Abstract  Abstract

The present invention provides an apparatus and method for transmitting / receiving an ACK / NACK (Acknowledge / Negative Acknowledge) signal supporting a Hybrid Automatic Repeat Request (HARQ) in a mobile communication system.
The present invention provides a diversity gain in a frequency domain and a time domain by repeatedly transmitting CDM segments to which ACK / NACK signals are mapped by dispersing them in a frequency domain of an OFDM symbol. Also, the present invention provides a mapping rule for distributing transmission power between OFDM symbols to which the ACK / NACK signal is mapped and transmitted, thereby preventing a case where a power overload occurs in a specific OFDM symbol in advance, It offers the advantage of improving performance.

ACK / NACK, HARQ, PHICH (Physical HARQ Indicator channel), Spreading Factor (SF), Repetition pattern
