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

  • determining a channel quality indicator (CQI);

    determining two acknowledgement bits in response to data reception, the two acknowledgement bits representing two acknowledgements;

    generating a first symbol based on the CQI;

    generating a second symbol based on the two acknowledgement bits; and

    transmitting the first symbol and the second symbol in a slot,wherein a first code is applied to the second symbol, if the two acknowledgement bits have a first value, a second code is applied to the second symbol, if the two acknowledgement bits have a second value, a third code is applied to the second symbol, if the two acknowledgement bits have a third value, and a fourth code is applied to the second symbol, if the two acknowledgement bits have a fourth value.
