摘要： 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.
