Abstract

A network device determines localization constraint(s) for an expected vertical range over which a UE may be positioned. The network device estimates vertical position of the UE. The network device compares the estimated vertical position with the localization constraint(s). The network device performs different actions depending on whether the estimated vertical position is within or outside the localization constraint(s). The network device may be the UE 110, a location server (e.g., LMF), or an LMC as implemented by the RAN node.

First claim

1 .- 28 . (canceled)

29 . A device comprising:
a processor; and a non-transitory computer-readable medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform the following operations: determining one or more localization constraints for an expected vertical range over which a user equipment may be positioned; estimating vertical position with the one or more localization constraints; and performing different actions depending on whether the estimated vertical position is within or outside the one or more localization constraints.
