General Technical Requirements of LTE-Based
Vehicular Communication
1 Scope
This Standard specifies the overall service requirements, system architecture and
basic functional requirements of LTE-based vehicular communication.
This Standard is applicable to LTE-based vehicular communication systems.

3.1 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
4 Overview
Vehicle-to-Everything (V2X) applications include Vehicle-to-Vehicle (V2V) applications,
Vehicle-to-Infrastructure (V2I) applications, Vehicle-to-Network (V2N) applications and
Vehicle-to-Pedestrian (V2P) applications.
V2V application refers to the exchange of V2V application information between
adjacent on-board UEs. The information exchange is based on the broadcast mode,
and the direct mode between UEs may be used, or information may be exchanged
between UEs through infrastructure [such as road side unit (RSU), application server].
V2I application refers to the on-board UE sends V2I application information to the RSU
or local application server; and the RSU or local application server sends the V2I
application information to the on-board UE.
V2N application refers to communication between UE and application server through
EPS network.
V2P application refers to the exchange of V2P application information between an on-
board UE and a human-held UE. Information exchange may adopt the direct mode
between UEs, or exchange information between UEs via infrastructure [such as road
side unit (RSU), application server].
The LTE-based vehicular communication system supports Vehicle-to-Vehicle (V2V)
applications, Vehicle-to-Infrastructure (V2I) applications, Vehicle-to-Network (V2N)
applications, and Vehicle-to-Pedestrian (V2P) applications. These applications may
provide users with various services such as road safety, traffic efficiency improvement
and infotainment, etc. Appendix A provides application scenarios and demand analysis
LTE-based Vehicle-to-Everything.
5 General Service Requirements of LTE-Based Vehicle-
to-Everything
5.1 Basic requirements
Requirement 1: When the sending terminal is served by E-UTRAN that supports V2X,
the message transmission shall be controlled by the 3GPP network.
Requirement 2: When the Vehicle-to-Everything terminal fails to be served by the E-
UTRAN network that supports V2X, it shall be able to support and use the 3GPP
network to pre-configure the system parameters for sending and receiving messages.
Requirement 3: Whether or not it is served by the E-UTRAN network that supports
5.2 Effective communication distance
Requirement 16: E-UTRA shall be able to provide sufficient effective communication
distance to ensure that the driver has sufficient response time (for instance, 4s).
5.3 Movement speed
Requirement 17: Regardless of whether the Vehicle-to-Everything terminal uses the
Vehicle-to-Everything communication service that is provided by E-UTRAN that
supports V2X communication, the 3GPP system shall be able to support messages
sending between vehicles at a maximum relative speed of 500km/h.
Requirement 18: Regardless of whether the Vehicle-to-Everything terminal or road
side unit or pedestrians use the Vehicle-to-Everything communication service that is
provided by E-UTRAN that supports V2X communication, the 3GPP system shall be
able to support the message sending between vehicles and vehicles at a maximum
absolute speed of 250km/h, between vehicles and road side units, as well as between
vehicles and pedestrians send messages.
5.4 Communication delay
Requirement 19: For terminals that support vehicle-to-vehicle and vehicle-to-
pedestrian communication, whether it is sent directly or forwarded by a road side unit,
E-UTRA (N) shall ensure that the maximum communication delay not exceed 100ms.
Requirement 20: Only for special use cases (such as collision detection), the maximum
delay of sending V2V messages between E-UTRA (N) Vehicle-to-Everything terminals
should not exceed 20ms.
Requirement 21: For vehicle-to-road side unit communication, the maximum
communication delay between the vehicle and the road side unit does not exceed
100ms.
Requirement 22: For the communication BETWEEN the Vehicle-to-Everything terminal
that supports the V2N service and goes through the 3GPP network entity AND the
application server, the maximum end-to-end delay shall not exceed 1000ms.
5.5 Transmission reliability
Requirement 23: The E-UTRAN network shall not rely on application layer
retransmission to provide highly reliable transmission.
5.6 Requirements for information security
Requirement 24: When the Vehicle-to-Everything terminal uses the service that is
provided by E-UTRAN that supports V2X communication, the 3GPP network shall
provide a method for the operator to authorize the Vehicle-to-Everything terminal to
characteristics (such as delay, message size), and does not pay attention to specific message
types.
