Research Objective: This paper introduces I-SCOUT, a novel framework that leverages existing 5G network infrastructure and Positioning Reference Signals (PRS) for simultaneous communication and environment sensing, specifically targeting moving target detection.
Methodology: I-SCOUT repurposes 5G PRS, known for their distinctive autocorrelation characteristics, for environmental sensing. The system transmits PRS signals, and upon reflection from moving targets, captures and processes them using the cross ambiguity function (CAF) to estimate the targets' range and velocity. The research analyzes the tradeoff between sensing and communication functionalities by adjusting the number of PRSs allocated for ISAC, aiming to optimize both sensing accuracy (measured by Root Mean Squared Error - RMSE) and communication efficiency.
Key Findings: I-SCOUT effectively leverages ISAC to accurately determine the range and velocity of moving targets. The study demonstrates that the number of PRSs dedicated to ISAC significantly impacts system performance, necessitating a careful balance between sensing accuracy and communication efficiency. Furthermore, I-SCOUT can distinguish between multiple targets within a group, highlighting its potential for complex scenarios.
Main Conclusions: I-SCOUT showcases the viability of ISAC in enhancing NextG network capabilities for both commercial and tactical applications where precision and reliability are critical. The proposed framework offers a promising solution for integrating sensing capabilities into existing communication infrastructure without imposing significant overhead.
Significance: This research contributes to the advancement of ISAC technology by proposing a practical and efficient framework for integrating sensing capabilities into existing 5G networks. The findings have significant implications for various applications, including autonomous driving, smart cities, and enhanced situational awareness in defense scenarios.
Limitations and Future Research: The study focuses on a simplified 5G network deployment with a limited number of targets. Future research could explore the performance of I-SCOUT in more complex and dynamic network environments with a larger number of targets and diverse mobility patterns. Additionally, investigating the integration of I-SCOUT with other sensing modalities, such as computer vision, could further enhance target detection accuracy and reliability.
