Claim:
1. A method of assigning transmit power in a multiple-input-multiple-output (MIMO) two-stream transmission, the method comprising: receiving a first symbol stream associated with a plurality of subcarriers in accordance with constellation information contained in a first tonemap, the first tonemap including first information indicating subcarriers of the plurality of subcarriers that are not used for transmitting data; receiving a second symbol stream associated with the plurality of subcarriers in accordance with constellation information in a second tone map, the second tonemap including second information indicating subcarriers of the plurality of subcarriers that are not used for transmitting data; reallocating, by the circuitry according to the first tonemap when a subcarrier for the first symbol stream is not used for transmitting data and the corresponding subcarrier for the second symbol stream is used for transmitting data, all of the transmit power of the subcarrier of the first symbol stream to the corresponding subcarrier of the second symbol stream; and reallocating, by the circuitry according to the second tonemap when a corresponding subcarrier for the second symbol stream is not used for transmitting data and the subcarrier for the first symbol stream is used for transmitting data, all of the transmit power of the subcarrier of the second symbol stream to the subcarrier of the first symbol stream.
