Patent ID: 7672685

Claim:
A transmission apparatus which uses a first channel through which data is transmitted and a second channel on which power control is performed to transmit said data, said transmission apparatus comprising: transmission power control means for controlling the transmission power of said second channel; training means for obtaining correlation information that correlates the reception quality of said first channel transmitted from a reception apparatus for receiving said data and the transmission power of said second channel; predicting means for obtaining a predicted value of the reception quality of said first channel using the transmission power of said second channel based on said correlation information; and transmission controlling means for controlling the transmission of said data through said first channel based on the predicted value of the reception quality of said first channel, wherein the predicted value is judged based on a predetermined threshold value correlated to a frequency of transmitted acknowledgements corresponding to said training means, and wherein the transmission controlling means increases the frequency that the reception quality of said first channel is transmitted from the reception apparatus when the predicted value is above the predetermined threshold value and decreases the frequency that the reception quality of the first channel is transmitted from the reception apparatus when the predicted value is below the predetermined threshold value, and wherein the reception quality is transmitted more frequently when the predicted value is above the predetermined threshold value.
