Abstract: There is provided method comprising: transmitting by a first entity a first carrier signal of a plurality of carrier signals, the first carrier signal being centered at a first frequency offset from a first channel raster point by an amount which is greater than 0 and less than a first threshold, wherein a second carrier signal is adjacent the first carrier signal and centered at a second frequency at or within a second threshold of a second channel raster, both the first carrier signal and the second carrier signal comprising a plurality of subcarriers of a defined bandwidth, and the first frequency and the second frequency differ by an amount substantially equal to a multiple of the defined bandwidth.
