摘要： In a wireless communication system in which a base station, a mobile station, and a correspondent station are connected via a network, the base station includes a sounding-reference-signal arrangement control unit that causes sounding reference signals 5, 6, and 7, which are used for observing a propagation path state in the frequency band and are transmitted from the mobile station to the base station, to be transmitted for each of frequency bandwidths obtained by dividing the frequency band into a plurality of frequency bands in a minimum control time of the data transmission and in a time width shorter than the minimum control time, determines an arrangement of sounding reference signals 5, 6, and 7 in the minimum control time so that at least a part of transmission in the frequency bandwidth and transmission in another frequency bandwidth are executed at different times, and holds the arrangement as arrangement information. The mobile station includes a sounding-reference-signal transmission control unit that controls transmission of the sounding reference signals 5, 6, and 7 based on the arrangement information in the sounding-reference-signal arrangement control unit.
