Abstract  Abstract

The channel quality information requests and reports when intermittently transmitting the reference signal are suppressed from concentrating on a specific resource in the time direction, and throughput degradation is prevented. The transmission apparatus eNB transmits the instruction of the CSI request to each reception apparatus UE1 and UE2 using the PDCCH in a subframe simultaneously with or earlier than the reference signal CSI-RS and distributed for each reception apparatus. To do. Receiving apparatuses UE1 and UE2 detect a CSI request from the transmitting apparatus, and calculate CSI from the CSI-RS channel estimation value received thereafter. Then, the CSI report subframe of its own device is specified from the CSI report interval information of a predetermined time interval notified in advance, the subframe in which the CSI request is detected, and the transmission timing of the CSI-RS, and the CSI report subframe is determined at this timing. A feedback signal including a report value is transmitted using PUSCH.
