A method of signaling which data blocks can be combined together in an incremental redundancy communication system includes a transmitter device and a receiver device. The method includes transmitting the blocks from a transmitter device to a receiver device. Each transmitted data block includes an information indicating whether a respective data block is transmitted for a first time or is a retransmitted block. At the receiver device, a check is made to see whether the transmission of a respective data block has failed. If the transmission of said respective block has failed, retransmission is made. In response to receiving the retransmission request at the transmitter device side, the information is set to a value indicating that the respective data block is a retransmitted block. A header is added to the data block to be retransmitted, the header representing a reference to a physical location of an earlier transmission of said block in a sequence of transmitted blocks. |
