(P) V14.4.0    2017/09    xx p.       (P) V14.3.0    2017/06    38 p.

Rapporteur:  Dr. Kim, Laeyoung
See also:  V2X-related TS/TR    

The present document specifies architecture enhancements to facilitate vehicular communications for Vehicle-toEverything (V2X) services, which includes Vehicle-to-Vehicle (V2V), Vehicle-to-Pedestrian (V2P), Vehicle-toInfrastructure (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.
