The present document specifies architecture enhancements 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), according to the use cases and service requirements defined in
TS 22.185.
The following vehicular communications for V2X services are specified:
- V2X communication over PC5 reference point.
- V2X communication over LTE-Uu reference point.
