Abstract
Provided are a mobile terminal apparatus, a radio base station apparatus and a radio communication method, capable of saving PHICH resources enough and realizing effective retransmission control of uplink SU-MIMO. The radio communication method of the present invention is characterized in that a radio base station apparatus receives signals of plural codewords, when there is an error in each of the codewords, generates a one-bit negative response physical HARQ indicator channel signal and transmits the physical HARQ indicator channel signal, and a mobile terminal apparatus receives the physical HARQ indicator channel signal and transmits retransmission signals of all the codewords to the radio base station apparatus based on the negative response physical HARQ indicator channel signal.
