16.18.1 General

NR connectivity for UEs capable of Aerial communication is supported via the following functionalities:

• Subscription-based Aerial UE identification and authorization, as specified in TS 23.502 [22], clause 5.2.3.3.1;
• Altitude reporting based on the measurement event(s) where the UE's altitude has crossed a network-configured reference altitude threshold;
• Altitude-dependent configurations which apply only to specific altitude regions;
• Interference detection based on a measurement reporting that is triggered when a configured number of cells (i.e. larger than one) fulfils the triggering criteria simultaneously;
• Signalling of flight path information from UE to NG-RAN and from the source gNB to target gNB during handover;
• Location information reporting, including UE's horizontal and vertical velocity;
• Transmitting of BRID and DAA messages via PC5 interface;
• Flight information reporting for Aerial UE as specified in TS 23.256 [60], clause 5.16.
