Patent ID: 7020471

Claim:
A method for data communication with subscriber stations in a radio communications network in which data transmission is subdivided into a sequence of frames, comprising: transmitting from a first central station first frame format information in a first broadcast phase of each frame, the first frame format information defining a first downlink phase of the frame, in which payload data is transmitted from the first central station to the subscriber stations, and a first uplink phase, in which the subscriber stations are allowed to transmit to the first central station; transmitting from at least one second central station second frame format information in at least one second broadcast phase in each frame, the second frame format information defining a second downlink phase and a second uplink phase for communication from subscriber stations to the second central station; and allocating a continuous time interval in one frame to each of the first and second central stations by a control unit as a function of transmission requirements received from the first and second central stations, where the continuous time interval is subdivided into an unlink phase and a downlink chase independently by each of the first and second central stations.
