Abstract: A method of transmitting an acknowledgment (ACK)/non-acknowledgement (NACK) signal in a wireless communication system includes assigning at least one ACK channel among a plurality of ACK channels which share an ACK channel region for transmitting the ACK/NACK signal, and transmitting the ACK/NACK signal through the at least one ACK channel, wherein the ACK channel region includes at least one tile including a plurality of data subcarriers, and the ACK/NACK signal of each ACK channel is indicated by mapping different orthogonal vectors respectively to the plurality of ACK channels in the tile.
