Systems and methods for latency reduction
Systems and methods presented herein provide for reducing latency in wireless service through a communication link comprising a Modem Termination System (MTS) and a modem. The communication link is coupled with a virtualized wireless link. In one embodiment, a method includes transferring a buffer status report (BSR) from a user equipment (UE) through the communication link to a control portion of the virtualized wireless link, generating a wireless grant to allow the data of the UE through virtualized wireless link, and generating a backhaul grant for the UE to transfer data through the communication link based on the wireless grant information.
1. A system for reducing latency in wireless service through a communication link, the system comprising:
a. a Modem Termination System (MTS) and a modem operable as the communication link in communication with a virtualized wireless link;
b. wherein the virtualized wireless link is operable to transfer a buffer status report (BSR) from a user equipment (UE) through the communication link to a control portion of the virtualized wireless link, and to generate a wireless grant to allow the data of the UE through virtualized wireless link,
c. wherein the MTS is operable to generate a backhaul grant for the UE to transfer data through the communication link in response to the BSR.
2. The system of claim 1 , wherein:
a. the virtualized wireless link is further operable to transfer a plurality of BSRs from a plurality of UEs through the communication link to the control portion of the virtualized wireless link, and to generate a plurality of wireless grants to allow the data of the plurality of UEs through virtualized wireless link; and
b. the MTS is further operable to generate a plurality of backhaul grants to transfer data through the communication link in response to the plurality of BSRs.
3. The system of claim 2 , wherein:
a. the virtualized wireless link is further operable to prioritize the plurality of wireless grants before transfer to the plurality of UEs.
4. The system of claim 2 , wherein:
a. the virtualized wireless link is further operable to generate the plurality of wireless grants according to one or more of the following protocols: Long Term Evolution (LTE) and WiFi.
5. The system of claim 2 , wherein:
a. the virtualized wireless link is further operable to extract data transfer sizes, data transfer times, and priorities of the data being transferred by the plurality of UEs from the plurality of BSRs, and to configure a data size of the grants, a timing of the grants, and a priority of the grants from the MTS to the modem based on the extracted data transfer sizes, data transfer times, and priorities.
6. The system of claim 5 , wherein:
a. the virtualized wireless link is further operable to transfer the data from the plurality of UEs through the communication link based on the extracted priorities.
7. The system of claim 1 , wherein:
a. the MTS is operable to virtualize the wireless link by configuring Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) functionality of a small cell with the MTS.
