Hi @Anuj_Gupta.
Need to check cause for RACH failure.
Is it contention resolution failure or msg3 getting failed due to crc NOK?
Few remedy from network end:
- Check for radio conditions, i.e. pathloss should not be high.
- Check for PRACH format used.
- Distance from ue accessing the cell.
- RSI planning to be proper to avoid conflict.
- Parameter preamble power rampup, retry for RACH should be inline with golden values.
