System and method for grant assignment
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.
1. A method for operating a modem termination system (MTS) to reduce latency of wireless communication backhaul in a communication network including (i) the MTS and (ii) a central Small Cell (cSC) that is upstream of the MTS, the method comprising:
receiving, at the MTS, a wireless communication that is generated by user equipment (UE) and is directed to the cSC that is upstream of the MTS;
generating an unsolicited grant in response to receiving the wireless communication that is generated by the UE and is directed to the cSC that is upstream of the MTS; and
sending the unsolicited grant downstream of the MTS.
2. The method of claim 1 , wherein the communication network further includes a remote Small Cell (rSC).
3. The method of claim 1 , wherein the communication network further includes a Remote Physical (PHY) device (RPD).
4. The method of claim 1 , wherein sending the unsolicited grant downstream of the MTS comprises sending the unsolicited grant to a cable modem downstream of the MTS, the MTS being a cable modem termination system (CMTS).
5. The method of claim 1 , wherein sending the unsolicited grant downstream of the MTS comprises sending the unsolicited grant to a cable modem downstream of the MTS, the MTS being another cable modem which is in communication with a Cable Modem Termination System (CMTS).
6. The method of claim 1 , wherein sending the unsolicited grant downstream of the MTS comprises sending the unsolicited grant to a modem downstream of the MTS, wherein the modem is selected from the group consisting of a satellite modem, an Optical Network Unit (ONU), and a Digital Subscriber Line (DSL) unit.
7. 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).
8. The method of claim 1 , wherein the communication network utilizes a communication protocol selected from the group consisting of a Data Over Cable Service Interface Specification (DOCSIS) protocol, an Ethernet Passive Optical Network (EPON) protocol, a Radio Frequency over Glass (RFOG) protocol, a Gigabit Passive Optical Network (GPON) protocol, a Digital Subscriber Line (DSL) protocol, and a Satellite Internet protocol.
9. The method of claim 1 , wherein the communication network is a fronthaul network.
10. The method of claim 1 , wherein the MTS is a virtualized MTS (vMTS) in cooperative communication with a Remote Physical (PHY) Device (RPD).
11. The method of claim 1 , further comprising:
receiving, at the MTS, a first grant from upstream of the MTS; and
sending the first grant downstream of the MTS.
12. The method of claim 11 , wherein the first grant is generated by a wireless communication element.
13. The method of claim 12 , wherein the wireless communication element comprises the cSC that is upstream of the MTS.
14. The method of claim 1 , where the wireless communication that is generated by the UE and is directed to the cSC that is upstream of the MTS comprises a buffer status report (BSR).
15. The method of claim 1 , further comprising receiving the wireless communication that is generated by the UE and is directed to the cSC that is upstream of the MTS via a wireless communication element.
16. The method of claim 15 , wherein the wireless communication element is a remote Small Cell (rSC).
