A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, each frame including at least one signalling pattern and one or more data patterns, said transmitting apparatus including frame forming means for arranging first signalling data in the at least one signalling pattern in a frame, and adapted to arrange data in the one or more data patterns in a frame, whereby the data of the one or more data patterns are arranged in data frames, each data frame comprising second signalling data and content data, transforming means for transforming the at least one signalling pattern and the one or more data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal, and transmitting means for transmitting the time domain transmission signal.
