A wireless communication apparatus configured to select an allocation system for transmission symbols on the basis of transmission line situations between the wireless communication apparatus and terminals includes a channel estimator to estimate transmission line coefficients between communication target terminals and sub-arrays, a resource scheduler to generate, on the basis of the transmission line coefficients, mapping information and transmission weight information by spatial multiplexing and frequency multiplexing and select and output the mapping information and the transmission weight information by one of the multiplexing systems, a symbol mapper to map transmission symbols on a frequency axis on the basis of the mapping information from the resource scheduler, and a pre-coder to perform, on the basis of the transmission weight information from the resource scheduler, a weighting operation concerning a signal mapped by the symbol mapper.
