Operating model
How LTE-V2X works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
LTE-V2X is the first standardized cellular V2X generation, introduced through 3GPP Release 14. Its PC5 sidelink supports direct communication outside normal cellular coverage, while the cellular interface supports network services. LTE-V2X remains a deployed C-V2X technology and is designed to coexist with later NR-V2X capabilities rather than being interchangeable with them.

Interoperability
Standards
Release 14
Introduced initial LTE-based Cellular V2X specifications supporting direct vehicle communications and network-assisted V2X services.
3GPP TS 23.285
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
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
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
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
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.
SAE J3161/1
SAE J3161/1 defines minimum LTE-V2X on-board performance for V2V safety applications. It matters to V2X because it gives independently developed systems a common technical contract.
