The user-centric ultra-dense networks (UUDNs) confront the challenge of performance degradation because of the erroneous user equipment (UE), and data base station (DBS) positions estimated at the central controller (CC). This paper adopts the database aided approach to quantify the error impact on system-level key performance indicators (KPIs) under various configuration and optimization parameters (COPs). Although the performance fall is consistent with the increase in error radius of both UEs and DBS positions, its impact can be alleviated by extrapolating on the erroneous database and adopting to new COP values. To realize this, time-series (TS) forecasting is utilized to determine the extent of compensation and COP variations. Results compared for two TS based schemes show that a significant portion, more than 50%, of the decreased performance can be recovered by the suggested adoption in the COP values.
