1. A method for transmitting control information in a single-carrier frequency division multiple access communication system, the method comprising:

  • determining a channel quality indicator (CQI) and two acknowledgements;

    generating a first symbol based on the CQI;

    generating a second symbol based on the two acknowledgements, if both the CQI and the two acknowledgements are to be transmitted on a physical uplink control channel (PUCCH); and

    transmitting the first symbol and the second symbol on the PUCCH,wherein 1 is applied for generating the second symbol if the two acknowledgements have a first value, −

    1 is applied for generating the second symbol if the two acknowledgements have a second value, j is applied for generating the second symbol if the two acknowledgements have a third value, and −

    j is applied for generating the second symbol if the two acknowledgements have a fourth value, andwherein the j is an imaginary unit.
