C-V2X 5G: Cellular Vehicle to Everything Explained

This page describes C-V2X basics, including its features in 5G. The combination of V2V, V2P, V2I, and V2N is known as V2X.

C-V2X is short for Cellular to Everything, covering V2V, V2P, V2I, and V2N.

What is C-V2X?

As mentioned, C-V2X stands for Cellular Vehicle to Everything. It refers to a network that combines features of:

• V2V (Vehicle to Vehicle)
• V2P (Vehicle to Pedestrian)
• V2I (Vehicle to Infrastructure)
• V2N (Vehicle to Network)

Figure 1 depicts this concept.

It fulfills our vision to create autonomous vehicles and safer autonomous driving experiences. The latest wireless standard, 5G release 14 and beyond, makes C-V2X a reality in today’s world.

Features Introduced by C-V2X

Following are the features introduced by C-V2X:

• Non-Line of Sight (NLOS) Sensing: Provides 360° NLOS awareness.
  • Use cases: Road intersections, blind intersections, environmental conditions (e.g., rain, fog).
• High Level of Predictability: Based on installed sensors.
  • Use cases: Alert for sudden lane changes or other road hazards.
• Safety Alerts: As per situational awareness.
  • Use cases: Conditions such as reduced speed, queue warning, etc.
