1 Scope p. 7
The present document is a technical report which identifies the enhancements to the application architecture to support V2X services specified in TS 23.286.
The study takes into consideration the existing stage 1 and stage 2 work within 3GPP related to V2X enhancements in TS 22.185, TS 22.186, TS 23.285 and TS 23.287, as well as V2X application requirements defined outside 3GPP.
This document will provide recommendations for normative work.

4 Analysis of V2X standards p. 8
4.1 3GPP 5GS architecture for V2X communications p. 8
4.1.1 Description p. 8
The V2X architecture, functional entities to facilitate vehicular communications for Vehicle-to-Everything (V2X) services, which includes Vehicle-to-Vehicle (V2V), Vehicle-to-Pedestrian (V2P), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Network (V2N) are specified based on 5GS in TS 23.287.
4.1.2 Analysis p. 8
The following reference points described in TS 23.287 have V2X application layer impact:
- V1: The reference point between V2X application in the UE and the V2X application server. This reference point is considered out of scope of TS 23.287.
- V5: The reference point between the V2X applications in the UEs. This reference point is considered out of scope of TS 23.287.
- Authorization and provisioning for V2X communications over PC5 and Uu reference points
- V2X message transmission/reception over PC5 or Uu reference points
- V2X Application Server discovery
- QoS handling for V2X communication over PC5 and Uu reference points
- Interworking between EPS V2X and 5GS V2X
