摘要： A wireless communication apparatus enabling improved system throughput while limiting the amount of signaling for feedback information. In this apparatus, a setting unit (101) sets transmission power differently for each of a plurality of sub-packets obtained by dividing transmission data (transmission packet). Here, the setting unit (101) sets transmission power differently for each of the plurality of sub-packets so that the total transmission power for the plurality of sub-packets becomes the same as the transmission power that is allocated in advance to the transmission packet that constitutes the plurality of sub-packets. A dividing unit (102) divides the transmission data (transmission packet) into a plurality of sub-packets. Then, a transmitting wireless communication apparatus (100) transmits the plurality of sub-packets in order of sub-packets of higher transmission power (lower error rate).
