Creating asymmetric wireless communication by: Allocating a first plurality of frequency bands to a first transmission direction and at least one frequency band to an opposite transmission direction where all the frequency bands use the same FFT size. Dividing at least one of the frequency bands into sub-bands or slots. Creating an asymmetrical communication channel including at least one of: A whole number of the frequency bands in one direction and at least one of the sub-bands in the opposite direction. A first number of the sub-bands in one direction and a different number of the sub-bands in the opposite direction. At least one sub-band in one direction and at least one sub-band in the opposite direction having different size. And at least one frequency band and at least one sub-band in one direction and a different number of frequency bands and/or sub-bands in the opposite direction.
