A radio communication system includes a base station and a mobile station communicating with the base station. The base station includes a selection unit and a first transmitting unit. The selection unit selects an item of identification information for identifying a data series from a plurality of data series corresponding to resources used to transmit a signal that the mobile station uses to measure reception quality. The first transmitting unit transmits the item of identification information. The mobile station includes a receiving unit, a measurement unit, and a second transmitting unit. The receiving unit receives the item of identification information that the first transmitting unit has transmitted. The measurement unit measures the reception quality using a signal of the data series identified by the item of identification information. The second transmitting unit transmits information indicating the reception quality that the measurement unit has measured to the base station.
