The quality of the transmission of HARQ-ACK/NACKs has to be higher in a MIMO multilayer communication system. In one embodiment, a wireless communication apparatus (10) includes a wireless communication unit (11) and a signal processing unit (12). The wireless communication unit (11) is configured to transmit plural multiple-input multiple-output (MIMO) layers using multiple antennas. The signal processing unit 12 is configured to map hybrid automatic repeat request (HARQ) responses onto some layers of the MIMO layers with a relatively high modulation and coding scheme (MCS), so that the HARQ responses are transmitted using only the some layers with a relatively high MCS. |
