Abstract  Abstract

A method and apparatus are provided for transmitting one or more positive or negative acknowledgement (ACK/NACK) bits in response to data reception in a single-carrier frequency division multiple access (SC-FDMA) communication system. The method includes if the one or more ACK/NACK bits are one bit applying a first code to a first symbol if the acknowledgement bit is NACK and applying a second code to the first symbol if the acknowledgement bit is ACK; if the one or more ACK/NACK bits are two bits applying quadrature phase shift keying (QPSK) modulation to the first symbol based on a value of the two ACK/NACK bits; if no ACK/NACK bit exists applying the first code to the first symbol; and transmitting the first symbol and a second symbol in a slot.
