    • A method of reducing a retransmission of a data frame and a receiving node therefor continuously receiving N data frames generated by encoding K source data packets by erasure coding. Errors in the received N data frames are checked, and an ACK message transmitted informing that the source data packets are capable of being restored, when the number (R) of data frames not containing errors is equal to or greater than the number (K) of source data packets. An ACK message including the number (X) of data frames for which retransmission is to be requested is transmitted when the number (R) of data frames not containing errors is less than the number (K) of source data packets, as a result of checking for errors in the received N data frames. Despite errors in some of the data frames, data may be restored without requesting the retransmission of data frames.
    • 一种减少数据帧和其接收节点的重传的方法,通过擦除编码连续接收通过编码K个源数据分组而产生的N个数据帧。 检查所接收的N个数据帧中的错误,并且当不包含错误的数据帧的数量(R)等于或大于数量(K)时,发送通知源数据分组能够恢复的ACK消息, 的源数据包。 当不包含错误的数据帧的数量(R)小于源数据分组的数量(K)时,发送包括要请求重传的数据帧的数量(X)的ACK消息,作为 检查接收到的N个数据帧中的错误。 尽管在一些数据帧中存在错误,但是可以在不请求重发数据帧的情况下恢复数据。

    • There are provided a multi-relay transmission apparatus and method. The multi-relay transmission apparatus includes: a source node repeatedly alternately performing a first phase in which preceding data is transmitted during a first transmission period equivalent to a transmission period during which unit frames are transmitted and a second phase in which subsequent data that follows the preceding data is transmitted during a second transmission period that follows the first transmission period; and a relay network including a plurality of relay nodes receiving data from the source node, in which, in the first phase, a predetermined relay node, among the plurality of relay nodes, receives the preceding data from the source node and the remaining relay nodes, among the plurality of relay nodes, and in the second phase, the remaining relay nodes receive the subsequent data from the source node.
    • 提供了一种多中继传输装置和方法。 多中继传输装置包括:源节点重复地交替执行第一阶段,其中在与发送单元帧的传输周期相当的第一传输周期期间发送先前的数据,以及第二阶段,其中后续数据在 在第一传输周期之后的第二传输周期期间发送前一数据; 以及包括从所述源节点接收数据的多个中继节点的中继网络,其中,在所述第一阶段中,所述多个中继节点中的预定中继节点从所述源节点和所述剩余中继节点接收所述先前数据 在多个中继节点中,并且在第二阶段中,剩余的中继节点从源节点接收后续数据。
