Provided are a radio communication system and user device that enable smooth interworking in a radio resource control (RRC) layer in the case of implementing interworking between systems by LTE assisted 5G, 5G assisted LTE, or the like. The radio communication system includes an eNBconforming to LTE and a 5G-BSconforming to 5G. The eNBincludes an RRC function unitthat performs control based on LTE-RRC, which is an RRC protocol in LTE. The 5G-BSincludes an RRC function unitthat performs control based on 5G-RRC, which is the RRC protocol in 5G. The RRC function unithas at least a function not specified in LTE-RRC.
