APPARATUS AND METHOD FOR TRANSMITTING CHANNEL QUALITY INDICATOR AND ACKNOWLEDGEMENT SIGNALS IN SC-FDMA COMMUNICATION SYSTEMS |
摘要 |
A method and apparatus for transmitting and receiving information symbols in a communication system are provided. A method includes determining a channel quality indicator (CQI); determining two acknowledgement bits in response to data reception; 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. 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. |

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; 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, 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. |
