First Claim
Patent Images
1. A method of retransmitting packet units in a communications system, said method comprising the steps of:
- providing a retransmission loop between a sending entity and a receiving entity, said retransmission loop including two or more concatenated retransmission sub-loops, comprising a first transmitter, a second transmitters, and a receiver; and
transferring signaling from the second transmitter to the first transmitter, the signaling carrying a status variable indicating a next in-sequence number of a packet unit expected to be acknowledged by the receiving entity, the signaling being transferred in association with handover.

23. A network element for retransmitting packet units in a communications system, said network element comprising:
-
a retransmission loop between a sender and a receiver, said retransmission loop comprising two or more concatenated retransmission sub-loops, the retransmission loop comprising;
a first transmitters;
a second transmitter; and
receive means for receiving signaling carrying a status variable from the second transmitter, the status variable indicating a next in-sequence number of a packet unit expected to be acknowledged by the receiver, the signaling being transferred in association with handover. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)

32. A network element for retransmitting packet units in a communications system, said network element comprising:
-
a retransmission loop between a sender and a receiver, said retransmission loop comprising two or more concatenated retransmission sub-loops, the retransmission loop comprising;
a first transmitter;
a second transmitter; and
transmit means for transferring signaling to the first transmitter, said signaling carrying a status variable indicating a next in-sequence number of a packet unit expected to be acknowledged by the receiver, the signaling being transferred in association with handover. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A receiving device for receiving transmissions and retransmissions of packet units on a communications channel in a communications system, wherein a retransmission loop between a sender and the receiving device includes two or more concatenated retransmission sub-loops, the receiving device comprising:
-
means for determining a receive status; and
transmit means for transferring one or more signals carrying the receive status to a network element, the one or more signals being transferred in association with handover. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58)
