ABSTRACT:
Instead of transmitting signals between two individual switching circuits in a communication device via separate paths for the receive and send mode, the signals are transmitted via a common transmission path. Non-overlapping time slots are respectively provided for transmission and reception. The inventive method is particularly suitable for radiotelephone devices, especially for mobile radio telephones.
