A wireless device obtains information associated with N layers, which may be used for cell reselection. The information comprises which M layers out of the N layers are to be used for monitoring according to detection and measurement requirements for absolute priority reselection. The wireless device monitors layers, of any priority, only out of the M layers, when one or more first signal measurements on a serving cell are below or equal to a first threshold, or when one or more second signal measurements on the serving cell are below or equal to a second threshold. The wireless device monitors layers with a priority higher than a priority of the serving layer out of the N layers when the one or more first signal measurements are above the first threshold, and when the one or more second signal measurements are above the signal threshold.
