Abstract  Abstract

PROBLEM TO BE SOLVED: To avoid deterioration in a system throughput due to an operation of a PHICH.

SOLUTION: A communication device includes: a PHICH (Physical HARQ Indicator Channel) receiving unit that does not receive a PHICH at a secondary cell (Scell) but receives the PHICH at a primary cell (Pcell) when receiving the PHICH including an ACK or a NACK transmitted by another communication device during carrier aggregation; and a retransmission control unit that performs control of whether to retransmit to the other communication device on the basis of the received PHICH and allocation control information.
