ABSTRACT:
The transmission points are determined in time for an asynchronous transfer of information (speech/data) in relation to a synchronous information transfer so that the asynchronous transmission does not coincide with the synchronous reception. The asynchronous and the synchronous reception take place at short distances, e.g., less than 200 m, and the terminals are arranged close to each other and can therefore disturb each other. The frequency band of one terminal is also close to the frequency band of the second terminal. In the asynchronous terminal, the relative times are stored for transmission and reception regarding the synchronous terminal. A procedure is stored in the asynchronous terminal, which, during a predetermined time interval before each synchronous transmission, detects if and when transmission occurs from the synchronous terminal and if the detected signal power exceeds a predetermined threshold value. If the levels in the previous step exceed the predetermined threshold value, the transmission from the asynchronous terminal is timed so that is does not disturb the communication of the synchronous terminal by not coinciding with the reception at the synchronous terminal.
