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.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport Systems
(ITS).
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
Several initiatives had been started to introduce vehicular communication technology for different use cases into
different international standards and industry organizations, which were previously focusing only on ITS-G5. At the
same time, some regulatory bodies are currently considering to mandate C-ITS technologies in order to foster its
deployments.
While LTE-V2X standards are already finalized in 3GPP Rel. 14 and are expected to be deployed for "Day 1" use cases,
there are still many options on how to configure and parameterize the LTE-V2X systems. In order to provide a common
standard interpretation, there is a need for corresponding system profiles, which outline the basic system settings and
environments.
In Europe, Basic System Profiles (BSPs) have been developed by the Car-2-Car Communication Consortium (C2C-CC)
and the EU funded C-ROADS Platform project, assuming ITS-G5 with IEEE specifications as radio access technology
for V2V and V2I communication. Though many aspects of the existing BSPs could be reused, there are some
modifications needed in order to allow applicability for LTE-V2X, which are addressed in the present document.

5 ETSI TS 103 723 V1.2.1 (2020-11)
The objective of the present document is to specify a profile for LTE-V2X by making references to the C2C-CC Basic
System Profile (BSP) and the C-ROADS Roadside ITS-G5 System Profile (RSP) and specifying the differences, in
order to use LTE-V2X for the envisioned "Day 1" use cases provided in these documents. In order for the present
document to be useful for its intended purpose and to make full use of it, the C2C-CC and C_ROADS documents need
to be acquired separately. Where portions of the C2C-CC and C-ROADS documents are not suggested to be modified,
replaced or deleted in creating implementations of the LTE-V2X implementations by the present document, those
portions are considered to apply to LTE-V2X.
Since the C2C-CC and C-ROADS documents are not under the control of ETSI, the present document contains only
incremental changes that need to be applied, referring to the corresponding items that are to be replaced or not
applicable for LTE-V2X. The considered changes are based on Release 1.5.0 of C2C-CC BSP [8] and C2C-CC Feat [9]
as well as Release 1.6 of C-ROADS RSP [13] and C-ROADS MSP [14]. Initial work has been done in 5GAA PC5
BSP [i.1] and 5GAA PC5 RSP [i.2] based on earlier releases. The present document may be revised in the future to take
into account later releases of C2C and C-ROADS deliverables.
C2C-CC documents C2C-CC Trig [10] describing C-ITS triggering conditions, as well as C-ROADS documents
C-ROADS Serv [15] and C-ROADS Func [16] describing C-ITS service and functional requirements, respectively, are
already applicable to LTE-V2X.

1 Scope
The scope of the present document is to identify a common set of standards and specify configuration parameter values
and references required for the implementation of direct communication between ITS stations, to achieve interoperable
deployment of ITS services via V2V and V2I links.
The scope is limited to communication aspects of ITS stations using the single access layer technology LTE-V2X PC5
mode 4. Additional requirements like triggering conditions, position accuracy, security, and functional safety aspects
are out of scope of the present document.
Descriptions, definitions and rules for all layers (Applications, Facilities, Networking & Transport and Access) of the
ETSI ITS station reference architecture are considered as needed.
