ABSTRACT:
Provided is a radio communication method or the like for making compatible an improvement in error rate characteristics and a reduction in delay. The radio communication method is used in a mobile communication system (1) including a mobile station (10), a relay station (20) and a base station (30). A transmitted signal containing a signal addressed to the base station (30) is transmitted at first from the mobile station (10) to the relay station (20). A non-reproduced relay signal obtained in the relay station (20) from the transmitted signal is transmitted from the relay station (20) to the base station (30). On the basis of the reception result of the non-reproduced relay signal at the base station (30), a re-transmission request of the transmitted signal is transmitted from the base station (30). A reproduced relay signal, as obtained from the transmitted signal in the relay station (20), is transmitted from the relay station (20) to the base station (30) in accordance with the re-transmission request transmitted from the base station (30).
