Adaptive Sidelink Open Loop Power Control Optimization Strategies for Vehicle-to- Vehicle Communications in 5G-NR-V2X

Abstract

In the rapidly evolving landscape of 5G-NR-V2X communication systems, the demand for efficient and adaptive power control mechanisms is paramount to address the challenges posed by high-density vehicular environments. This paper introduces the adaptive sidelink open loop power control (AS-OLPC) algorithm as a pioneering solution. The primary objective is to enhance vehicle-to-vehicle (V2V) communication reliability through real-time signal-to-interference-plus-noise ratio (SINR) estimation, interference level measurements, and dynamic power adjustments. The main problem addressed in this research is the need for improved communication throughput in complex urban scenarios. Our specific objectives involve the development and evaluation of AS-OLPC against conventional open loop power control (OLPC) algorithms. To assess the algorithm’s effectiveness, an extensive simulation setup replicates realistic urban and highway scenarios. Key metrics such as packet reception ratio (PRR), interference levels, and energy efficiency are employed for analysis. The results showcase the adaptability and superior performance of AS-OLPC, establishing it as a promising solution for optimizing communication throughput in 5G-NR-V2X networks.
