RRC Connection Failure in QXDM?

 RRC Connection Setup Complete is missing, the UE cannot attach.

Possible reasons:

·         Weak RSRP/RSRQ → Low signal strength.

·         Interference → Neighbouring cell interference.

·         Congestion → Too many users causing RRC setup failure.

Debugging in QXDM

• Check 0xB889 (Serving Cell RSRP/RSRQ) to confirm signal quality.
• Look at 0xB883 (RRC Connection Setup Failure) logs for failure reasons.
