A wireless device monitors a first radio link quality on a first plurality of reference signals of a bandwidth part of a cell in a non-power-saving state. The wireless device detects at least a first synchronization status based on the monitoring the first radio link quality. The wireless device receives a downlink control information indicating transitioning from the non-power-saving state to a power saving state. The wireless device monitors, based on the downlink control information, a second radio link quality on a second plurality of reference signals of the bandwidth part. The wireless device detects at least a second synchronization status based on the monitoring the second radio link quality.
