Abstract (en)
[origin: WO9859465A1] The invention relates to a method for transmitting data on a common medium between a center (133) and a plurality of subscribers (130, 131, 132), which is controlled by sending data packets for the center (133) to the subscribers (130, 131, 132) (downlink) and from the subscribers (130, 131, 132) to the center (133) (uplink). Downlink and uplink signaling data phases (2, 5; 30, 31; 40, 43, 45; 50, 53, 55, 57) are provided in signaling periods (1) of variable lengths in addition to user signal data phases (3, 4; 41, 42, 44, 46; 51, 52, 54, 56, 58). Said signaling data is used to organize uplink (10) and downlink (9) data transmission by transferring send request and allocating send time and optionally other information. Signaling data for subsequent data phases (42-46; 52-58) is contained in a downlink signaling data phase (9). Said subsequent data phases only begin after an intermediate data phase (41; 51), whereby the intermediate data phase is organized with an earlier downlink signaling data phase and is enhanced in terms of flexibility and dynamics by flexibly positioning the signaling data phases (30, 31, 5; 40, 43, 45; 50, 53, 55, 57) within a signaling period and by determining at least one preceding downlink signaling data phase and by activating a user signal data phase (44, 56) between an uplink signaling data phase (43, 55) and a downlink signaling data phase (45, 57).
