RLC Timer Mechanism for RRC Reestablishment After ARQ Failures

The patent implements a timer mechanism that proactively monitors for missing PDU segments and automatically triggers RRC connection reestablishment when the timer expires, eliminating the need to wait for ARQ response timeouts. This preliminary action approach resolves the contradiction by pre-establishing a recovery mechanism that activates before ARQ failures accumulate, thereby reducing latency while maintaining data completeness through systematic segment recovery.

The patent employs a feedback mechanism where the timer monitors PDU segment reception status and provides feedback to trigger RRC connection reestablishment when segmentation failures are detected. This feedback loop automates the recovery process, improving data flow recovery while managing complexity through systematic monitoring and automatic triggering rather than manual intervention or complex error handling logic.

The patent implements a state variable reset mechanism during RRC connection reestablishment that discards stale or corrupted state information while recovering essential communication parameters. This approach resolves the contradiction by systematically discarding only the necessary stale state variables that are no longer valid after connection reestablishment, while recovering and reinitializing critical communication state, thereby improving stability without permanent information loss.
