Discussion on aspects of integration of sensing with communication
Position extracted by AI
Spreadtrum proposes studying the feasibility of reusing existing 6G DL and UL reference signals (CSI-RS, PRS, DMRS, PTRS, SRS) for sensing, while identifying major challenges including low unambiguous range/velocity and unknown precoding matrices in bistatic scenarios. They propose studying the necessity of dedicated DL/UL sensing reference signals, considering either complete new designs or incremental enhancements to existing signals like increasing CSI-RS density or reconfiguring PTRS/DM-RS. They propose reusing the Rel-20 agreement on measurement report content (Level A through D) as the 6G sensing starting point and studying feasibility and overhead of air-interface reporting for each level. They require sensing reference signals and measurements/reports to support periodic, semi-persistent, and aperiodic configurations, and propose studying sensing processing timeline/unit (SPU) parameters including channel estimation time and sensing algorithm execution time.
Summary
This Spreadtrum/UNISOC document provides analysis on integrating sensing with 6G communication, presenting 2 observations and 6 proposals. It evaluates the feasibility of reusing existing 6G reference signals for sensing, highlights the need for dedicated sensing reference signals, and addresses sensing measurement/report configuration including reusing Rel-20 agreements.
