Patent ID: 8804479

Claim:
A transmitting apparatus for transmitting signals in a multi carrier system on the basis of a frame structure, said transmitting apparatus comprising: frame former circuitry that forms frames of said frame structure, each frame comprising at least two signaling patterns in a frequency direction and one or more data patterns following the at least two signaling patterns in a time direction, wherein: each of the one or more data patterns is followed by further data patterns in the time direction, 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 and further data patterns comprise a plurality of frequency carriers, the frame former circuitry arranges signaling data in each of said at least two signaling patterns and arranges data in said one or more and further data patterns, scrambling circuitry that scrambles the signaling data by use of a unique scrambling sequence, transformer circuitry that transforms said at least two signaling patterns and said one or more and further data patterns from the frequency domain into the time domain in order to generate a time domain transmission signal, and a transmitter that transmits said time domain transmission signal.
