Asymmetric Bands Allocation In Downlink And Uplink Using The Same FFT Size

A method of asymmetric wireless communication comprising the steps of:

• allocating a first frequency band to a first network device for transmitting information, and a portion of a second frequency band for receiving information;
• and
• allocating a third frequency band to a second network device for transmitting information, and another portion of said second frequency band for receiving information;
• wherein said first network device and said second network device use same FFT size for said first frequency band, said second frequency band and said third frequency band.

A wireless communication device for asymmetrical wireless communication, said wireless communication device comprising:

• a receiver module for receiving communication transmission;
• and
• a transmission module for transmitting communication transmission;
• wherein at least one of:
• said receiver module is operative to use a sub-band to receive said communication transmission;
• and
• said transmission module is operative to use a sub-band to transmit said communication transmission;
• and
• wherein said wireless communication device is allocated at least one of:
• a whole number of frequency bands in one direction and at least one sub-band in the opposite direction;
• a first number of sub-bands in one direction and a different number of sub-bands in the opposite direction;
• at least one sub-band in one direction and at least one sub-band in the opposite direction wherein said sub-bands in different directions have a different size;
• and
• at least one frequency band and at least one sub-band in one direction and a different number of at least one of frequency bands and sub-bands in the opposite direction;
• wherein said sub-bands are portions of a frequency band and all said frequency bands have a same width and use a same FFT size.
