Section: 16.18 Support for Aerial UE Communication 16.18.1 General
Content: 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[ Procedures for the 5G System (5GS) ]  [22], clause 5.2.3.3.1; - height reporting based on the measurement event(s) where the UE's altitude has crossed a network-configured reference altitude threshold; - height-dependent configurations which apply only to specific height 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; - broadcasting of BRID and DAA messages via PC5 interface.
