Abstract
A transmission technique for transmitting signals on the basis of an OFDM/TDMA-system, wherein a plurality of subcarriers that are orthogonal to each other are allocated to a variable number of channels, each channel containing a variable number of subcarriers depending On the information to be transmitted. For transmission in a GSM-system having a constant number of predetermined GSM-frequency channels and a constant number of predetermined GSM-timeslots being grouped in GSM-frames, the number of subcarriers allocated to each of the GSM-frequency channels is such that a multiple of the resulting OFDM/TDMA-timeslot matches with one (or a multiple of One) GSM-timeslot.
