Abstract
A base station () according to the present invention includes: a control unit () that allocates one or more layers per terminal for transmission to one or more terminals, and configures positions in a frequency domain and a time domain of reference signals of each of the layers on the basis of at least one of information indicating a position of each of the terminals and information indicating condition of each of channel between the transmission device and the one or more terminals; a processing unit (-to-N) that arranges the reference signals of each of the layers in the frequency domain and the time domain on the basis of the positions in the frequency domain and the time domain configured by the control unit (); and a precoding unit () and a transmitting unit () that perform space-division multiplexing on signals of one or more layers arranged by the processing unit (-to-N), and transmit the multiplexed signals.
