    摘要: A transmission apparatus (1) obtains, for each transmission to a reception apparatus (2), information on a per-bit transmission of a transmission bit string, and controls a per-bit transmission condition for a current transmission bit string such that a per-bit transmission quality of the transmission bit string approaches evenly based on cumulative information on the transmissions up to the last transmission. This makes it possible to make the per-bit reception quality of a transmission bit string to approach evenly, thereby improving the communication capacity.
