Intelligent transport systems — Evolved-universal terrestrial radio access network — Part 3: LTE-V2X
This document provides specifications related to the ITS-S access layer for a communication interface (CI) named "ITS-LTE-V2X". ITS-LTE-V2X CIs are based on the evolved-universal terrestrial radio access (E-UTRA) vehicle-to- everything (LTE-V2X) technology standardized at 3GPP. This document enables usage of the LTE-V2X technology as an ITS access technology in an ITS station by reference to respective specifications from 3GPP, and by specifying details of the "Communication Adaptation Layer" (CAL) and the "Management Adaptation Entity" (MAE) of communication interfaces specified in ISO 21218.

Introduction
Localized communications are an essential component of hybrid communications in Intelligent
Transport Systems (ITS). Various access technologies are suited for localized communications. An
increasing interest of ITS stakeholders for "Cooperative ITS" and "Urban ITS" is in the access technology
known under the acronym of LTE. LTE refers to a packet switched cellular network technology specified
by 3GPP. Beside the "traditional" features of cellular networks, LTE also supports device-to-device
communications, e.g. for public safety applications, and vehicle-to-everything communications (LTE-
V2X) especially designed for ITS.
This document provides complements to LTE-V2X specifications from 3GPP needed to operate it as an
ITS access technology in an ITS station unit specified in ISO 21217. An implementation of this document
is referred to as an ITS-LTE-V2X communication interface (CI).
ITS-LTE-V2X CIs are able to
— operate with support of an LTE base station, and
— operate without support of an LTE base station, e.g. outside LTE coverage areas
as specified by 3GPP.
