1. A radio communication apparatus comprising:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to:
calculate a degree of distortion of a frequency response of a channel between the radio communication apparatus and a radio terminal, the distortion of the frequency response of the channel being due to multipath propagation in the channel; and
assign a reference signal to the radio terminal based on the degree of distortion,
wherein the at least one processor is further configured to execute the instructions to assign the reference signal to the radio terminal by setting at least one of a transmission interval of the reference signal and a transmission bandwidth thereof based on the degree of distortion.
