9-speed planetary-gear automatic transmission

The invention relates to a method for operating a GSM mobile radio system, according to which at least one transmitter, which is allocated to a reference time generator, emits a signal including information concerning a reference time. The signal including the aforementioned information is received by the base stations. Each base station then synchronizes time slots of communications channels with reference to the reference time, said channels being made available via a radio interface between each respective base station and its allocated subscriber station.
