3 JustificationThe pace of LTE network deployment is accelerating all over the world, which enables more and more advanced services and Internet applications making use of the inherent benefits of LTE such as higher data rate, lower latency and enhanced coverage, etc. Widely deployed LTE based infrastructure provides the opportunity for the vehicle industry to realize the concept of ‘connected car’. By providing a vehicle access into the LTE network infrastructure, a vehicle can be connected to the Internet and other vehicles so that a broad range of existing or new services can be envisaged for the vehicle industry and the mobile industry as well.

Importantly, Proximity Service (ProSe) introduced in Release 12 will also provide functionalities to implement V2X services. Furthermore, LTE-based broadcast services such as PWS and eMBMS could provide additional functionalities for V2X services. It can be considered that some services will rely on wide-area network access which may be provided by GSM, UMTS, or by LTE.

This study proposes to document V2X use cases and assess the applicability of LTE technology to meet the operator, end-user and automotive industry expectations.

Various potential benefits obtained from LTE V2X from the perspective of LTE technology itself, service provider, car makers and driver/passengers are summarized below.

Service Provider Aspects:

- MNO/MVNO:

Increase of new subscribers (or subscriber units equipped in vehicle), by providing car drivers/passengers with various smart phone-based safety apps and non-safety apps

Possibility of new business models

- Non-MNO: Application Service Provider, etc.

Opportunity to develop and market new services specifically targeted to the automotive industry

Automotive Industry Aspects:

- To be provided with more enriching V2X services by means of LTE technology, well-deployed LTE infrastructure and the internet connection

- To be provided with new business opportunities:

Exploiting the existing business models in 3GPP LTE market place

Possibility of emerging business models based on future ICT (information and communication technology) and evolved LTE technology

Driver/Passenger/Pedestrian Aspects:

- To be provided with safety or driver assistant services and applications

To be provided with vital and supplemental means for special role players (e.g., drivers, conductors) and/or others (e.g., passengers or pedestrians), e.g., notification of “unknown

deterministic” things (e.g., barely visible obstacles in the corner of the road) prior to the unassisted detection by human eyes.

Supplementary information allowing to optimise the route taken and thus saving time, resources

and reducing on pollution.

- To be provided with information related to traffic control and efficiency

- More efficient pedestrian (and other road sharing users) protection services

Road authority aspects

- Road Authorities will receive information on:

Safety aspects e.g. dangerous parts of roads

Maintenance needs of roads and roadside equipment

Traffic patterns and behaviour

- Road Authorities will be able to:

Better control traffic flow

Improve safety related issues identified

ETSI Intelligent Transport Systems (ITS) activity-related to this topic will be considered.

4 ObjectiveThe essential use cases for LTE V2X (V2V, V2I, and V2P) to be studied and requirements identified in 3GPP SA WG1

are as follows;

• V2V: covering LTE-based communication between vehicles.

• V2P: covering LTE-based communication between a vehicle and a device carried by an individual (e.g. handheld terminal carried by a pedestrian, cyclist, driver or passenger).

• V2I: covering LTE-based communication between a vehicle and a roadside unit. A roadside unit (RSU) is a transportation infrastructure entity (e.g. an entity transmitting speed notifications).

In this study the following would be considered:

• The use cases include both safety services and non-safety services.

• The study should consider the possibility of using existing LTE technologies for unicast/multicast/broadcast communication.

• Privacy aspects should be considered, not only to comply with local regulations but also to facilitate acceptance by the end users.

The objective of this study is to identify use cases and associated potential requirements for LTE support of V2X services taking into account V2X services and parameters defined in other SDOs (e.g. GSMA Connected Car, ETSI ITS (Intelligent Transportation System), US SAE) or related governmental agency (e.g. C-ITS project in Korean Ministry of Land, Transport and Maritime Affairs).
