    摘要: Data retransmission apparatus and method in a wireless relay communication system are provided. It is checked whether an Acknowledgement (ACK) message or a Negative ACK (NACK) message for data is received from a Relay Station (RS), which receives the data from a Mobile Station (MS). Scheduling information for transmitting the data is transmitted to the RS, when the ACK message is received from the RS. Errors are checked for in of the data, when the data is received from the RS. The RS is requested to retransmit the data, when the data has an error. Accordingly, since the RS retransmits only the error-free data to the BS, the BS can enhance the data reliability.

    摘要: An apparatus and a method for sending a control message 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 messages, which include at least one of Acknowledgement (ACK) messages and Negative ACK (NACK) messages in response to a data reception are received from one or more lower nodes, the two or more messages are transmitted to the upper node at the same time. Accordingly, the RS can transmit the control messages for the ARQ provided from the lower nodes, to the upper node at the same time.
