A method in a network node capable of operating in discontinuous activity mode, the method comprising:

• receiving, from a wireless device, a measurement result of at least one of:

• or
• a measurement on a second set of a plurality of cells or carriers comprising a normal measurement group if the signal level of the serving cell at the wireless device is equal to or above the signal threshold;
• and
• performing an operational task using the received measurement result, and
• wherein the first set of the one or more cells or carriers of the reduced measurement group is less than the second set of the plurality of cells or carriers of the normal measurement group.
