I need what the reason for RACH attempt failure?

2

• PRACH root sequence clashes
• Antenna radiating beyond cell range
• PDCCH congestion & Coverage issue

3

RSI collision
You can check cell range(zero correlation value)
Coverage holes
These are the first three things along with you can check overshooting cases as well….

4

Any parameter to check in RACH configuration?
There are 4 message in RACH procedure for each message what are the related parameters?
