Abstract
This study explores the need for efficient resource allocation in fifth generation (5G) New Radio (NR) sidelink communication for cellular vehicle-to-everything (C-V2X) applications. With the advent of 5G networks, C-V2X can enable direct connection between neighboring vehicles and infrastructure without relying on the cellular network. However, direct communication between devices in 5G NR sidelink makes resource allocation more challenging than in a cellular network. Efficient resource allocation is essential to maintain dependable communication, especially in crowded and interference-prone contexts. There are different type of resource allocation methods such as time-domain, frequency-domain, and power-domain resource allocation, which can be used separately or in combination to achieve efficient resource allocation. In this study, the authors discuss time domain based resource allocation method based on packet generation time and packet allocation time. The implications of efficient resource allocation in 5G NR sidelink in C-V2X include increased signal-to-noise ratio, reduced interference, lower latency, and increased network capacity. The proposed approach is demonstrated on a Network Simulator (NS3.34) along with the traffic scenarios generated using Simulated Urban Mobility (SUMO). Our results demonstrate that time allocation is a promising approach to achieve efficient resource allocation, enabling safer and more effective transportation systems for C-V2X applications.
