The invention relates to a method for the synchronous transmission of messages (D1, D2). The messages (D1, D2) are composed of a sequence (C1, C2) of information bits and are transmitted in the form of sub-symbols (SU1, SU2) by means of a synchronous multi-carrier transmission method. Said sub-symbols (SU1, SU2) are composed of individually modulated carrier signals (TA1, TA2), wherein the carrier signals (TA1, TA2) are associated with different sub-channels (B) of a transmission channel (UE). The first carrier signals (TA1, TA2) that are used for forming a first sub-symbol (SU1) are arranged in a frequency time range for the transmission such that a protection interval (Tg) is created within a signal transmission period (T). The protection interval (Tg) is then used for transmitting at least one second sub-symbol (SU2), wherein the at least second sub-symbol (SU2) is formed from second carrier signals (TA2) that differ from the first carrier signals (TA1) of the first sub-symbol (SU1). Said first carrier symbols (TA1) of the first sub-symbol (SU1) may optionally be partially overlapped in the time and/or frequency range by at least the second carrier signals (TA2) of the at least second sub-symbol. The method ideally and simply combines an increase in interference immunity for a transmission of messages (D1, D2) with good spectral efficiency that is provided by a synchronous transmission of messages (D1, D2) via a plurality of sub-channels (B) of a transmission channel (UE).
