Abstract

A system and method for providing an MAP for an unsolicited grant to a modem in a wireless backhaul environment based on centralized small cell (cSC) data received at a modem termination system (MTS) is described herein.

First claim

What is claimed is:

1. A method for providing an unsolicited grant to a modem for the immediate transmission of a remote Small Cell (rSC) associated User Equipment (UE) data through a network, comprising:
receiving central Small Cell (cSC) generated uplink (UL) grant data at a modem termination system (MTS) related to a buffer status report (BSR) transmitted from the rSC to a cSC;
processing the received UL grant data in an unsolicited grant generation component;
generating an unsolicited grant as a function of the received UL grant data; and
transmitting the unsolicited grant to the modem in preparation for receipt of UL data related to the BSR and the UL grant data.

2. The method of claim 1 , wherein the network is a fronthaul network comprising the modem and the MTS.

3. The method of claim 2 , further comprising a remote physical (PHY) device (RPD).

4. The method of claim 2 , wherein the modem is a cable modem and the MTS is a cable modem termination system (CMTS).

5. The method of claim 1 , wherein the modem is selected from the group consisting of a satellite modem, an Optical Network Units (ONU), and a Digital Subscriber Line (DSL) unit.

6. The method of claim 1 , wherein the MTS is selected from a group consisting of an Optical Network Terminal (ONT), an Optical Line Termination (OLT), and a Cable Modem Termination System (CMTS).

7. The method of claim 1 , wherein the network utilizes a communication protocol selected from the group consisting of Data Over Cable Service Interface Specification (DOCSIS), Ethernet Passive Optical Network (EPON), Radio Frequency over Glass (RFOG), Gigabit Passive Optical Network (GPON), Digital Subscriber Line (DSL), and Satellite Internet Protocol.

8. The method of claim 1 , wherein the received UL grant data is transmitted from the cSC as an UL grant for the rSC.

9. The method of claim 8 , further comprising intercepting, by the MTS, the UL grant transmitted from the cSC to the rSC for processing by the unsolicited grant generation component.

10. The method of claim 1 , wherein the received UL grant data is transmitted from a centralized small cell (cSC) to the MTS as an UL grant summary for processing by the unsolicited grant generation component.

11. The method of claim 1 , where the received UL grant data is transmitted from the rSC to the cSC as the BSR.

12. The method of claim 11 , further comprising intercepting, by the MTS, the BSR transmitted from the rSC to the cSC for processing by the unsolicited grant generation component.

13. The method of claim 1 , wherein the network is a fronthaul network.

14. The method of claim 1 , wherein the MTS is a virtualized MTS (vMTS) in cooperative communication with a Remote PHY Device (RPD).

15. A latency reduction system in an fronthaul environment for fronthauling small cell data, comprising:
a modem termination system (MTS) comprising,
an uplink (UL) grant data receiving unit configured to receive central Small Cell (cSC) generated UL grant data associated with a remote Small Cell (rSC) buffer status report (BSR); and
a unsolicited grant generation processing unit configured to process the UL grant data to generate an unsolicited grant for transmission to a modem;

wherein the unsolicited grant is for a modem in communication with the MTS in preparation for a UL data associated with the UL grant data such that the UL data may be immediately transmitted to the cSC via the modem and MTS.

16. The system of claim 15 , wherein the MTS is a virtualized MTS (vMTS) in cooperative communication with a Remote Physical (PHY) Device (RPD).

17. The system of claim 15 , wherein the UL grant data receiving unit intercepts a BSR sent from the rSC to the cSC for processing by the unsolicited grant generation processing unit.

18. The system of claim 15 , wherein the UL grant data receiving unit receives a UL grant summary sent from the cSC to the MTS for processing by the unsolicited grant generation processing unit.

19. The system of claim 15 , wherein the UL grant data receiving unit intercepts a UL grant sent from the cSC to the rSC for processing by the unsolicited grant generation processing unit.

20. The system of claim 15 , wherein the fronthaul environment utilizes a communication protocol selected from the group consisting of Data Over Cable Service Interface Specification (DOCSIS), Ethernet Passive Optical Network (EPON), Radio Frequency over Glass (RFOG), Gigabit Passive Optical Network (GPON), Digital Subscriber Line (DSL), and Satellite Internet Protocol.
