Abstract  Abstract

Provided are a wireless communication apparatus and a retransmission control method that avoid a decrease in system throughput due to the operation of PHICH. The PHICH receiving unit (206) determines whether the received signal in the PHICH region is ACK or NACK. At this time, the PHICH receiving unit (206) does not receive the PHICH in the subframe in which the terminal (200) monitors the E-PDCCH. When the signal output from the PHICH receiving unit (206) is NACK and no UL grant is detected, the control signal receiving unit (207) outputs a signal instructing retransmission to the signal allocation unit (210). When the UL grant is detected, the detected UL grant is output to the signal allocation unit (210). The signal allocation unit (210) maps the transmission signal according to the UL grant and the retransmission instruction signal, and transmits it from the wireless transmission unit (211).
