Patent ID: 8457103

Claim:
A method, comprising: synchronizing a plurality of terminal communication systems and a counterpart communication station coupled via a radio link within a multi-standard wireless communication system, the synchronizing including: transmitting a counterpart transmission signal from the counterpart communication station to a corresponding terminal communication system of the plurality of terminal communication systems; generating a common reference clock signal; supplying the common reference clock signal to a signal generation unit within the terminal communication systems, wherein each terminal communication system comprises a conversion ratio unit having a respective conversion ratio; deriving a plurality of accurate frequency data from a plurality of respective counterpart transmission signals via a plurality of respective signal conversion units; deriving a plurality of frequency control signals from the respective accurate frequency data in the respective terminal communication systems; deriving a common frequency control signal from the frequency control signals by prioritizing the frequency control signal provided by the terminal communication system that is most accurate and selecting the prioritized frequency control signal as the common reference clock signal; controlling the frequency of the common reference clock signal via the common frequency control signal; and obtaining synchronization between the corresponding terminal communication system and the counterpart communication station, the obtaining including at least one of: adapting a frequency of the common reference clock signal according to the frequency control datum; and adapting the conversion ratio of the conversion ratio unit of the corresponding terminal communication system according to the frequency control datum.
