A method performed by a wireless device for idle mode measurements while the wireless device is in an idle or inactive state, the method comprising: • obtaining (600 and/or 602), on a first cell, first measurement configurations for a first set of carriers comprising: - one or more overlapping carriers, wherein an overlapping carrier is a carrier that is configured for both idle mode measurements and inter-frequency mobility measurements, - one or more non-overlapping carriers, wherein a non-overlapping carrier is a carrier that is configured for idle mode measurements but not for inter-frequency mobility measurements, or - both one or more overlapping carriers and one or more non-overlapping carriers; • transitioning to a dormant state; and • while in the dormant state: - performing a cell re-selection from the first cell to a second cell while an idle mode measurement duration timer is running; - obtaining, from the second cell, second measurement configurations for a second set of carriers comprising one or more overlapping carriers, one or more non-overlapping carriers, or both one or more overlapping carriers and one or more non-overlapping carriers; characterized by - performing one or more actions in response to one or more mismatches between the first measurement configurations and the second measurement configurations, wherein - the one or more actions comprise replacing a measurement configuration from among the first measurement configurations with a mismatching measurement configuration from among the second measurement configurations, and - keeping a measurement configuration from among the first measurement configurations and ignoring the mismatching measurement configuration from among the second measurement configurations. • obtaining (600 and/or 602), on a first cell, first measurement configurations for a first set of carriers comprising: - one or more overlapping carriers, wherein an overlapping carrier is a carrier that is configured for both idle mode measurements and inter-frequency mobility measurements, - one or more non-overlapping carriers, wherein a non-overlapping carrier is a carrier that is configured for idle mode measurements but not for inter-frequency mobility measurements, or - both one or more overlapping carriers and one or more non-overlapping carriers; - one or more overlapping carriers, wherein an overlapping carrier is a carrier that is configured for both idle mode measurements and inter-frequency mobility measurements, - one or more non-overlapping carriers, wherein a non-overlapping carrier is a carrier that is configured for idle mode measurements but not for inter-frequency mobility measurements, or - both one or more overlapping carriers and one or more non-overlapping carriers; • transitioning to a dormant state; and • while in the dormant state: - performing a cell re-selection from the first cell to a second cell while an idle mode measurement duration timer is running; - obtaining, from the second cell, second measurement configurations for a second set of carriers comprising one or more overlapping carriers, one or more non-overlapping carriers, or both one or more overlapping carriers and one or more non-overlapping carriers; characterized by - performing one or more actions in response to one or more mismatches between the first measurement configurations and the second measurement configurations, wherein - the one or more actions comprise replacing a measurement configuration from among the first measurement configurations with a mismatching measurement configuration from among the second measurement configurations, and - keeping a measurement configuration from among the first measurement configurations and ignoring the mismatching measurement configuration from among the second measurement configurations. - performing a cell re-selection from the first cell to a second cell while an idle mode measurement duration timer is running; - obtaining, from the second cell, second measurement configurations for a second set of carriers comprising one or more overlapping carriers, one or more non-overlapping carriers, or both one or more overlapping carriers and one or more non-overlapping carriers; - performing one or more actions in response to one or more mismatches between the first measurement configurations and the second measurement configurations, wherein - the one or more actions comprise replacing a measurement configuration from among the first measurement configurations with a mismatching measurement configuration from among the second measurement configurations, and - keeping a measurement configuration from among the first measurement configurations and ignoring the mismatching measurement configuration from among the second measurement configurations.
