There is provided a method, performed by a receiving node, for generating composite acknowledgement information for a Hybrid Automatic Repeat Request, HARQ, process. The composite acknowledgement information is generated in response to transport blocks received from a transmitting node. The method comprises the step (301) of providing, for each transport block, a positive acknowledgement/negative acknowledgement, ACK/NAK, indication for each of a plurality of transmissions of the transport block to define a respective set of ACK/NAK indications. The method also comprises the step (302) of generating the composite acknowledgement information based on the respective sets of ACK/NAK indications for the transport blocks over the plurality of transmissions. In this way, by considering respective sets of ACK/NACK indications over a plurality of transmissions, it is possible to generate an appropriate composite acknowledgment. A direct consequence of the proposed technology is that the composite acknowledgement information is generated as a positive acknowledgment, ACK, if two transport blocks have been successfully received even though the two transport blocks do not belong to the same transmission. |
