Claim Text:
1. A transmitting apparatus that maps a control signal for a receiving apparatus to a first resource region usable for both a control channel and a data channel or a second resource region usable for a control channel and transmits the mapped control signal, and maps transmission data to a data resource region and transmits the mapped transmission data to the receiving apparatus, the transmitting apparatus comprising: a generating section that generates an allocation control signal for the data resource region; a setting section that sets a first data resource region within the first resource region in a resource block group (RBG) composed of M resource blocks (RBs), where M is a natural number equal to or greater than two, when the number of streams used to transmit the transmission data is one and an antenna port used to transmit the transmission data is identical to the antenna port used to transmit the allocation control signal, and that sets a second data resource region larger than the first data resource region within the first resource region in the RBG when the number of streams used to transmit the transmission data is one and the antenna port used to transmit the transmission data is different from the antenna port used to transmit the allocation control signal; and a mapping section that maps the transmission data to the set first data resource region or the set second data resource region, and maps the allocation control signal to a control resource region within the first resource region.
