A radio communication apparatus for performing radio communication with a terminal apparatus, including: a calculation unit which calculates first and second propagation distances indicating path lengths of first and second paths respectively; a decision unit which determines whether the first and second received waves are reflected waves or direct waves, respectively, based on the first and second propagation distances, and outputs a first or second terminal-reflection point distance on determining the first or second received wave as the reflected wave, or outputs the first or second propagation distance on determining the first or second received wave as the direct wave; and a position measurement unit which measures the position of the terminal apparatus based on the first or second terminal-reflection point distance, or the first or second propagation distance.
