METHOD OF TRANSMITTING CONTROL INFORMATION IN MULTIPLE CARRIER SYSTEM

摘要

PURPOSE: In a multiple carrier wave system, by defining the mapping form between uplink carrier waves and down link carrier waves the control information transmission method transmits the HARQ ACK/NACK information according to the mapping form defining. CONSTITUTION: A terminal receives the carrier wave mapping information from the base station(S410). The carrier wave mapping information comprises the information about mapping to the second link carrier wave in the first link carrier wave. As to HARQ about downlink data, the first link and the second link are respectively used as the down link and uplink. As to HARQ about upward link data, the first link and the second link are respectively used as uplink and down link.
