The objective of this Technical Report is to identify and evaluate potential architecture enhancements needed to operate LTE-based V2X (V2V, V2I, V2N, and V2P), based on vehicular services requirements defined in SA WG1 V2XLTE (TS 22.185 and TS 22.278) and determine which of the solutions can proceed to normative specifications.
The following documents contain provisions which, through reference in this text, 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. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply.
A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Road Side Unit:
A stationary infrastructure entity supporting V2X applications that can exchange messages with other entities supporting V2X applications.
V2I Service:
a type of V2X Service, where one party is a UE equipped on a vehicle and the other party is an RSU.
V2N Service:
a type of V2X Service, where one party is a UE equipped on a vehicle and the other party is an application server (e.g. traffic safety server).
V2P Service:
a type of V2X Service, where one party is a UE equipped on a vehicle and the other party is a UE which is carried by an individual (e.g. handheld terminal carried by a pedestrian, cyclist, driver or passenger).
V2V Service:
a type of V2X Service, where both parties of the communication are UEs equipped on different vehicles.
V2X message:
message containing V2X application layer information. The V2X message is safety-related V2X message or non-safety-related V2X message.
V2X Service:
a type of communication service to exchange V2X messages that involves a transmitting or receiving UE using V2X application via 3GPP transport. V2X Service is further divivided into V2V Service, V2P Service, V2I Service, and V2N Service.
For the purposes of the present document, the abbreviations given in TR 21.905 and the following apply.
An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905.
