Abstract: Positioning reference signals are transmitted in a downlink direction from base stations (200) of a wireless communication network to a wireless communication device (100) or in an uplink direction from the wireless communication device (100) to base stations (200) of the wireless communication network. According to a frequency hop pattern, a radio interface of the wireless communication device is switched between multiple different frequency ranges. In this way, the wireless communication device (100) can receive the downlink positioning reference signals on multiple different frequencies defined by the frequency hop pattern or send the uplink positioning reference signals on multiple different frequencies defined by the frequency hop pattern.

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.
