Estimating the term…
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.
A method for data communication with subscriber stations (MT) in a radio communications network wherein the time is subdivided into a sequence of frames, in which a first central station (AP1) transmits first frame format information (BCH, FCH and ACH) in a first broadcast phase of each frame, which information defines a first downlink phase of the frame (DL phase), in which payload data is transmitted from the first central station (AP1) to the subscriber stations (MT), and a first uplink phase (UL phase), in which the subscriber stations (MT) are allowed to transmit to the first central station (AP1), and in which each frame has at least one second broadcast phase in which at least one second central station (AP2) transmits second frame format information (BCH, FCH and ACH), which defines a second downlink phase (DL phase) and a second uplink phase (UL phase) for communication from subscriber stations to the second central station (AP2), with the uplink and downlink phases being allocated to the central stations (AP1, AP2) by a control unit (APC) as a function of a respectively signaled transmission requirement.
The method as claimed in one of the preceding claims, characterized in that each central station (AP1, AP2) is allocated a continuous time interval in one frame, which continuous time interval comprises a broadcast phase, an uplink phase and a downlink phase for that station.
A radio communications network having a number of central stations (AP1, AP2) for data communication with subscriber stations (MT), characterized in that at least two central stations (AP1, AP2), which use the same frequency, are connected to one control unit (APC), which allocates separate time intervals for the uplink and downlink phases to each of them within one transmission frame, as a function of a respectively signaled transmission requirement.
