Abstract: Available transfer capacity is apportioned efficiently by stations informing each other of their capacity needs by sending messages when necessary. The sent messages can contain information on priority and capacity requirement. Stations which receive the sent capacity requests release unrequired transfer capacity or transfer capacity which is not urgently required, so that the capacity can by used by a station in need. The corresponding information can also be transferred by other stations, e.g. by several hops.

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.

Abstract: The invention relates to a method for accessing stations (WT, AP, APTi) onto a common transfer medium, wherein said stations (WT, AP, APTi) share the common transfer medium with other stations. In order to apportion the available transfer capacity as efficiently as possible, said stations inform each other of their capacity needs by sending messages when necessary. The sent messages can contain information on priority and capacity requirement. Stations which receive the sent capacity requests release unrequired transfer capacity or transfer capacity which is not urgently required, so that said capacity can by used by a station in need. The corresponding information can also be transferred by other stations, e.g. by several hops.

Abstract: The invention relates to a method for the parallel transmission of identical data from a transmitter/receiver device to a plurality of terminals, said transmission at least partially proceeding via a radio connection. Common transmission capacities for a transmission of quality information regarding the transmission quality of the data are provided to the transmitter/receiver device in this radio connection for the purpose of transmission by a plurality of terminals.

Abstract: 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.
