8. A method for receiving Acknowledgement/Negative acknowledgement (ACK/NACK) information in a mobile communication system, the method comprising:
-
receiving first and second spread ACK/NACK information on four available neighboring subcarriers, the first and second spread ACK/NACK information being transmitted from a transmitting end via multiple antennas, wherein the first spread ACK/NACK information originates from spreading of first ACK/NACK information using an orthogonal sequence with a spreading factor of 2, wherein the second spread ACK/NACK information originates from spreading of second ACK/NACK information using an orthogonal sequence with the spreading factor of 2, and wherein the first and second spread ACK/NACK information is transmitted from the transmitting end in a state of being coded on the four available neighboring subcarriers of the multiple antennas in a form as shown in Table 1 or 2; - View Dependent Claims (9, 10, 11, 12, 13, 14)
