Abstract
The transition to 6G has driven significant updates to the 3GPP channel model, particularly in modeling UE antennas and user-induced blockage for handheld devices. The 3GPP Rel.19 revision of TR 38.901 introduces a more realistic framework that captures directive antenna patterns, practical antenna placements, polarization effects, and element-specific blockage. These updates are based on high-fidelity simulations and measurements of a reference smartphone across multiple frequency ranges. By aligning link- and system-level simulations with real-world device behavior, the new model enables more accurate evaluation of 6G technologies and supports consistent performance assessment across industry and research.
