Architectural Enhancements for Efficient Sensing Data Utilization in 6G ISAC
🤖 AI Summary
This work addresses a critical limitation in existing 6G integrated sensing and communication (ISAC) architectures—the lack of effective storage and utilization of historical sensing data, which hinders the accuracy and efficiency of AI-driven perception. To overcome this, the paper introduces, for the first time, a sensing data storage mechanism within 6G networks that fuses historical and real-time sensing data. By incorporating map-aided hard filtering that leverages static environmental information, the proposed approach enables cooperative refinement of perception outcomes. Simulation results in an urban intersection scenario demonstrate that the architecture significantly reduces false alarm rates while maintaining high detection probability, thereby validating its effectiveness and innovation in enhancing sensing performance.

📝 Abstract
Current architecture proposals within standards development organizations such as ETSI and 3GPP enable sensing capabilities in mobile networks; however, they do not include a repository for storing sensing data. Such a repository can be used for AI model training and to complement ongoing sensing service provisioning by improving efficiency and accuracy. One way of realizing this is through the fusion of historical sensing data with live sensing data. In this paper, we study historical and live sensing data fusion for Integrated Sensing and Communication in future 6G systems and introduce a Sensing Data Storage Function to store historical sensing data and sensing results. We show how the Sensing Data Storage Function can be used with other network functions in a 6G architecture proposition for Integrated Sensing and Communication. We validate our proposal with a measurement model and show performance improvements in terms of detection probability and false-alarm rate. The network functionality to fuse and process sensing data combines live sensing measurements with previously sensed historical sensing data using a map-aware hard filter that rejects detections consistent with known static structures. Our simulation illustrates that, for a traffic junction scenario, map-aware hard filtering substantially reduces false alarms without degrading detection probability.
