Intellectual Property Rights
Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.

Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport Systems
(ITS).
The present document is part 7, sub-part 2 of a multi-part deliverable covering Intelligent Transport Systems (ITS);
Vehicular Communications; GeoNetworking, as identified in part 7, sub-part 1 [1].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The Intelligent Transport System (ITS) Communication (ITSC) architecture defined in ETSI EN 302 665 [i.11] 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.12], 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.1] and [i.2]. It has since
been determined that the Basic Transport Protocol (BTP) specified in ETSI EN 302 636-5-1 (V2.1.1) [1] includes
dependencies on the access layer technology, and thus amendments to BTP are needed to enable operation in an ITS
station that utilizes the LTE-V2X access layer technology.
The present document specifies amendments to the BTP 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 302 636-5-1 [1] could
incorporate amendments based on the present document. Upon completion of such revisions to ETSI
EN 302 636-5-1 [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 302 636-5-1 (V2.1.1) [1] to extend BTP for the transport of
packets among ITS stations that utilize LTE-V2X as the access layer technology.
