1. A method of performing a vehicle communication by a user equipment (UE), the method comprising:
receiving sidelink radio bearer configuration information for configuring a sidelink radio bearer on a sidelink interface used for the vehicle communication from a base station;
configuring the sidelink radio bearer based on the sidelink radio bearer configuration information, and transmitting the sidelink radio bearer configuration information to another UE subject to the vehicle communication;
detecting 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
indicating the detection of the sidelink radio link failure to a higher layer regardless of the radio resource control (RRC) state of the UE when the sidelink radio link failure is detected.
