Abstract:
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 configured to form frames of said frame structure, each frame including at least two signaling patterns adjacent to each other in the frequency direction and at least two data patterns following the at least two signaling patterns in the 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 signaling patterns is respectively followed by further data patterns in succeeding time slots in the time direction, all data patterns following each other in the time direction have a same frequency direction structure, and each of the at least two signaling patterns and the data patterns include a plurality of frequency carriers; a signaling mapper configured to map signaling data on the frequency carriers of each of said at least two signaling patterns in a frame of said frames, each signaling pattern having a same length; a data mapper configured to map data on the frequency carriers of said at least two data patterns in a frame of said frames; a transformer configured to transform said signaling patterns and said data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal; and a transmitter configured to transmit said time domain transmission signal.
