Abstract
An apparatus and a method for sending a control information for retransmission in a multihop relay wireless communication system are provided. Data received from a lower node is checked for errors. The data is transmitted to an upper node, when the data has no errors. When two or more information, which include at least one of Acknowledgement (ACK) and Negative ACK (NACK) in response to a data reception are received from one or more lower nodes, the two or more information are transmitted to the upper node at the same time. Accordingly, the RS can transmit the control information for the ARQ provided from the lower nodes, to the upper node at the same time.
