V3 V4 V6

Rapporteur: Dr. Kim, Laeyoung

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.
