Abstract
A method synchronizes plural terminal communication systems and a counterpart communication station connected via a radio link within a multi-standard wireless communication system, wherein a counterpart transmission signal is transmitted from said counterpart communication station to the corresponding terminal communication system. A common reference clock signal is generated and supplied to a signal generation unit within said terminal communication system, wherein each terminal communication system comprises a conversion ratio unit having a conversion ratio. An accurate frequency datum is derived from each counterpart transmission signal in the terminal communication systems and a frequency control signal is determined from said accurate frequency datum. A synchronization between said terminal communication stations and counterpart communication station is obtained by adjusting the frequency of the common reference clock signal and/or the conversion ratio of said conversion ratio units according to the frequency control signal.
