Automatic request apparatus and method for multihop system in broadband wireless access communication network
摘要：
Provided are an ARQ apparatus and method for a multihop system in a broadband wireless access communication system. The ARQ method of a relay includes determining if the relay successfully receives specific data from a source and transmitting the specific data to a destination; receiving feedback data from the destination and determining if the destination successfully receives the specific data; generating feedback data including data indicating if the relay and the destination successfully receive the specific data, and outputting the feedback data to the source; and retransmitting the specific data, when the relay successfully receives the specific data but the destination fails to receive the specific data. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.
摘要（中）：

提供了一种用于宽带无线接入通信系统中的多跳系统的ARQ装置和方法。 继电器的ARQ方法包括确定中继器是否成功从源接收特定数据并将特定数据发送到目的地; 从目的地接收反馈数据并确定目的地是否成功接收到特定数据; 产生反馈数据，包括指示中继站和目的地是否成功接收到特定数据的数据，并将反馈数据输出到源; 并且当中继器成功接收到特定数据但是目的地不能接收到特定数据时，重发特定数据。 因此，当MH-BTS从源地成功接收到数据但目的地不能接收数据时，源不向MH-BTS发送相同的数据。
