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, 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.
