User equipment and method in a communications network

A wireless device configured to be served by a serving carrier and configured to make measurements of carriers, the wireless device configured to:

• perform, during a first time period, at least one of a first measurement of a first carrier having lower priority than a priority of the serving carrier and a second measurement of a second carrier having a higher priority than the priority of the serving carrier, the first time period being a subset of an available time for performing measurements;
• and
• perform a third measurement of a closed subscriber group (CSG) cell during a second time period remaining in the available time, the second time period being exclusive of the first time period.

A method performed by a network node for configuring a wireless device served by a serving carrier to perform measurements of carriers, the measurements including, during a first time period, at least one of a first measurement of a first carrier having lower priority than a priority of the serving carrier and a second measurement of a second carrier having a higher priority than the priority of the serving carrier, the first time period being a subset of an available time for performing measurements, the measurements further including a third measurement of a closed subscriber group (CSG) cell during a second time period remaining in the available time, the second time period being exclusive of the first time period, the method comprising:

• generating a maximum second time period for performing at least the third measurement at the wireless device by scaling the second time period;
• and
• transmitting the maximum second time period to the wireless device.
