Terminal Measurement State Switching for RLM and BFD Power Control

The patent implements dynamic measurement state adjustment by introducing multiple measurement states (first measurement state with higher capability and second measurement state with lower capability) that can be switched based on communication conditions. The terminal dynamically transitions between these states to optimize measurement capability while managing complexity through state-based control rather than continuous adjustment.

The patent implements periodic measurement actions by introducing timers that control when measurements occur in different states. In the first measurement state, measurements are performed more frequently with shorter timer intervals, while in the second measurement state, measurements are performed less frequently with longer timer intervals, optimizing the balance between measurement capability and power consumption through time-based periodic control.

The patent applies preliminary action by pre-configuring measurement parameters, timer values, and state transition conditions before actual measurement needs arise. The terminal evaluates communication conditions against pre-defined criteria and transitions between measurement states based on pre-established rules, avoiding ad-hoc decision-making and reducing the time lost during state transitions.
