Abstract

One embodiment is a method and includes receiving at a termination element of a first network a bandwidth report (“BWR”), in which the BWR includes information regarding a data transmission opportunity over a second network for at least one endpoint data; scheduling a first network transmission opportunity for the at least one endpoint data using information derived from the received BWR; and receiving from a 5 first network forwarding device the at least one endpoint data in accordance with the scheduled first network transmission opportunity.

Claims (35)

1. A method comprising:

determining a failure corresponding to a packet;

setting, in response to determining the failure, each of a plurality of Bandwidth Reports (BWRs) assigned corresponding to remaining packets received subsequent to the packet corresponding to the failure in a predetermined amount of time in the future to zero;

determining that the packet has been successfully retransmitted;

providing, by an eNodeB (eNB), a BWR indicating grants sufficient to cover all received packets queued since determining the failure plus packets that are expected to egress the eNB in the predetermined amount of time in the future; and

queuing all the packets received subsequent to determining the failure, wherein queuing all the packets received subsequent to determining the failure comprises queuing all the packets received subsequent to determining the failure at a Radio Link Control (RLC) layer of the eNB.

2. The method of claim 1 , wherein the failure comprises the packet failing to be transmitted over an air interface between User Equipment (UE) and the eNB.

3. The method of claim 1 , wherein the failure comprises a Hybrid Automatic Repeat reQuest (HARQ) failure.

4. The method of claim 1 , wherein the predetermined amount of time in the future comprises at least 8 subframes.

5. The method of claim 1 , wherein providing the BWR comprises providing the BWR to a Cable Modem (CM).

6. The method of claim 1 , wherein determining that the packet has been successfully retransmitted comprises determining that the packet has been successfully retransmitted and has passed a HARQ checksum.

7. A system comprising:

a memory storage; and

a processing unit coupled to the memory storage, wherein the processing unit is operative to:

determine a failure corresponding to a packet;

set, in response to determining the failure, each of a plurality of Bandwidth Reports (BWRs) assigned corresponding to remaining packets received subsequent to the packet corresponding to the failure in a predetermined amount of time in the future to zero;

determine that the packet has been successfully retransmitted;

provide a BWR indicating grants sufficient to cover all received packets queued since determining the failure plus packets that are expected to egress an eNB a predetermined amount of time in the future; and

queue all the packets received subsequent to determining the failure, wherein queuing all the packets received subsequent to determining the failure comprises queuing all the packets received subsequent to determining the failure at a Radio Link Control (RLC) layer of the eNB.

8. The system of claim 7 , wherein the failure comprises the packet failing to be transmitted over an air interface between User Equipment (UE) and the eNB.

9. The system of claim 7 , wherein the failure comprises a Hybrid Automatic Repeat reQuest (HARQ) failure.

10. The system of claim 7 , wherein the predetermined amount of time in the future comprises at least 8 subframes.

11. The system of claim 7 , wherein the processing unit being operative to provide the BWR comprises the processing unit being operative to provide the BWR to a Cable Modem (CM).

12. The system of claim 7 , wherein the processing unit being operative to determine that the packet has been successfully retransmitted comprises the processing unit being operative to determine that the packet has been successfully retransmitted and has passed a HARQ checksum.

13. A computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:

determining a failure corresponding to a packet;

setting, in response to determining the failure, each of a plurality of Bandwidth Reports (BWRs) assigned corresponding to remaining packets received subsequent to the packet corresponding to the failure in a predetermined amount of time in the future to zero;

determining that the packet has been successfully retransmitted;

providing, by an eNB, a BWR indicating grants sufficient to cover all received packets queued since determining the failure plus packets that are expected to egress the eNB a predetermined amount of time in the future; and

queuing all the packets received subsequent to determining the failure, wherein queuing all the packets received subsequent to determining the failure comprises queuing all the packets received subsequent to determining the failure at a Radio Link Control (RLC) layer of the eNB.

14. The computer-readable medium of claim 13 , wherein the failure comprises the packet failing to be transmitted over an air interface between User Equipment (UE) and the eNB.

15. The computer-readable medium of claim 13 , wherein the failure comprises a Hybrid Automatic Repeat reQuest (HARQ) failure.

16. The computer-readable medium of claim 13 , wherein the predetermined amount of time in the future comprises at least 8 subframes.

17. The computer-readable medium of claim 13 , wherein providing the BWR comprises providing the BWR to a Cable Modem (CM).

18. The computer-readable medium of claim 13 , wherein determining that the packet has been successfully retransmitted comprises determining that the packet has been successfully retransmitted and has passed a HARQ checksum.
