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

1. A method comprising:

determining a failure corresponding to a packet;

setting, in response to determining the failure, Bandwidth Reports (BWRs) subsequent to the failure to zero;

determining that the packet has been successfully retransmitted; and

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.

2. The method of claim 1, further comprising queuing all the packets received subsequent to determining the failure.

3. The method of claim 2, wherein queuing all the packets received subsequent to determining the failure comprises queuing all the packets received subsequent to determining the failure at an Radio Link Control (RLC) layer of the eNB.

4. 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.

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

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

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

8. 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.

9. A method comprising:

creating a plurality of Data Over Cable Service Interface Specification (DOCSIS) service flows;

mapping, respectively and correspondingly, a plurality of logical channel groups (LCGs) to the plurality of DOCSIS service flows to create a plurality of LCG and SF pairs; and

providing quality of service (QoS) levels congruent with each of the plurality of LCGs to their respective corresponding ones of the plurality of DOCSIS service flows.

10. The method of claim 9, further comprising providing a Bandwidth Report (BWR) with a number of entries equal to the number of LCG and SF pairs in the plurality of LCG and SF pairs.

11. The method of claim 9, wherein mapping the plurality of LCGs to the plurality of DOCSIS service flows comprises mapping same Evolved Packet System (EPS) bearers to each of the plurality of LCG and SF pairs.

12. The method of claim 9, wherein the QoS levels comprise the following:

Best Effort (BE);

Real-Time Polling Service (RTPS); and

Unsolicited Grant Service (UGS).

13. The method of claim 9, wherein the plurality of DOCSIS service flows respectively correspond to a plurality of DOCSIS service flow queues on a Cable Modem (CM).

14. The method of claim 9, wherein the a plurality of LCGs respectively correspond to a plurality of LCG queues on an eNB.

15. A method comprising:

receiving a Bandwidth Report (BWR);

determining that a number bytes requested by a device is greater than a number of bytes requested by the BWR;

indicating an error signal in response to determining that the number bytes requested by the device is greater than the number of bytes requested by the BWR; and

altering a granting scheme based on the error signal.

16. The method of claim 15, wherein receiving the BWR comprises receiving the BWR from a Long Term Evolution (LTE) scheduler in an eNB.

17. The method of claim 15, wherein receiving the BWR comprises receiving the BWR wherein the number of bytes requested by the BWR represents an intended future flow of bytes over time across a network interface between the device and an eNB.

18. The method of claim 15, wherein altering the granting scheme based on the error signal comprises over-granting.

19. The method of claim 15, wherein altering the granting scheme based on the error signal comprises under-granting.

20. The method of claim 15, wherein the device comprises a Cable Modem (CM).
