at any desired time(1115); and transmitting a reverse feedback through the reverse carrier(1120).
