Method and arrangement in a telecommunication system in which an acknowledgment message is fed back for a bundle of frames |
摘要 |
A method in a receiving node for sending an acknowledgement/not acknowledgement ACK/NACK feedback report of received data units over a radio link is provided. When the receiving node have received (301) data units in a number of subframes over a first radio link from a sending node, it creates (302) an ACK/NACK feedback report. The report is compressed such that it comprises one single ACK/NACK feedback relating to the data units in the number of received subframes, and the report comprises an indicator indicating said number of received subframes. The sending node then transmits (303) the created ACK/NACK feedback report to the sending node over a second radio link. The feedback report renders it feasible for the sending node to decide whether a retransmission of any subframe is required or not based on a comparison of the reported number of received subframes with the known transmitted number of subframes per frame, together with the compressed ACK/NACK feedback report. |
