Abstract

In order to compatibly adapt a wireless telecommunication system with a CDMA, FDMA and TDMA multiple access component, particularly a hybrid “JD-CDMA” telecommunication system with respect to multiple access methods, to a GSM-specific/DECT-specific (micro-cell, macro-cell and/or Pico cell-specific) telecommunication system with respect to the air interface, signaling information fashioned as “stealing flag” for distinguishing between payload and signaling channels are first arranged such in a provided time slot structure that an asymmetrical division of the time slot data arises with respect to a training data block (midamble) of the time slot structure and, second, the transmission time duration for the provided time slot structure of a data element fashioned as “chip” and contained in the time slot structure is dimensioned such that this is a multiple of a predetermined clock frequency—for example, GSM/DECT-specific clock frequency—covering the numerical range from 5 through 7.
