1. A method for operating a radio communication apparatus communicating with at least one other apparatus, the method comprising:utilizing a first frequency block of a set of frequency blocks,
wherein each frequency block comprises a center frequency and a predetermined number of sub bands used in communication; and
based on the at least one other apparatus interpreting a signal from a first of the sub bands of the first frequency block as noise, selecting a frequency offset of the first frequency block, wherein all of the sub bands of the at least-one adjacent frequency block partly overlap all of the sub bands of the first frequency block, and the frequency offset is smaller than a bandwidth of the first sub band,
wherein the center frequency of at least one adjacent frequency block is separated from the center frequency of the first frequency block by the frequency offset, and
wherein the frequency offset is between 30 to 60 Hz.
