Scope

This document specifies the design requirements, system architecture, and functional requirements of the direct-connect communication positioning and synchronization system for LTE-based vehicle networking wireless communication technology under no-GNSS signal conditions, as well as the system workflow, signaling format, and transmission parameters, and the technical requirements and testing methods for roadside equipment/vehicle-mounted terminals. This document is applicable to roadside units (RSUs) that operate under no-GNSS signal conditions and support both positioning and synchronization functions based on LTE-V2X direct-connect communication; it is also applicable to vehicle-mounted units (OBUs) that support synchronization functions based on LTE-V2X direct-connect communication and can use other technologies such as inertial navigation for positioning functions.
