6G

End-to-end ns-3.43 simulator for 6G non-terrestrial networks. Five integrated modules: 3GPP Rel-17 TTE-aware Conditional Handover, O-RAN Near-RT + Space RIC with 13 xApps, sub-THz/THz physics (HITRAN, UM-MIMO, RIS, ISAC), ns3-ai fork with federated learning, NTN traffic — over SNS3, mmWave-NR, 3GPP TR 38.811. LEO/MEO/GEO.

Sub-THz/THz physics module for ns-3.43 NTN scenarios — 100 GHz to 1 THz. HITRAN-2020 line-by-line absorption, ITU-R P.835/676/618/838 channels, D-band ISL, UM-MIMO up to 16384 elements, RIS quantisation sweep, ISAC CRB, EKF beam tracker, LEO-pass demos. Cross-validated against ITU-R P.676-13 and am. GPL-2.0.

Group-level README and docs

3GPP Release-17 Conditional Handover framework for 6G LEO satellite networks in ns-3.43. Implements a novel TTE-aware (Time to-Exit) trigger plus three reference baselines (A3, time-based, location-only) with SGP4 propagator, Walker-Star generator, mmWave+sat channel adaptor and a 5-seed Monte-Carlo harness. GPL-2.0.
