Abstract

A method relating to inter-frequency or inter Radio Access Technology (RAT) measurements (IFM) between a User Equipment (UE) and a mobile communications network (NW), and an apparatus for implementing the method, comprising operating, by a UE having a plurality of receiver branches (100) (1 10), detecting whether IFM is needed (120); and selecting, if IFM is needed, either to use dual antenna data reception for detecting data in compressed mode and performing IFM during gaps, or to use single antenna data reception mode (SADRM), using the second antenna for IFM based on the value of certain parameters (130).
