Method and system of retransmission
First Claim
1. A method of reducing or eliminating transmissions over a scarce communication link resource in a communications system, whereina network element responsible for transmissions over the scarce communication link resource establishes an image of the scarce communication link resource receiving end status on the network element side of the scarce communication link resource, andupon reception of a request for a report on status of the receiving end of the scarce communication link resource destined for the receiving end of the scarce communication link resource, the network element identifies the request.

1. A method of reducing or eliminating transmissions over a scarce communication link resource in a communications system, wherein
a network element responsible for transmissions over the scarce communication link resource establishes an image of the scarce communication link resource receiving end status on the network element side of the scarce communication link resource, and upon reception of a request for a report on status of the receiving end of the scarce communication link resource destined for the receiving end of the scarce communication link resource, the network element identifies the request.
-
9. A method of reducing or eliminating transmissions over a scarce communication link resource in a communications system, wherein
a network element responsible for reception of transmissions over the scarce communication link resource establishes an image of the scarce communication link resource receiving end status on the network element side of the scarce communication link resource, and upon activation of a status report trigger of the network element, the network element transmits a report on status of the receiving end of the scarce communication link resource to a network control element.
-
15. A method of reducing or eliminating transmissions over a scarce communication link resource in a communications system, wherein
a network element for receiving signals in the form transmitted over the scarce communication link resource receives messages or status reports as transmitted over the scarce communication link resource, and determines whether the received message or status report, or parts thereof, should be processed in the network element, or if it should be forwarded.
-
20. A network element for transmitting signals over a scarce communication link resource in a communications system, comprising:
-
means for reducing or eliminating transmissions of messages or status reports over a scarce communication link resource in a communications system, means for establishing an image of the scarce communication link resource receiving end status, and means for identifying a request for a report on status of the receiving end of the scarce communication link resource destined for the receiving end of the scarce communication link resource. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A network element for transmitting signals over a scarce communication link resource in a communications system, comprising:
-
means for reducing or eliminating transmissions of messages or status reports over a scarce communication link resource in a communications system, means for establishing an image of the scarce communication link resource receiving end status, and means for transmitting a report on status of the receiving end of the scarce communication link resource. - View Dependent Claims (29)

30. A network element for receiving signals in the form transmitted over a scarce communication link resource, comprising:
-
means for reducing or eliminating transmissions over a scarce communication link resource in a communications system, means for receiving one or more messages or status reports in the form transmitted over the scarce communication link resource, and means for determining whether the received message or status report, or parts thereof, should be processed in the network element or if it should be forwarded.

-
31. A user equipment being responsible for transmitting signals over a scarce communication link resource in a communications system to one or more network elements, comprising:
-
electronic circuitry for providing at least one of the network elements with information enabling the at least one of the network elements to establish an image of the user equipment receive status, wherein the provision of the information is initiated in an entity including a protocol layer responsible for hybrid ARQ over the scarce communication link resource. - View Dependent Claims (32, 33)
