Abstract
A method for transmitting Acknowledgement/Negative acknowledgement (ACK/NACK) information in a communication system includes spreading first ACK/NACK information using an orthogonal sequence with a spreading factor of 2, spreading second ACK/NACK information using an orthogonal sequence with the spreading factor of 2, and coding the first and second spread ACK/NACK information on four available neighboring subcarriers of multiple antennas.
