Abstract:
1. A mobile terminal apparatus comprising: a receiving section configured to receive a physical HARQ indicator channel signal; a determining section configured to determine whether the physical HARQ indicator channel signal is a positive response or a negative response; a transmitting section configured to transmit retransmission signals for a plurality of codewords to a radio base station apparatus when the physical HARQ indicator channel signal is the negative response, and to suspend retransmission for the plurality of codewords to the radio base station apparatus when the physical HARQ indicator channel signal is determined to be the positive response, wherein the receiving section receives a downlink control channel signal, and the transmitting section transmits, when the downlink control channel signal includes an uplink grant that indicates retransmission for one codeword of the plurality of codewords, a retransmission signal of the one codeword of the plurality of codewords to the radio base station apparatus after suspending the retransmission for the plurality of codewords when the physical HARQ indicator channel signal is determined to be the positive response.
