Appratus and method for retransmission in wireless communication systems

The present invention relates to a retransmission apparatus and method for a wireless communication system, in the case of fixedly allocated resources to the terminal, the control message by using the fixed allocated resources and transmitting data to the terminal, receiving from the terminal a case wherein the transmission procedure to determine error occurrence in the data and, where the error occurred in the data through the process and, a resource information allocated for the retransmission allocating resources for re-transmitting the data that the failed It may be, including the step of retransmitting the data that the error has occurred, using a resource allocated for the process and the retransmission of transmitting to the mobile station to the mobile station to clearly recognize the original packet information for the retransmission packet to reduce the retransmission error .
