METHODS AND ARRANGEMENTS IN A TELECOMMUNICATION SYSTEM

摘要

The present invention relates to a method and a device for supporting positioning with a minimum of assistance data signalling. The method in the radio device that shall perform the positioning measurements comprises determining (440) a positioning reference signal pattern, based on a cell identity and a pre-defined mapping between the cell identity and the positioning reference signal pattern, and performing (450) positioning measurements based on the determined positioning reference signal pattern.
