Summary of Agreements by Topic

ISAC Deployment Scenarios

1. General Principles:
• Deployment scenarios prioritize sensing targets such as UAVs, humans, vehicles, AGVs, and objects creating hazards.
• Minimum distances between sensing targets and Tx/Rx are defined based on far-field assumptions.
• Sensing modes include monostatic, bistatic, and multi-static configurations.
2. Specific Scenarios:
• UAVs:
• Small UAVs (0.3m x 0.4m x 0.2m) are uniformly distributed within the center cell.
• Fixed height of 200m for aerial UEs.
• RCS values include component A (-12.81 dBsm), B1 (0 dB), and B2 (standard deviation: 3.74 dB).
• Automotive:
• Vehicle type 2 (passenger vehicles) with 5 scattering points (front, back, left, right, roof).
• Urban grid and highway scenarios with speeds of 60 km/h and 140 km/h, respectively.
• RCS component A (-20 dBsm).
• Humans:
• Indoor and outdoor scenarios with child and adult pedestrian sizes.
• RCS model 1 and model 2 supported.
• AGVs:
• Indoor factory scenarios with AGVs distributed uniformly.
• RCS component A (-20 dBsm).
• Objects Creating Hazards:
• Scenarios include highways, urban grids, and high-speed trains.
• RCS values for humans, animals, and other targets.

ISAC Channel Modeling

1. Channel Generation:
• Separate generation of target and background channels.
• Absolute delay model is mandatory for UMi, UMa, InH, and InF scenarios.
• Spatial consistency is supported for certain links (e.g., between the same target and multiple nodes).
2. RCS Modeling:
• RCS values are generated using AB1B2, where:
• A is deterministic and dependent on target type.
• B1 is angle-dependent.
• B2 follows a log-normal distribution.
• Specific RCS values/patterns are defined for UAVs, humans, vehicles, and AGVs.
3. Background Channel:
• Reference points are dropped based on Gamma distribution for distance and height.
• LOS and NLOS clusters are generated using TR 38.901 as a starting point.
• Power threshold for removing clusters is set at -25 dB.
4. Polarization Matrix:
• Polarization matrix for direct/indirect paths is normalized.
• XPR ratios and initial random phases are defined for targets.

Calibration Parameters

1. Large-Scale Calibration:
• Parameters include carrier frequency, bandwidth, Tx power, antenna configurations, and sensing target distributions.
• Metrics include coupling loss for target and background channels.
2. Full Calibration:
• Includes fast fading models and detailed metrics such as delay spread and angle spread.
• Absolute delay models are reused from existing TRs.
3. Specific Target Calibration:
• UAVs: Component A (-12.81 dBsm), B1 (0 dB), B2 (3.74 dB standard deviation).
• Vehicles: Component A (-20 dBsm), B1 and B2 values vary based on scattering points.
• Humans: Component A (-1.37 dBsm), B1 (0 dB), B2 (3.94 dB standard deviation).

Spatial Consistency

1. Correlation Types:
• Parameters such as delays, cluster powers, angles, and LOS/NLOS states are correlated based on spatial consistency.
• Spatial consistency is not modeled for links between non-co-located TRPs or links with different LOS/NLOS conditions.
2. Scattering Points:
• Multiple scattering points for targets are individually handled.
• Locations and RCS values of scattering points are consistent across Tx/Rx pairs.

Metrics

1. Coupling Loss:
• Defined for both target and background channels.
• Includes pathloss, shadow fading, and RCS components.
2. CDFs:
• Separate CDFs for target and background channels.
• Metrics include delay spread and angle spread.
