Claim Text:
1. A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel in a wireless communication system, the method comprising: grouping ACK/NACK signal channels into a plurality of groups based on uplink resource block indexes so that ACK/NACK signal channels of consecutive uplink resource blocks do not belong to the same group, wherein each ACK/NACK signal channel is used to transmit a downlink ACK/NACK signal in response to a data channel received through a respective one of a plurality of uplink resource blocks; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.
