Abstract: It is described a communication end device comprising (a) a radio transceiver comprising a receiver for receiving radio signals from a transmitting network entity of a cellular telecommunication network and a transmitter (110, 120, 130) for transmitting radio signals to a receiving network entity of the cellular telecommunication network, (b) a further receiver (140) for receiving a further radio signal, and (c) a control circuit (150, 162, 164), which is coupled to the radio transceiver and to the further receiver (140). The control circuit (150, 162, 164) is configured for generating a control signal for controlling the operation of the further receiver (140). Thereby, the control signal is based on a synchronization signal being related to a time dependent transmission scheme of the transmitter (110, 120, 130) and on an information about the current operational state of the radio transceiver.

Abstract: An apparatus and a method provide synchronization of an output signal to a synchronization information. The synchronization is accomplished by providing coupling of a correction control information that controls a signal generator, e.g. a phase locked loop arrangement or a direct digital synthesis arrangement, to its exact frequency to a frequency conversion unit that converts an uncorrected reference frequency to a correct or exact reference frequency. Thereby, the uncorrected reference frequency for the signal generator can be provided by a simple crystal oscillator without any frequency controller. The setting of the signal generator and the frequency conversion unit can be done in a predetermined sequence which enables a user equipment to synchronize its reference frequency to the synchronization information emitted by a communication network.

Abstract: The present invention relates to an apparatus and method for providing synchronization of an output signal to a synchronization information. The synchronization is accomplished by providing coupling of a correction control information that controls a signal generating means, e.g. a phase locked loop arrangement (30) or a direct digital synthesis arrangement, to its exact frequency to a frequency conversion unit (90) that converts an uncorrected reference frequency to a correct or exact reference frequency. Thereby, the uncorrected reference frequency for the signal generating means (30) can be provided by a simple crystal oscillator (2) without any means for frequency control. The setting of the signal generating means (30) and the frequency conversion unit (90) can be done in a predetermined sequence which enables a user equipment to synchronize its reference frequency to the synchronization information emitted by a communication network.

Abstract: In a method for synchronizing a mobile station with the base station in a mobile communication system, a reference-frequency oscillator is re-adjusted. To enable an inexpensive reference-frequency oscillator of simple construction to be used, the frequency variations resulting from a change in the temperature of the mobile station and a change in its location are determined and/or predicted separately. When the frequency variations are large, the mobile station is synchronized with the base station more frequently than when they are small.
