RESOURCE ALLOCATION METHOD FOR HARQ ACK/NACK AND HARQ ACK/NACK SIGNAL TRANSMITTING METHOD AND APPARATUS

摘要

PURPOSE: A method for allocating resources for transmitting a HARQ ACK/NACK(Hybrid Automatic Repeat reQuest) signal and a HARQ ACK/NACK transmission method and apparatus using the same are provided to efficiently use PUCCH(Physical Uplink Control Channel) transmission resources by sharing an ARI mapping table. CONSTITUTION: A base station transmits information necessary for transmission of a HARQ ACK/NACK signal through upper layer signaling like RRC(Radio Resource Control) signaling to a terminal(S810). The base station constitutes an ARI(ACK/NACK Resource Indicator) directing transmission resources allocated to the terminal(S820). The base station transmits necessary information to a down link-control channel and a downlink data transmission channel(S830). The terminal obtains resources transmitting the HARQ ACK/NACK signal according to the ARI(S840). The terminal transmits the HARQ ACK/NACK signal onto PUCCH by using the obtained transmission resources(S850).
