Abstract
A method and apparatus for transmitting and receiving control information in an SC-FDMA system are provided, in which different cyclic shift values are generated for different SC-FDMA symbols in one of a slot and a subframe, a sequence allocated for CDM of control information is cyclically shifted by the cyclic shift values, and a control channel signal including the control information is combined with the cyclically shifted sequences on an SC-FDMA symbol basis and transmitted in the SC-FDMA symbols.
