Measurement event evaluation is of interest in a user equipment (UE) configured with multiple downlink component carriers (CCs). The UE performs measurements of a neighbor and a specific one of the configured CCs, being used as a reference CC. The UE evaluates, based on the measurements of the neighbor and the reference CC, being a specific one of the configured CCs, an evaluation criterion for triggering a measurement report from the UE. In this way, the number of event evaluations and measurement reports can be reduced, since a specific reference CC is used for the purpose of measurement event evaluation in a scenario when the UE is configured with multiple CCs.
