cellular operators as a complementarytool to augment their service offering
› Adapt initial/channel access, scheduling/HARQ,and mobility operations for unlicensedspectrum regulation & characteristics
– Reuse existing NR as much as possible
› Existing bands and potentially new bands– Preferred band is 5/6 GHz– Coexistence study for new bands
› Support diverse deployment cases– Carrier aggregation NR + NR-U– Dual connectivity LTE/NR + NR-U– Standalone NR-U

Vehicle-to-everything(3GPP V2X Phase 3) › Improved support for V2X services
– LTE-V2X enables day-1 safety
– NR-V2X is a complementary technology addressingnew use cases (e.g. platooning, advanced driving,sensor sharing) and tighter requirements
› Study NR design for V2X– Targeting a wider range of frequencies (up to 52.6
GHz), with initial focus on FR1 frequencies.
– Cellular (Uu) enhancements for high mobility scenariosand improved efficiency when delivering ITS traffic
– Sensing-based resource allocation scheme mostlydesigned for aperiodic transmissions.
– Some unicast/groupcast features such as linkadaptation, power control, etc.
› Ensure optimal coexistence
