摘要：
A wireless communication apparatus includes a designation unit which generates format designation information for designating a format of transmission and reception for another wireless communication apparatus, a first transmission unit which wirelessly transmits the format designation information to the other wireless communication apparatus, an acquisition unit which acquires a packet, a propagation channel estimation unit which estimates uplink propagation channel information indicating a propagation channel from the other wireless communication apparatus to the wireless communication apparatus based on the packet, a calibration coefficient calculation unit which calculates a calibration coefficient based on downlink propagation channel information indicating a propagation channel from the wireless communication apparatus to the other wireless communication apparatus and the uplink propagation channel information, a transmission weight value calculation unit which calculates a transmission weight value based on the calibration coefficient and the uplink propagation channel information, and a second transmission unit which wirelessly transmits a predetermined signal to the other wireless communication apparatus based on the transmission weight value.
