Abstract  Abstract

PROBLEM TO BE SOLVED: To avoid reduction of the system through-put due to application of PHICH.

SOLUTION: A communication device has PHICH reception means and retransmission control means. In the PHICH reception means when PHICH (Physical HARQ Indicator Channel) containing ACK or NACK transmitted from another communication device is received PHICH is not received in a communication unit for monitoring Scell(Secondary cell) received in a Non cross carrier scheduling (Non cross carrier scheduling) by a self-device and PHICH is received in a communication unit for monitoring Pcell (Primary cell) received in the Non cross carrier scheduling(Non cross carrier scheduling) by the self-device. On the basis of the received PHICH and allocation control information the retransmission control means performs the control as to whether retransmission to the other communication device is performed or not.
