This document provides specifications related to the ITS-Station (ITS- S) access layer for a communication interface (CI) named "ITS-LTE-D2D".
This specification is appropriate in the context of LTE-D2D communications that are being used for the dissemination of ITS information from an ITS-SU to other ITS-SUs, where these ITS-SUs can be either vehicle ITS-SUs, roadside ITS-SUs, or personal ITS-Sus as specified in ISO 21217 and provides a combination of options from relevant ETSI/3GPP releases and ISO ITS-station management standards to enable and achieve this objective.
ITS-LTE-D2D CIs are based on the evolved-universal terrestrial radio access network (E-UTRAN) device-to- device (LTE-D2D) technology standardized at 3GPP Release 13.
This International Standard(ISO 17515-2) enables usage of the LTE-D2D 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.
