1. A method for use in a packet-switched communication system, the method comprising:
- sending a first packet from a source node to a destination node, the first packet containing a first set of data bits; and
sending a second packet from the source node to the destination node, the second packet containing a second set of data bits;
wherein, in the event that the first set of data bits cannot be successfully decoded in the destination node, the second packet further comprises a first set of error correction bits for the first set of data bits.

12. A source node for use in a packet-switched communication system, the source node comprising:
-
means for sending data packets to a destination node, each data packet comprising a respective set of data bits; and means for receiving an acknowledgement from the destination node for each data packet indicating whether each data packet has been successfully decoded in the destination node; wherein, in the event that the acknowledgement indicates that a data packet cannot be successfully decoded in the destination node, the means for sending is further adapted to send, with the next data packet that comprises a respective set of data bits, a set of error correction bits for the data bits in the data packet that contains errors.

13. A destination node for use in a packet-switched communication system, the destination node comprising:
-
means for receiving data packets from a source node, each data packet comprising a respective set of data bits; and means for determining if each received data packet can be successfully decoded by the destination node; wherein, in the event that a data packet cannot be successfully decoded by the destination node, the means for receiving is further adapted to receive, with the next data packet that comprises a respective set of data bits, a set of error correction bits for the data bits in the packet that contains errors.

14. A packet-switched communication system comprising a source node and a destination node, the destination node comprising means for receiving data packets from the source node, each data packet comprising a respective set of data bits, and means for determining if each received data packet can be successfully decoded by the destination node, wherein if a data packet cannot be successfully decoded by the destination node, the means for receiving is further adapted to receive, with the next data packet that comprises a respective set of data bits, a set of error correction bits for the data bits in the packet that contains errors.

15. A packet-switched communication system comprising a source node and a destination node, the source node including means for sending data packets to a destination node, each data packet comprising a respective set of data bits, and means for receiving an acknowledgement from the destination node for each data packet indicating whether each data packet has been successfully decoded in the destination node, wherein if the acknowledgement indicates that a data packet cannot be successfully decoded in the destination node, the means for sending is further adapted to send, with the next data packet that comprises a respective set of data bits, a set of error correction bits for the data bits in the data packet that contains errors.
