Abstract
A method for allocating resources for transmission of an uplink Acknowledgement (ACK)/Negative ACK (NACK) used for indicating success/failure in reception of downlink transmission data by a base station in a mobile communication system. The resource allocation method includes determining a mapping rule between control channel elements constituting a downlink control channel and resources for ACK/NACK transmission; transmitting, to at least one User Equipment (UE), control information used for indicating to acquire the determined mapping rule and resources for ACK/NACK transmission allocated using the mapping rule; transmitting a downlink data channel though a predetermined scheduling operation; and transmitting the downlink control channel to the UE.
