One object of the present invention is to improve stability of wireless communication by effectively requesting retransmission of data to a wireless communication device, which is a data transmission source, by switching ARQ and HARQ if an error has been detected in received data. In the wireless communication system of the present invention, other wireless communication device (for example, base station 120) includes a transmission data maintaining unit 230, a data transmission unit 234, a retransmission request receiving unit 236, an HARQ data retransmission unit 238, and an ARQ data retransmission unit 240. A wireless communication device (for example, PHS terminal 110) includes a data receiving unit 330, a data demodulation unit 332, an error detection unit 336, a retransmission request selection unit 338, an HARQ processing unit 340 capable of making an HARQ retransmission request, and an ARQ processing unit 360 capable of making an ARQ retransmission request.
