RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD

摘要

Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when a reception of scheduling information has failed in the retransmission method using a combination of the adaptive HARQ and the non-adaptive HARQ.  In ST301, a resource control unit (206) stores resource allocation information and scheduling timing information transmitted from a base station (100).  ST302 checks whether the scheduling information has been acquired.  ST303 applies the adaptive HARQ.  ST304 checks whether the scheduling information not acquired in ST302 has been acquired at the timing indicated by the scheduling timing information.  In ST305, a resource control unit (206) instructs stop of the packet transmission.  In ST306, the resource control unit (206) employs the non-adaptive HARQ.
