Section: 16.18.3 Height-based Reporting for Aerial UE Communication
Content: An Aerial UE can be configured with height-dependent, event-based measurement reporting (i.e., eventH1 and eventH2 as defined in TS 38.331[ NR; Radio Resource Control (RRC); Protocol specification ]  [12]). An Aerial UE sends a measurement report when its altitude becomes higher or lower than configured threshold. The UE includes its height and location information in the measurement report if configured to do so by NG-RAN. RSRP/RSRQ measurement results are always reported when height reporting is configured. The Aerial UE can also be configured to trigger measurement reporting only when both a height-dependent condition and a RSRP/RSRQ/SINR-based condition are met (i.e., eventA3H1, eventA3H2, eventA4H1, eventA4H2, eventA5H1 and eventA5H2 in TS 38.331[ NR; Radio Resource Control (RRC); Protocol specification ]  [12], commonly denoted as eventAxHy). For the content of eventAxHy measurement report, the same rules as described above for eventH1 and eventH2 apply.
