In an embodiment, an apparatus measures, via a first directional receive antenna array and a second directional receive antenna array that are each coupled to an apparatus, one or more signals that are transmitted by one or more transmitters of the UE. The first and second directional receive antenna arrays are oriented at different directions. The apparatus determines first and second representative values for the first and second directional receive antenna arrays, respectively based on some or all of the measurements. The apparatus determines whether the UE is within a given region based on the first and second representative values.
