Abstract:
In a mobile station (UE) according to the present invention, when a synchronization state determination unit notifies that a downlink synchronization state is a non-synchronization state; (1) when a first timer has expired, and when a second timer is being activated, a radio link failure state determination unit is configured to stop the second timer, and to determine that a current state is a radio link failure state; (2) when the first timer is being activated, and when the second timer is being activated, the radio link failure state determination unit is configured to stop the second timer; or (3) when the first timer is not being activated, the radio link failure state determination unit is configured to start the first timer.
