Controlling apparatus of hybrid auto repeat request in mobile communication system

The present invention relates to a HARQ controller device and a control method in a mobile communication system performing HARQ. Accordingly, the present invention is to reduce the load on the CPU in an HARQ control apparatus, and this power consumption in the terminal via, to provide an apparatus and method for reducing the load on the CPU caused by a maximum driving clock. In addition, reduce the data processing time in an HARQ control apparatus, there is provided a compound N-channel if it supports the Simple Retransmission control device that is independent on the number of channels and its control method. HARQ (HARQ), a state transition, fast HARQ control
