Summary:A method and arrangement for retransmission control. A method in a sending system entity for controlling retransmissions of data to a sending system entity is provided. Initial data encoded with a first forward error correction code is sent 200 to the receiving system entity. When transmitted initial data is determined to be affected by errors at the receiving system entity, the sending system entity receives 202 a request to retransmit the initial data combined 204 by new data encoded with a second forward error correction code in a combined data stream which is encoded 206 with a third forward error correction code before being sent 208 to the receiving system entity. By combining initial data and encoded new data in a combined data stream when resending, an effective and flexible procedure for retransmissions is achieved, which doesn't introduce any substantial delay of the data.
