Measurement handling is of interest in a user equipment (UE) in connected mode, with the UE being configured with multiple downlink component carriers (CCs). The UE evaluates the signal quality of a specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers.
