Hi MKT,
Well definitely reducing power to avoid overshooting is not a preferable solution to the problem.
A step-wise approach need to be adapted to overcome this problem.
1. A slight tilt needs to be given to the RF antenna.
2. Thorough drives to be done at the cell coverage, especially at the border areas and check for interference.
3. If still problem exists and no further tilt can be given, then power optimization comes to picture.
