Abstract
A method for changing layer 2 (L2) identifiers (ID)s during an ongoing vehicle-to-everything session between a source wireless transmit/receive unit (WTRU) and a peer WTRU includes communicating between the source and a peer WTRUs based on existing L2 IDs and an existing session ID. On a condition that a trigger event occurs, the source WTRU and the peer WTRU each generate new L2 IDs as well as respective portions of a new session ID. The new L2 IDs are subsequently used along with the new session ID to increase privacy of communication between the source WTRU and the peer WTRU.
