5G RRC Procedures
5G RRC procedures control the radio connection between the UE and NG-RAN, from setup and reconfiguration through release, resume, measurements, paging, handover triggers, and recovery. Use this hub to jump into RRC setup, reconfiguration, reestablishment, release, resume, suspend, measurement reporting, conditional handover, paging, beam failure recovery, and radio link failure recovery call flows.

What This Covers
5G RRC setup, reconfiguration, release, suspend, and resume procedures manage the UE radio-control connection and state changes.
Measurement, paging, conditional handover, beam failure recovery, and radio link failure recovery flows support mobility and radio robustness.
Use the links below to jump directly into RRC setup, reconfiguration, recovery, release, resume, paging, measurement, and handover-related call flows.
Connection Entry and State Change
Procedures that create, release, suspend, or resume the dedicated 5G radio-control connection.
- RRC Setup — UE establishes radio connection
- RRC Release — Connection released
- RRC Suspend — Enter suspended state
- RRC Resume — Resume from idle
Radio Reconfiguration and Recovery
Procedures that update NR radio behavior or recover from radio-side failures and disruptions.
- RRC Reconfiguration — Radio parameters updated
- RRC Reestablishment — Recover connection after radio failure
- Beam Failure Recovery — Recover from beam-level radio disruption
- Radio Link Failure Recovery — Recover after radio link failure
Measurements and Mobility Triggers
Procedures that feed mobility decisions or pre-arm radio-control actions using measurement and conditional logic.
- Measurement Reporting — UE sends radio measurements
- Conditional Handover — Condition-based preconfigured handover execution
- Paging Procedure — Network pages UE
