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.

determining that the resources available to wireless base station for transmitting data from the wireless base station to the communication node upstream of the wireless base station are sufficient to accommodate all of the first uplink data and all of the second uplink data;
in response to determining that the resources available to wireless base station for transmitting data from the wireless base station to the communication node upstream of the wireless base station are sufficient to accommodate all of the first uplink data and all of the second uplink data, grouping all of the first uplink data and all of the second uplink data into a combined package of data; and
sending the combined package of data from the wireless base station to the communication node upstream of the wireless base station.
13. The method of claim 12 , wherein the first uplink data includes at least a first subset of the first uplink data and a second subset of the first uplink data, the first subset of the first uplink data having a higher priority than the second subset of the first uplink data.
14. The method of claim 12 , further comprising, sending, from the wireless access point to the communication node upstream of wireless base station, a bulk request for sufficient resources for transmitting at least the first uplink data and the second uplink data from the wireless base station to the communication node upstream of wireless base station.
