Introduction
The Intelligent Transport System (ITS) Communication (ITSC) architecture defined in ETSI EN 302 665 [i.20] is
intended to support a variety of existing and new access technologies and ITS applications. The ITS station reference
architecture also follows the principles of the Open Systems Interconnection (OSI) model [i.19], in which layering
provides modularity and the flexibility to support different protocols at various layers. However, several protocols that
have been defined in accordance with the ITSC architecture include cross-layer dependencies on other protocols also
intended for use within an ITS station. Recently, a new access layer technology for ITS communication, commonly
rd
referred to as LTE-V2X, has been specified by the 3 Generation Partnership Project (3GPP) [i.17] and [i.18]. It has
since been determined that the GeoNetworking Media-Independent Functionality specified in ETSI
EN 302 636-4-1 (V1.3.1) [1] includes dependencies on the access layer technology, and thus amendments to
GeoNetworking Media-Independent Functionality are needed to enable operation in an ITS station that utilizes the
LTE-V2X access layer technology.
The present document specifies amendments to the GeoNetworking Media-Independent Functionality specification as
needed to support LTE-V2X as an underlying access layer technology of an ITS station. It is possible that a future
revision of ETSI EN 302 636-4-1 [1] could incorporate amendments based on the present document. Upon completion
of such revisions to ETSI EN 302 636-4-1 [1], consideration might be given as to whether the present document could
be subsequently withdrawn.

1 Scope
The present document specifies amendments to ETSI EN 302 636-4-1 (V1.3.1) [1] to extend the GeoNetworking
protocol for communication of packets among ITS stations that utilize LTE-V2X as the access layer technology.
