Patent ID: 8000651

Claim:
A wireless transmission apparatus comprising: a transmitting section that transmits a transmission signal for a communicating party apparatus, to a plurality of relay station apparatuses, each of the plurality of relay station apparatuses generating a relay signal from the transmission signal and transmitting the generated relay signal to the communicating party apparatus; a determining section that outputs a first command to generate a first relay signal from the transmission signal and a second command to generate a second relay signal from the transmission signal, the second relay signal being different from the first relay signal and combinable with the first relay signal at the communicating party apparatus that receives the first relay signal and the second relay signal; and a reporting section that reports the first command to a first relay station apparatus from among the plurality of relay station apparatuses, and reports the second command to a second relay station apparatus, different from the first relay station apparatus, from among the plurality of relay station apparatuses, wherein: the first command comprises a command to add first parity bits to the transmission signal in the first relay station apparatus, and the second command comprises a command to add second parity bits, different from the first parity bits, to the transmission signal in the second relay station apparatus.
