1 Scope
The present document specifies service requirements to enhance 3GPP support for V2X scenarios in the 3GPP systems
(i.e. EPS, 5G).
It includes transport layer support for both safety and non-safety V2X scenarios:
- Safety-related V2X scenarios: e.g. automated driving, vehicle platooning
- Non-safety-related V2X scenarios: e.g., mobile high data rate entertainment, mobile hotspot/office/home,
dynamic digital map update

3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following
apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP
TR 21.905 [1].
End-to-end latency: Time it takes to transfer a given piece of information from a source to a destination, measured at
the application level, from the moment it is transmitted by the source to the moment it is received at the destination.
Reliability (%): The success probability of transmitting X bytes within a certain delay, which is the time it takes to
deliver a small data packet from the radio protocol layer 2/3 SDU ingress point to the radio protocol layer 2/3 SDU
egress point of the radio interface.
Road Side Unit: A stationary infrastructure entity supporting V2X applications that can exchange messages with other
entities supporting V2X applications.

NOTE: RSU is a term frequently used in existing ITS specifications, and the reason for introducing the term in
the 3GPP specifications is to make the documents easier to read for the ITS industry. RSU is a logical
entity that supports V2X application logic using the functionality provided by either a 3GPP network or
an UE (referred to as UE-type RSU).
For the purposes of the present document, the following terms and definitions given in ISO TS 17419 [5] apply:
ITS Application Identifier: globally unique, registered number identifying an ITS application object
For the purposes of the present document, the following term and definition given in IEEE Std 1609.0 [6] apply:
Provider Service Identifier: An identifier of an application-service provided by a higher layer entity.

For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 [1] and the following apply. An
abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in
3GPP TR 21.905 [1].

4 Overview
4.1 Categories of requirements to support eV2X scenarios
Different V2X scenarios require the transport of V2X messages with different performance requirements for the 3GPP
system. This Technical Specification specifies service requirements to enhance 3GPP support for V2X scenarios in the
following five areas:
- General Aspects: interworking, communication-related requirements valid for all V2X scenarios
- Vehicles Platooning
- Advanced Driving
- Extended Sensors
- Remote Driving
Vehicles Platooning enables the vehicles to dynamically form a group travelling together. All the vehicles in the platoon
receive periodic data from the leading vehicle, in order to carry on platoon operations. This information allows the
distance between vehicles to become extremely small, i.e., the gap distance translated to time can be very low (sub
second). Platooning applications may allow the vehicles following to be autonomously driven.
Advanced Driving enables semi-automated or fully-automated driving. Longer inter-vehicle distance is assumed. Each
vehicle and/or RSU shares data obtained from its local sensors with vehicles in proximity, thus allowing vehicles to
coordinate their trajectories or maneuvers. In addition, each vehicle shares its driving intention with vehicles in
proximity. The benefits of this use case group are safer traveling, collision avoidance, and improved traffic efficiency.
Extended Sensors enables the exchange of raw or processed data gathered through local sensors or live video data
among vehicles, RSUs, devices of pedestrians and V2X application servers. The vehicles can enhance the perception of
their environment beyond what their own sensors can detect and have a more holistic view of the local situation.
Remote Driving enables a remote driver or a V2X application to operate a remote vehicle for those passengers who
cannot drive themselves or a remote vehicle located in dangerous environments. For a case where variation is limited
and routes are predictable, such as public transportation, driving based on cloud computing can be used. In addition,
access to cloud-based back-end service platform can be considered for this use case group.

4.2 Level of Automation
A relevant aspect of advanced V2X applications is the Level of Automation (LoA), which reflects the functional aspects
of the technology and affects the system performance requirements. In accordance with the levels from SAE [4], the
LoA are: 0 – No Automation, 1 – Driver Assistance, 2 – Partial Automation, 3 – Conditional Automation, 4 – High
Automation, 5 – Full Automation.
A distinction is drawn between lower levels and higher levels based on whether the human operator or the automated
system is primarily responsible for monitoring the driving environment.
The 3GPP system provides the performances expected for all levels of automation
