## Abstract

The disclosure of the present specification provides a method whereby a wireless device performs position measurement. The method may comprise the step of receiving information including settings for a narrowband positioning reference signal (NPRS). The information may include a list of carriers for the NPRS. The list of carriers may indicate physical resource blocks (PRBs) in which the NPRS is received. The method may comprise the step of determining that the geometry of the carriers is collocated.
