Patent ID: 8693413

Claim:
A radio communication terminal apparatus comprising: a receiving section that receives first scheduling information indicating a radio resource of a first multimedia broadcast/multicast service (MBMS) data from a radio communication base station apparatus, and receives the first MBMS data based on the first scheduling information; a radio quality measuring section that measures channel quality between the radio communication base station apparatus and the radio communication terminal apparatus, using a reference signal from the radio communication base station apparatus, and generates channel quality information (CQI) based on the measured channel quality; a detecting section that detects whether or not an error is present in the first MBMS data; and a transmitting section that determines whether or not to transmit a negative acknowledgement (NACK) signal including the CQI as a response signal; wherein: when the error is detected, the transmitting section does not transmit the response signal in the event that second scheduling information is received from a radio communication relay apparatus that can communicate with the radio communication terminal apparatus, the second scheduling information indicating a radio resource of second MBMS data transmitted from the radio communication relay apparatus, the transmitting section transmits the response signal in the event that the second scheduling information is not received from the radio communication relay apparatus, and the receiving section receives, in the event that the second scheduling information is received, the second MBMS data from the radio communication relay apparatus based on the second scheduling information, and receives, in the event that the second scheduling information is not received, retransmission data retransmitted from the radio communication base station apparatus or the radio communication relay apparatus.
