Identify UE is in cell edge conditions

Hi team,

Using Wireshark I can see there is SNIR value as -17, in RACH messages.

So, can we say UE is in cell edge conditions, according to 3GPP?

SINR below -5 dB is considered extremely poor.
Never observed SINR to be below -7 dB even in edge condition.

Low sinr is due to strong interference.
Usually call drop at -7 dB.
Has nothing to do with rsrp or cell middle or cell edge.
It has to do with overlaping between cells, too many PCIs in one location and no dominance.

May be dlrsboost is 3 db. You can deboost it.

Make one dominant cell in that area with CIO.
