    摘要: A half-duplex radio device (100) generates a repetitive transmission of an uplink message to a base station (150) of the cellular network. The radio device (100) splits the repetitive transmission of the uplink message into a sequence of multiple transmit periods and configures at least one measurement gap between the transmit periods. In the transmit periods, the radio device (100) sends the repetitive transmission to the base station. In the at least one measurement gap configured between the transmit periods, the radio device (100) temporarily switches to receiving at least one downlink signal from the base station (150). Based on the received at least one downlink signal, the radio device (100) estimates a frequency error of a reference frequency source of the radio device (100).

    摘要: 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 wire-less 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.
