Abstract (en)

[origin: WO9922531A2] The inventive base station for a mobile communication system with TDMA components contains a signal processing device (SP) to prepare useful information (ni) and organisational information (oi) for transmission via a radio interface. The signal processing device (SP) is controlled by a control device (SE) in such a way that the useful information (ni) is prepared for transmission in a frequency channel (FK1) of a first high frequency carrier (TRI) with TDMA components and the organisational information (oi) is prepared independently from the useful information (ni) for transmission in a frequency channel (FK2) of a second high frequency carrier (TR2) with TDMA components. The frequency channel of the first high frequency carrier has a larger band width than the frequency channel of the second high frequency channel. Separate transmission devices (UE1, UE2) modulate a transmission signal (tx2) for high frequency transmission of the organisational information using the second high frequency carrier and a transmission signal (tx1) for high frequency emission of useful information using the second high frequency carrier.
