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 in a communication network, comprising:
receiving a first uplink grant at the MTS from a central Small Cell (cSC);
sending the first uplink grant from the MTS to User Equipment (UE) downstream of the MTS;
generating an unsolicited grant, different from the first uplink grant; and
sending the unsolicited grant to a modem downstream of the MTS.
2. The method of claim 1 , wherein the communication network is a fronthaul network comprising a remote Small Cell (rSC) and the cSC.
3. The method of claim 1 , wherein the communication network further comprises a Remote Physical (PHY) device (RPD).
4. The method of claim 1 , wherein the modem downstream of the MTS is a cable modem and the MTS is a cable modem termination system (CMTS).
5. The method of claim 1 , wherein the modem downstream of the MTS is a cable modem and the MTS is another cable modem, which is in communication with a Cable Modem Termination System (CMTS).
6. The method of claim 1 , wherein the modem downstream of the MTS 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 , further comprising generating the unsolicited grant based on the first uplink grant received from the cSC.
10. The method of claim 1 , further comprising generating the unsolicited grant based on an UL grant summary received at the MTS from the cSC.
11. The method of claim 1 , further comprising generating the unsolicited grant based on a buffer status report (BSR) from the UE.
12. The method of claim 1 , wherein the communication network is a fronthaul network.
13. The method of claim 1 , wherein the MTS is a virtualized MTS (vMTS) in cooperative communication with a Remote Physical (PHY) Device (RPD).
14. A method for operating a central Small Cell (cSC) to reduce latency in a communication network, comprising:
receiving a buffer status report (BSR) generated by User Equipment (UE);
processing the BSR to generate a first grant;
processing the BSR to generate an uplink grant summary different from the first grant;
sending the first grant from the cSC to a modem termination system (MTS); and
sending the uplink grant summary from the cSC to the MTS.
15. The method of claim 14 , wherein the MTS is a virtualized MTS (vMTS) in cooperative communication with a Remote Physical (PHY) Device (RPD).
16. The method of claim 14 , 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.
