Abstract  Abstract

To avoid lowering system throughput due to PHICH operation.SOLUTION: A communication device includes a transmission unit that transmits a physical HARQ indicator channel (PHICH) including ACK or NACK to a terminal device at the time of carrier aggregation by a primary cell (Pcell) and does not perform the transmission by a secondary cell (Scell) a reception unit that receives retransmission data based on PHICH transmitted by the Pcell and uplink allocation control information (UL grant). In a retransmission control method, at the time of carrier aggregation, the PHICH including ACK or NACK is transmitted to the terminal device by the Pcell, and is not transmitted by the Scell, and in the terminal device, retransmission data based on the PHICH transmitted by the Pcell and the uplink allocation control information is received.SELECTED DRAWING: Figure 5
