摘要：
To efficiently compress the information amount for feedback when a communication apparatus sends back a result of performing discrete cosine transform on the reception quality information to a communication apparatus of a communicating destination. In a communication apparatus for transmitting feedback information generated based on a plurality of reception quality information to a communicating destination apparatus, the feedback information is a result of performing discrete cosine transform on the plurality of reception quality information, and performing respective different quantization on signal components of at least a group of samples among signal components of a plurality of samples obtained by the discrete cosine transform.
