Discussion on performance evaluation for 6GR ISAC
From Spreadtrum
Summary
This document from Spreadtrum/UNISOC proposes a structured evaluation framework for 6G Integrated Sensing and Communication (ISAC), containing 6 total proposals. It defines deployment scenario-to-target type mapping, a phased evaluation approach prioritizing target detection then tracking, baseline sensing modes and metrics, and argues against extending the existing channel model.
Position
Spreadtrum/UNISOC proposes adopting a specific mapping between deployment scenarios (UMa and InF) and target types (UAV, vehicle, outdoor human, indoor human, AGV) for 6GR ISAC evaluation. They require a phased evaluation approach prioritizing target detection as the first use case and target tracking as the second use case to control workload. They propose TRP-involved sensing modes (TRP mono-static, TRP-TRP bi-static, TRP-UE bi-static, UE-TRP bi-static) as the baseline, and require assuming pedestrian UE type to isolate target mobility from sensing node mobility impacts. They argue that extension of the existing Rel-19 channel model is not necessary for these target use cases and simulation scenarios. For target tracking, they propose introducing a new metric called 'tracking outage probability' defined via 3D positioning error threshold, and prioritize vehicles, UAVs, and AGVs over humans due to continuous trajectory requirements.
Key proposals
- Proposal 1 (Sec 2.1): It is proposed to adopt the mapping between deployment scenarios and target types as summarized in Table 1.
- Proposal 1 (Sec 2.2): It is proposed to consider target detection as the first use case for evaluation, and target tracking as the second use case for evaluation to control the overall evaluation workload.
- Proposal 1 (Sec 2.2.1): It is proposed to consider TRP-involved sensing modes (i.e., TRP mono-static, TRP-TRP bi-static, TRP-UE bi-static and UE-TRP bi-static) as the baseline.
- Proposal 2 (Sec 2.2.1): It is proposed to adopt the evaluation framework for target detection as summarized in Table 2.
- Proposal 1 (Sec 2.2.2): It is proposed to adopt the evaluation framework for target tracking as summarized in Table 3.
- Proposal 1 (Sec 2.3): Extension of the existing channel model is not necessary for 6GR ISAC target use cases and simulation scenarios.
