1. A radio head for a backhaul system in operable communication with a user equipment device (UE) separate from the radio head and configured to transmit a buffer status report (BSR) to the radio head, the radio head comprising:
a small cell configured to (i) receive a plurality of IP packets from the UE over a series of consecutive sequential sub-frames, and (ii) generate a bandwidth report (BWR) for each of the plurality of received IP packets, wherein the BWR generated by the small cell is different from the BSR transmitted from the UE;
a control unit configured to, for each of the plurality of received IP packets, (i) receive the respective generated BWR, and (ii) sum the received BWR with a segmentation induced noise value; and
an adaptive filter configured to, for each sub-frame pair including a first sub-frame preceding a consecutive second sub-frame in time in the series of consecutive sequential sub-frames, apply a filter weight to the second sub-frame based on an output of the (i) control unit for the first sub-frame, and (ii) adaptive filter for the first sub-frame.
