Abstract
A wireless communication base station device capable of improving the reception quality of the MBMS data of UE without wasting wireless resources even if an error occurs in the MBMS data transmitted from an eNB when distributing the MBMS via a wireless access network composed of the eNB and an RS. In the device, a wireless quality determining section () outputs reception quality determination information indicating the reception quality between the UE and the device determined on the basis of a CQI included in the NACK signal received from the UE to a retransmission determining section (). A retransmission data determining section () of the retransmission determining section () determines MBMS data to be retransmitted from the device and retransmission data (FEC encoding ratio of the MBMS data) to be retransmitted from the RS on the basis of the reception quality determination information inputted from the wireless quality determining section (). The retransmission data determining section () notifies the RS of a request to relay the data including the FEC encoding ratio of the retransmission data to be retransmitted from the RS.
