Abstract
The invention relates to a method for supporting cell change between frequency layers. The method is performed in a UE and/or a RN node of a wireless communication network deploying two frequency layers. The RN node serves a UE in a cell of a first of the two frequency layers. The UE is configured to perform measurements on the first frequency layer, and to exclude measurements on a second of the two frequency layers. The method comprises receiving () measurement results from the UE, for measurements performed on a cell of the first frequency layer, determining () a location of the UE based on the measurement results, assessing () a coverage of a target cell of the second frequency layer based on the location and a coverage map for the two frequency layers, and determining () whether to change to the target cell based on the assessment.
