Latency Analysis for Real-Time Sensor Sharing Using 4G/5G C-V2X Uu Interfaces

With the development of communications, various applications communication technologies, such as remote driving, delivery drones, and telesurgery, are emerging. In particular, in many cases, these need real-time video transmission services, they should support low latency for operation reliability quick response emergencies. Sensor sharing is required to advanced but analysis device-to-remote users or servers with high data traffic insufficient. Most related works have device-to-device messages basic device status sharing. However, sensor between a server user essential services autonomous driving utilizing offloading by via base station server. Therefore, this paper, we analyze end-to-end elements sharing, which most representative 4G long-term evolution (LTE) 5G new radio (NR) Uu interfaces. addition, derive supportable resolution according raw encoded each system. For level, significant effect on latency. Depending system, investigate number sensor-sharing system that can be supported at same time. Simulation results show LTE interface supports up full definition (FHD) resolution, ultrahigh (UHD). Additionally, only single FHD level interface, whereas 19 interface.
