– outside of E-UTRAN coverage;

– within E-UTRAN coverage but not camped on any cell;

– within E-UTRAN coverage but camped on a non-E-UTRAN cell;

– camped on an E-UTRAN cell not indicating that V2X communication over PC5 is supported by the network; or

– camped on an E-UTRAN cell indicating that V2X communication over PC5 is supported by the network and providing carrier frequencies and/or radio resources for V2X communication over PC5 which do not belong to the provisioned carrier frequency that the UE intends to use.
