To enable CQI information to notify the transmission side to be compressed with efficiency, while minimizing the effect on scheduling on the transmission side, provided are reception sections 30 to 34 that receive signals transmitted using a plurality of subcarriers, a reception quality calculating section 40 which divides a frequency band associated with the plurality of subcarriers, and calculates reception quality information indicative of reception quality of the received signals based on an information amount determined for each divided frequency band, and transmission sections 10 to 17 that transmit the calculated reception quality information to a transmission source of the signals.

L'invention concerne un dispositif de communication qui peut réduire l'effet du côté transmission sur la planification et qui peut effectuer efficacement la compression d'informations d'indication de qualité de canal (CQI) rapportées au côté transmission. Le dispositif de communication comprend des unités de réception (30 à 34) qui reçoivent un signal transmis par l'utilisation d'une pluralité de sous-porteuses ; une unité de calcul de qualité de réception (40) qui divise une bande de fréquence correspondant aux sous-porteuses et qui calcule des informations de qualité de réception indiquant la qualité de réception du signal reçu en fonction de la quantité d'informations déterminée pour chacune des bandes de fréquence divisées ; et des unités de transmission (10 à 17) qui transmettent les informations de qualité de réception calculées vers la source de transmission du signal.
