On integration of sensing and communications in 6GR
Position extracted by AI
Nokia proposes TDM-based sensing RS as the baseline candidate for 6G sensing integration, with FDM-based approaches identified for further study without precluding coexistence with the baseline. They recommend CSI-RS or SRS as the basis for sensing RS design—explicitly rejecting NR PRS due to its single-port limitation—and propose studying enhancements to legacy RS resource element mappings to support non-contiguous, evenly-spaced OFDM symbols across multiple contiguous slots (time-domain comb structures). For measurement reporting, they consider NR Rel-20 ISAC data levels A/B/C/D as the baseline framework and support TRP-based reporting as the baseline. Nokia highlights that bistatic sensing may incur large overhead from beam sweeping at both STX and SRX, and proposes studying mechanisms to avoid this excessive overhead.
Summary
This Nokia contribution on 6G sensing integration contains 12 proposals and 2 observations, covering sensing RS design, multiplexing, measurement/reporting frameworks, beam management, and sensing-assisted communications. The document establishes TDM-based sensing RS as a baseline, proposes basing sensing RS on CSI-RS/SRS, and recommends studying enhancements for multi-slot RE mappings, PxSCH-based sensing, and sensing-for-communication use cases like beam management and UE location integration.
