How to allocate frequencies in a wireless communication system that operates in the frequency hopping mode and a device therefor

A frequency allocation method in a wireless communication system that operates in the frequency hopping mode, and relates to a device therefor, mirroring (Mirroring) generating a mirror pattern by setting the frequency hopping cycle to a predetermined sub-frame unit by, when the data retransmission wherein performing frequency hopping according to the mirroring pattern, characterized by including the step of assigning a retransmission signal to the frequency domain and different frequency-domain initial transmission. In addition, the frequency hopping cycle by the mirrors is characterized in that it is shorter than the data retransmission cycle. According to the frequency allocation method in a wireless communication system that operates in the frequency hopping mode of the present invention and an apparatus therefor, it is possible to ensure a frequency diversity gain by the mirror when HARQ.
