It includes transport layer support for both safety and non-safety V2X scenarios: - S
23、afety-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 2 References The following documents contain provisions which, through reference in this text,
24、 constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.

31、5.3.0 (2018-07)63GPP TS 22.186 version 15.3.0 Release 15NOTE: 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 appli
32、cation 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
33、 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. 3.2 Abbreviations For the purposes of the present document, the ab
34、breviations given in 3GPP TR 21.905 1 and the following apply.

35、 Provider Service Identifier RSU Road Side Unit 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 t
36、o 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 f
37、orm 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 se
38、cond). 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, thu
39、s 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 o
40、f 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 situati
41、on. 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
42、 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. ETSI ETSI TS 122 186 V15.3.0 (2018-07)73GPP TS 22.186 version 15.3.0 Release 154.2 Level of Automation A relevant aspect of advanced V2X applications is the
43、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 A
44、utomation. 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 5 Requirements 5.1 Gen
