The present invention relates to a transmitting apparatus (54) for transmitting signals in a multi carrier system on the basis of a frame structure, each frame comprising at least two signalling patterns adjacent to each other in the frequency direction and at least one data pattern, said transmitting apparatus comprising frame forming means (59) adapted to arrange signalling data and pilot signals in each of said at least two signalling patterns in a frame, each signalling pattern having the same length, and to arrange data on frequency carriers of said at least one data pattern in a frame, transforming means (60) adapted to transform said signalling patterns and said data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal, and transmitting means (61) adapted to transmit said time domain transmission signal. The present invention further relates to a corresponding transmitting method, a frame pattern for a multi carrier system and a receiving apparatus and method as well as a transmitting and receiving system and method.
