Abstract:
A method and apparatus for transmitting and receiving control information in an SC-FDMA system are provided. Different orthogonal codes are generated for different slots each including a plurality of SC-FDMA symbols in a subframe. A control channel signal is generated by multiplying control symbols carrying control information by a sequence allocated for CDM of the control information. The control channel signal is multiplied by chips of the orthogonal codes on an SC-FDMA symbol basis and transmitted in the SC-FDMA symbols.
