Abstract: A radio device applies a carrier frequency for transmission of data between the radio device and a base station of a cellular network. Further, the radio device configures a measurement time interval in which the radio device temporarily switches from the transmission of data to receiving at least one broadcast signal conveying system information from the base station. Based on the received at least one broadcast signal, the radio device estimates an offset of the carrier frequency as applied by the radio device to a frequency of a carrier signal as received from the base station.
