THE METHOD FOR DETECTING HARQ ACK/NACK FEEDBACK SIGNAL AT A RELAY NODE

摘要

PURPOSE: A HARQ ACK/NACK feedback signal detection method in a relay is provided to efficiently receive a HARQ ACK/NACK feedback signal by using a new HARQ ACK/NACK channel structure and a transmission method. CONSTITUTION: A specific channel configuration information is received. The specific channel configuration information comprises the start point of the specific channel of the HARQ ACK/NACK feedback signal which is transmitted from a base station and offset information which represent the location of a specific channel allocated to the relay inside the specific channel. The HARQ ACK/NACK feedback signal about the uplink transmission of the relay is received from the base station. The received HARQ ACK/NACK feedback signal is decoded.
