Radio Communication System, Radio Communication Device, and Radio Communication Method

摘要

One of objects of the present invention is to enhance stability of radio communication by switching between ARQ and HARQ according to whether or not signal quality of received data is deteriorated, such that efficiently perform error correction, when an error is detected in the received data. In a radio communication device (e.g., a PHS terminal 110) in a radio communication system 100 of the present invention, a retransmission request selection section 342 selects an ARQ processing section 370 when a signal quality determination section 340 determines that a Signal to Interference and Noise Ratio, which serves as measured signal quality, is deteriorated and selects an HARQ processing section 350 when the signal quality determination section 340 has determined that the measured Signal to Interference and Noise Ratio is not deteriorated.
