Title: INTERWORKING SYSTEM AND OPERATION IN V2X APPLICATIONS
Abstract: [0001]    A communication system and method for supporting a plurality of vehicle-to-everything radio access technologies (V2X RATs) is provided. The communication system configured to support multiple V2X RATs transmits, using a first V2X RAT, an indication of its availability to support an interworking function between the plurality of V2X RATs. The communication system receives an instruction to provide the interworking function between different V2X RATs. The interworking function may be incorporated in a vehicle that is joined to a platoon configured to use a first V2X RAT, and provide the interworking function between the first and a second V2X RAT. The interworking function may be used to add further vehicles to the platoon that communicate using only the second V2X RAT.
