3 Definitions and abbreviations p. 8

3.1 Definitions p. 8

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.

Application Layer connection-less group:

An application layer group without group formation in the V2X application layer, e.g., sensor sharing.

Application Layer ID:

An identifier identifying an entity, e.g. a vehicle, a pedestrian, an RSU within the context of a specific V2X application. The format of this identifier is outside the scope of 3GPP.

Application Layer managed group:

An application layer group with group formation and management in the V2X application layer, e.g., platooning, cooperative adaptive cruise control.

Groupcast mode communication:

It refers to V2X communication over PC5 reference point within a group of UEs where any UE in the group can act as transmitting UE and the rest act as receiving UEs. See also TS 38.300 for more information. The "group" here refers to Application Layer managed group or Application Layer connection-less group.

Member ID:

An identifier uniquely identifying a member in the Application Layer managed group and that is managed by the V2X application layer.

Mode of communication:

Mode of communication to be used by the UE over PC5 reference point i.e. broadcast mode (LTE PC5 and NR PC5), groupcast mode (NR PC5) or unicast mode (NR PC5).

NR Tx Profile:

The transmission mechanism or format to be used by the UE over NR PC5 RAT (e.g. PC5 DRX support or not, backward compatible or not), see TS 38.300 and TS 38.331.

V2X application:

An application using one or more V2X services e.g. an active safety application in a vehicle, using V2X services such as emergency warning and vehicle to vehicle safety and awareness. A V2X application may operate towards a V2X Application Server.

V2X communication:

A communication to support Vehicle-to-Everything (V2X) services leveraging Uu and / or PC5 reference points. V2X services are realized by various types of V2X applications, i.e. Vehicle-to-Vehicle (V2V), Vehicle-to-Pedestrian (V2P), Vehicle-to-Infrastructure (V2I) and Vehicle-to-Network (V2N).

V2X message:

A dedicated messaging type of V2X service, for example ITS messages.

V2X service:

A data service, offered to V2X applications and optionally V2X Application Servers. A V2X service belongs to one V2X service type. It may include message or other data delivery, as defined in TS 22.185 and TS 22.186. A V2X service can be associated with one or more V2X applications, and a V2X application can be associated with one or more V2X services.

V2X service type:

A type of V2X service, which is identified by e.g. ITS-AID (ITS Application Identifier), PSID (Provider Service Identifier) or AID (Application Identifier).
