Thank you for your replay.
These cells are as you mentioned,
intra-sector cells that use the same SC, so they belong to a sector with two carriers. Yes this is a standard configuration.
I don’t find any degradation in QoS or SHO success rate may be because the alarm is shone only for few seconds and the problem is not consistent all the time.
As i have mentioned i have checked the neighbors of neighbors for same
SC allocation but i couldn’t find any problem.
This situation seems very strange to me, i doubt that the triggered alarm is real.
