Various communication systems may benefit from relaxed performance requirements. For example, long term evolution (LTE), and in particular heterogeneous networks (HetNet) as well as small cell detection and discovery in small cell deployments in general, may benefit from relaxed performance requirements for offloading measurements. A method can include determining whether a user equipment is in active data transfer. The method can also include using a relaxed performance requirement with respect to a plurality of gap bursts when the user equipment is determined not to be in active data transfer.
