To generate notification information for improving accuracy of channel quality information reconstructed based on a difference in notifying using the difference in channel quality information between channels. A notification information generating apparatus 400 has a notification information table 401 that stores a plurality of difference-value candidate values each indicating a difference between two pieces of channel quality information as candidate values for the notification information, a reconstructing section 403 that generates a reconstruction value using the notification information generated based on the channel quality information of a first channel, and a selecting section 402 which receives the channel quality information of a second channel differing from the first channel, selects a single candidate value from the candidate values for the notification information based on the channel quality information of the second channel and the reconstruction value, and generates the notification information based on the selected candidate value.
