Abstract:
1. A mobile station apparatus of a radio communication system that performs transmission on a per-subframe basis, a subframe including a first slot and a second slot which are contiguous to each other in time, the mobile station apparatus uses a communication format capable of performing frequency hopping for allocating the first and second slots to different frequency bands on a per-slot basis or a per-subframe basis and retransmits a first subframe in a subsequent second subframe when an error is detected in a signal transmitted in the first subframe, the mobile station apparatus comprising: a control channel signal receiving section that receives a control channel signal reported from a base station apparatus; a transmission data generation section configured to generate transmission data, the transmission data being data of an initial transmission and data of a retransmission; a frequency band mapping section that maps a frequency band for the transmission data according to frequency hopping information included in the control channel signal; and a transmission section that transmits the mapped transmission data to the base station apparatus, wherein the frequency band mapping section is configured to
