    摘要: The invention concerns a data packet retransmission arrangement having a retransmission buffer, a counter, a forward error correction device and control logic. The retransmission buffer stores recently transmitted data packets. The counter keeps track of the number of retransmission requests received for a data packet (211). If this number is below a first integer value K, the data packet is retransmitted (212, 213). If this number is equal to or above the first integer value K, the forward error correction device calculates N forward error correction packets on L-1 recently transmitted data packets plus the data packet to be retransmitted (211), N being a second integer value equal to or larger than zero, and L being a third integer value equal to or larger than 1. In the latter case, the data packet is retransmitted together with the N forward error correction packets (214).
