Abstract
A method is provides in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes (401) that a number of data units that has been transmitted by the sending node are missing. The receiving node sends (402) a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.

Claim
1. A method in a receiving node for handling status information of data units or data unit segments further on referred to as "data units" transmitted from a sending node to the receiving node over a radio link, the method comprising the steps of: establishing that a number of data units that has been transmitted by the sending node are missing, sending a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units, wherein the reduced status message positive acknowledges data units up to but not including the first missing data unit for which a negative acknowledgement was omitted in the reduced status message such that the omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node, wherein the positive acknowledgement is performed by setting an ACK_SN field to the first missing data unit for which a negative acknowledgement was omitted in the reduced status message, meaning that data units with sequence numbers up to but not including the first missing data unit for which a negative acknowledgement was omitted, are acknowledged, and wherein the ACK_SN field is a part of the reduced status message.
2. Method according to claim 1 , wherein the negative acknowledgement for the first part of missing data units comprised in the reduced status message is represented by as many negative acknowledgements as fitted in the reduced status message because of limited resources.
3. Method according to any of the claims 1 -2, wherein the receiving node uses a receiving window and wherein the negative acknowledgement for the fist part of the missing data units, are the missing data units which are closest to a lower edge of the receiving window.
4. A method in a sending node for handling status information of data units or data unit segments further on referred to as "data units" transmitted from the sending node to the receiving node over a radio link, the method comprising the steps of: transmitting a stream of data units, over the radio link to the receiving node, wherein the receiving node correctly receives some of the transmitted data units but misses a number of the transmitted data units, and receiving a reduced status message from the receiving node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgement for the rest of the missing data units, wherein the reduced status message positive acknowledges data units up to but not including the data unit for which a negative acknowledgement was omitted in the reduced status message, such that the omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node, and wherein the positive acknowledgement is performed by setting an ACK_SN field to the first missing data unit for which a negative acknowledgement was omitted in the reduced status message, meaning that data units with sequence numbers up to but not including the first missing data unit for which a negative acknowledgement was omitted, are acknowledged, and wherein the ACK_SN field is a part of the reduced status message.
5. Method according to claim 4, wherein the negative acknowledgement for the first part of missing data units comprised in the reduced status message is represented by as many negative acknowledgements as fitted in the reduced status message because of limited resources.
6. Method according to any of the claims 4-5 wherein the negative acknowledgement for the fist part of missing data units are the missing data units which are closest to a lower edge of a receiving window in the receiving node.
7. Method according to any of the claims 4-6, wherein the sending node uses a transmission window, comprising the further step of: moving a lower edge of the transmission window up to the lowest negatively acknowledged data unit.
8. An arrangement in a in a receiving node for handling status information of data units or data unit segments further on referred to as "data units", transmitted from a sending node to the receiving node over a radio link, the receiving node arrangement comprising: an establishing unit configured to establish that a number of data units that has been transmitted by the sending node are missing, and a sending unit configured to send a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units, wherein the reduced status message positive acknowledges data units up to but not including the first missing data unit for which a negative acknowledgement was omitted in the reduced status, message such that the omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node, and wherein the positive acknowledgement is performed by setting a ACK_SN field to the first missing data unit for which a negative acknowledgement was omitted in the reduced status message, meaning that data units with sequence numbers up to but not including the first missing data unit for which a negative acknowledgement was omitted, are acknowledged, and wherein the ACK_SN field is a part of the reduced status message.
9. An arrangement in a sending node for handling status information of data units or data unit segments further on referred to as "data units", transmitted from the sending node to the receiving node over a radio link, sending node arrangement comprising: a sending unit configured to transmit a stream of data units, over the radio link to the receiving node, wherein the receiving node correctly receives some of the transmitted data units but misses a number of the transmitted data units, and a receiving unit configured to receive a reduced status message from the receiving node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgement for the rest of the missing data units, wherein the reduced status message positive acknowledges data units up to but not including the data unit for which a negative acknowledgement was omitted in the reduced status message, such that the omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node, and wherein the positive acknowledgement is performed by setting a ACK_SN field to the first missing data unit for which a negative acknowledgement was omitted in the reduced status message, meaning that data units with sequence numbers up to but not including the first missing data unit for which a negative acknowledgement was omitted, are acknowledged, and wherein the ACK_SN field is a part of the reduced status message.
