- In LTE and NR, the user equipment initiates a recovery procedure when a radio link failure (RLF) is declared. A shorter RLF timer T312 is introduced to speed up the recovery from an RLF and lower the outage time during a handover. However, T312 cannot remove the outage time completely and guarantee a successful recovery. In this letter, an event-based faster RLF trigger scheme is proposed to remedy the shortcomings of T312. The simulation results show that the proposed scheme can almost fully remove the outage time and reduce the interruption time caused by the recovery procedure, outperforming T312.
