Abstract
According to one aspect of the present invention, values which are specifically defined for each user equipment are reflected when resource allocation/mapping of downlink/uplink ACK/NACK channels is performed, so as to vary uplink/downlink ACK/NACK information transmitting resources for each user equipment allocated to the same downlink/uplink resource. According to another aspect of the present invention, nodes for transmitting uplink/downlink ACK/NACK information vary for each user equipment allocated to the same downlink/uplink resource. According to the present invention, even when downlink/uplink signals for a plurality of user equipment are transmitted from the same resource, uplink/downlink ACK/NACK signals of the plurality of user equipment are transmitted from different resources, thereby reducing interferences among ACK/NACK signals of the plurality of user equipment.
