The disclosure relates to a method in a network node of a communications system, for enabling measurements performed by a wireless device, when MBSFN subframes are configured in the system. The method comprises determining (610) a measurement resource restriction pattern indicating subframes for performing at least one measurement for at least one cell, wherein the indicated subframes are non-MBSFN subframes comprising subframes that are not MBSFN configurable. The method also comprises transmitting (620) the measurement resource restriction pattern to the wireless device, for enabling measurements for the at least one cell according to the pattern. The disclosure also relates to a method in a wireless device for performing measurements when MBSFN subframes are configured in the system.
