Abstract:
In a mobile station (UE) according to the present invention, a radio link failure state determination unit determines whether or not the mobile station (UE) is in a radio link failure state, based on a downlink synchronization state and a discontinuous reception state parameter, when the mobile station (UE) is in a discontinuous reception state. The radio link failure state determination unit determines whether or not the mobile station (UE) is in the radio link failure state, based on the downlink synchronization state and a non-discontinuous reception state parameter, when the mobile station (UE) is not in the discontinuous reception state.
