Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a device and a method for transmitting and receiving positive acknowledgement/negative acknowledgement (ACK/NACK) signals to a hybrid automatic retransmission request (HARQ) in a mobile communication system.

SOLUTION: A symbol group transmission method in the mobile communication system includes the steps of: generating a symbol group to which an orthogonal sequence is applied; on the basis of a symbol group index and a PHICH (Physical HARQ Indicator Channel) group index mapping the generated symbol group to an OFDM (Orthogonal Frequency Division Multiple) symbol; and transmitting the mapped symbol group. The generated symbol group is mapped to the OFDM symbol to have an alternate pattern by the symbol group index.
