1. A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, said transmitting apparatus comprising:

  • a frame former that forms frames of said frame structure, each frame comprising at least two signaling patterns adjacent to each other in a frequency direction and one or more data patterns following the at least two signaling patterns in a time direction in a time slot immediately succeeding a time slot in which the at least two signaling patterns are located, wherein each of the data patterns succeeding the at least two signaling patterns is respectively followed by further data patterns in succeeding time slots in the time direction, wherein all data patterns following each other in the time direction have a same frequency direction structure, each of the at least two signaling patterns and the one or more data patterns comprising a plurality of frequency carriers, that arranges signaling data in each of said at least two signaling patterns in a frame, and that arranges data and at least one pilot signal in said one or more data patterns in the frame, wherein a length of each of said one or more data patterns in the frequency direction is equal to or a multiple of a minimum data pattern length;

    a transformer that transforms said at least two signaling patterns and said one or more data patterns from the frequency domain into the time domain to generate a time domain transmission signal; and

    a transmitter that transmits said time domain transmission signal.
