ABSTRACT:
In a radio communications network, transmission time is divided into a succession of frames for conducting data communications with subscriber stations located within a coverage area of two central stations of the network. In a first broadcast phase of each frame, a first central station transmits first frame format information, which defines a first downlink phase of the frame and a first uplink phase. In the same frame, a second central station transmits, on the same frequency, second frame format information, which defines a second downlink phase and a second uplink phase for the communication of subscriber stations with the second central station, whereby the phases with a frame do not overlap.
