3rd Generation Partnership Project

Introduced initial LTE-based Cellular V2X specifications supporting direct vehicle communications and network-assisted V2X services.

3GPP TS 22.185 defines service requirements for vehicle, pedestrian, infrastructure, and network V2X communication. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 23.285 defines the LTE-system architecture, procedures, and interfaces supporting V2X communication. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 24.386 defines protocol procedures between user equipment and control functions for V2X authorization and configuration. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 36.300 defines the overall LTE radio architecture that includes the basis for LTE sidelink V2X operation. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 36.321 defines LTE medium-access procedures, including resource handling for sidelink communication. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 36.331 defines LTE radio-resource-control signaling, including configuration relevant to sidelink V2X. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 38.300 defines the overall 5G New Radio architecture that frames NR sidelink and network operation. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 38.321 defines 5G medium-access procedures used to schedule and operate NR radio links, including sidelink. It matters to V2X because it gives independently developed systems a common technical contract.

3GPP TS 38.331 defines 5G radio-resource-control signaling, including configuration of NR sidelink. It matters to V2X because it gives independently developed systems a common technical contract.

5G-V2X extends cellular vehicle communications with higher capacity, lower latency, improved reliability, and support for advanced cooperative and automated driving applications.

Cellular Vehicle-to-Everything is a communications technology that allows vehicles to exchange safety, traffic, and mobility information with other vehicles, infrastructure, pedestrians, and cellular networks.

LTE-V2X is the initial cellular V2X generation based on LTE technology, supporting direct vehicle communications and network-assisted V2X services.

The 3GPP Release 16 direct sidelink technology for advanced V2X communication.

The 3GPP direct radio interface used for device-to-device V2X communication without routing traffic through the cellular network.
