摘要：
Methods and apparatus are provided for transmitting control information in an SC-FDMA system. A UE generates a random cyclic shift value based on an SC-FDMA symbol index and a slot index. The UE cyclically shifts a sequence by the random cyclic shift value. The UE multiplies a control channel signal, including the control information, by the cyclically shifted sequence on an SC-FDMA symbol basis. The UE transmits the multiplied control channel signal in an SC-FDMA symbol to a Node B.
