Central Controller: 3GPP C-V2X Modem — Dual-RAT LTE-V2X and 5G NR sidelink

CellV2X는 3GPP 셀룰러 차량 통신을 탐구하여 직접 PC5 및 광역 Uu 인터페이스 전반에서 Rel-14/15 LTE-V2X와 Rel-16/17 5G NR 사이드링크를 벤치마킹합니다.

Autonomous Resource Allocation: Mode 4 & Mode 2 — Sensing-based semi-persistent scheduling (SPS) allowing direct vehicle communication with zero cellular network coverage.
5G NR Rel-16 Sidelink Enhancements — Unicast, groupcast, and broadcast transmission with physical layer HARQ feedback and adaptive subcarrier spacing.
PC5 and Uu Hybrid Dual-Mode Operations — Using wide-area 5G Uu for high-throughput map streaming while reserving dedicated PC5 for mission-critical tactile safety.
