1. A method implemented at a first terminal device, comprising:
obtaining information about one or more candidate communication technologies for at least one vehicle-to-anything (V2X) service;
determining availability of the one or more candidate communication technologies;
selecting at least a first communication technology from the one or more candidate communication technologies for communication between the first terminal device and at least a second terminal device based on the availability of the one or more candidate communication technologies;
after selecting the first communication technology, determining that the first communication technology is unavailable or is going to become unavailable; and
after determining that the first communication technology becomes or is going to become unavailable, using a second communication technology from the one or more candidate communication technologies to communicate with the second terminal device, wherein
the first communication technology is a radio interface between the first terminal device and a network node of a radio access network (RAN) and the second communication technology is a sidelink interface between the first terminal device and the second terminal device allowing the first communication device to directly communicate with the second terminal device, or
the first communication technology is a sidelink interface between the first terminal device and the second terminal device allowing the first communication device to directly communicate with the second terminal device and the second communication technology is a radio interface between the first terminal device and a network node of a radio access network (RAN).
