Abstract  Abstract

A device and method for transmitting symbol group and an apparatus and method for receiving a symbol group. The invention distributing CDM segment of ACK/NACK signal is mapped in the frequency domain of an OFDM symbol and repeatedly transmits the CDM segment thereby providing diversity gain in the time-frequency domain. Further the present invention provides a mapping rule for distributing transmit power between OFDM symbols of the ACK/NACK signal is mapped and transmitted thereby preventing the case where a particular OFDM symbol is power-overloaded thus contributing to improvement of the entire system performance.
