Abstract
A base station includes a processor. The processor is configured to transmit, to each of terminal devices, a data signal and a reference signal used for demodulating the data signal while the data signal and the reference signal are spatially multiplexed, by forming a plurality of beams while using a plurality of antenna elements. The processor is configured to calculate an index value related to correlation among the terminal devices, on a basis of propagation path information between any of the terminal devices subject to the spatial multiplexing. The processor is configured to assign the reference signals to the terminal devices subject to the spatial multiplexing in accordance with the index values among the terminal devices.
