In a radio communications network, the 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 (AP1) transmits first frame format information (BCH), which defines a first downlink phase of the frame (DL phase) and a first uplink phase (UL phase). In the same frame, a second central station transmits, on the same frequency, second frame format information (BCH), which defines a second downlink phase and a second uplink phase for the communication of subscriber stations (MS) with the second central station (AP2), whereby the phases within a frame do not overlap.
