Zusammenfassung:In order to provide TDD telecommunications systems which have an improved performance and/or an improved spectral efficiency compared to known TDD systems, such as, for example, the DECT system, the invention provides that a time-slot pair of time-slots (ZS'1...ZS'8), a "Downlink" time slot (ZSDOWN) and an "Uplink" time-slot (ZSUP), is selected in the TDD mode for each telecommunications connection between the mobile transmitting/receiving devices (MS1...MS5) and/or between the stationary transmitting/receiving devices (BTS1, BTS2). Said time-slot pair is selected in such a way that the distance (AS2...AS5) between the "Downlink" time-slot (ZSDOWN) and the "Uplink" time-slot (ZSUP), said time-slots being assigned to the same carrier frequency (FR1...FR12) or to different carrier frequencies (FR1...FR12), is a fractional part of the length of a time division multiplex frame (ZMR), whereby the distance is fixed or variable.
