Abstract: Disclosed is a method and corresponding system for transmitting a determined altitude of a user equipment device located in a building. One embodiment takes the form of a method. The method may involve determining a first distance between a node at a known position in a building and a user equipment device located in the building based on known planar coordinates of the node and known planar coordinates of the user equipment device. The method may further involve determining a second distance between the user equipment device and the node based on propagation of at least one signal between the node and the user equipment device. The method may further involve determining an altitude of the user equipment device based on the determined first distance, the determined second distance, and a known altitude of the node. And the method may involve transmitting the determined altitude of the user equipment device.
