1. A method of performing a conditional handover by a user equipment (UE) supporting vehicle-to-everything (V2X) communication, the method comprising:
transmitting a measurement report to a first base station;
receiving a radio resource control (RRC) reconfiguration message from the first base station, wherein the RRC reconfiguration message comprises information regarding at least one execution condition for the conditional handover and resource configuration information for V2X ;
identifying a target cell for execution of the conditional handover, based on the information regarding the at least one execution condition for the conditional handover;
performing the V2X communication based on the resource configuration information for V2X, for the identified target cell; and
transmitting an RRC reconfiguration complete message to a second base station,
wherein the resource configuration information for V2X comprises resource pool configuration information for long term evolution (LTE) V2X and resource pool configuration information for new radio (NR) V2X, and
wherein the resource pool configuration information for LTE V2X comprises exceptional resource pool configuration information for LTE V2X, and the resource pool configuration information for NR V2X comprises exceptional resource pool configuration information for NR V2X.
