Document Type and Number:
WIPO Patent Application WO/2022/111953
Kind Code:
A3
Abstract:
A method (700) for estimating the location of a target UE using a positioning system comprising a set of N positioning reference nodes (PRNs). The method includes determining, from the set of N PRNs, a particular subset of PRNs that minimizes or maximizes an objective function, wherein the objective function is a function that is adapted to map information about a given subset of the N PRNs to an error value indicating a positioning error of the target UE. The method also includes using the determined particular subset of PRNs to estimate the location of the target UE.
