The method and radio relays for time-rigid coupling

The invention relates to a method for time-rigid coupling a receiving and an associated transmission device of a radio relay for a transmission standard which changes at least one transmission parameters according to defined time intervals. For this purpose, a signal is received at a receiving device and first control information contained therein and contained therein a clock (10) is read out from the received signal. Then, the read-out control information (11) transmitted together with the read clock (10) from the receiving apparatus to the transmitting apparatus, wherein the control information (11) are transmitted in time so that a contained in the control information pattern (13) in time read out with the clock (10) coincide. The received signal is also transmitted to the transmitting device. Finally, the transmitted signal is sent by the transmission device according to the transmitted control information and time synchronization with the transmitted clock.
