Summary

The objective of this working is to find out overshooting cells that may cause pilot pollution and

degrade quality.

Following inputs were used for identification of such cases

Pilot Pollution output generated by XEUS tools based on Huawei PCHR data.

RSCP plots from recently conducted extensive drive test activity.

Best RSCP plot from XEUS tool based on PCHR data (where required).

TP distribution stats from M2000.

In this working, only the overshooting cells which have acceptable coverage in their serving area

have been targeted.

RF footprint of the identified cells needs to be contained by down-tilting.
