Abstract

Disclosed is a method comprising obtaining a first set of measurement information associated with a reference signal transmitted from a set of positioning reference units; selecting a subset of positioning reference units from the set of positioning reference units, wherein the selection is based at least on determining that the reference signal transmitted per positioning reference unit of the subset of positioning reference units is measured by a same set of network nodes that measured a reference signal transmitted from a target user device; and refining a location estimate of the target user device based at least on a subset of measurement information from the first set of measurement information, wherein the subset of measurement information is associated with the subset of positioning reference units.
