Abstract: Aspects of the subject disclosure may include, for example, receiving information regarding an aerial UE that is communicatively coupled with a network node, obtaining data associated with the network node that correlates altitude values with signal quality levels and/or probabilities of connectivity disruption, determining a conservative height threshold and an aggressive height threshold for the network node based on the data, wherein the conservative threshold is lower than the aggressive threshold, analyzing the information regarding the aerial UE, based on the analyzing, selecting either the conservative threshold or the aggressive threshold for the network node to use for the aerial UE, resulting in a selected height threshold, wherein the selected height threshold affects a frequency or likelihood of height-based trigger events for the aerial UE, and causing the network node to include the selected threshold in height-based measurement report settings for the aerial UE. Other embodiments are disclosed.

Abstract: The technologies described herein are generally directed to generating a propagation model based on sampling by user equipment in idle mode in a fifth generation (5G) network or other next generation networks. An example method can include, based on a first location in a geographic area of a signal measurement measured by a user equipment in an idle mode, and a transmission location of the signal, estimating an estimated first path loss value. The method can further include, based on the estimated first path loss value and a second path loss value of a second carrier signal received from the carrier signal source, determining an antenna pattern of the carrier signal source. Further, the method can include based on the antenna pattern, generating a propagation model for the carrier signal source.
