Claim 12:
13. A user equipment (UE) performing a vehicle communication, the UE comprising:
a receiver configured to receive sidelink radio bearer configuration information for configuring a sidelink radio bearer on a sidelink interface used for the vehicle communication from a base station;
a controller configured to configure the sidelink radio bearer based on the sidelink radio bearer configuration information, transmit the sidelink radio bearer configuration information to another UE subject to the vehicle communication, and detect a sidelink radio link failure when an acknowledged mode (AM) radio link control (RLC) entity linked to the sidelink radio bearer reaches a maximum number of retransmissions; and
a transmitter configured to transmit the sidelink radio bearer configuration information to another UE subject to the vehicle communication,
wherein the controller instructs the detection of the sidelink radio link failure to a higher layer regardless of a radio resource control (RRC) state of the UE when the sidelink radio link failure is detected.
