The present invention provides a mobile station which can reduce the power consumption of an operation of intermittent reception in accordance with an elapsed time after transmission or reception. When a mobile station intermittently receives signals from another mobile station after transmission or reception, the interval of intermittent reception is not made constant, but the interval of the intermittent reception is made short immediately after transmission or reception, and as the time passes thereafter, the interval of the intermittent reception is made longer than that immediately after transmission or reception. Further, when the interval of the intermittent reception is made long and becomes a predetermined interval, the interval of the intermittent reception can be maintained at the predetermined interval and made constant thereafter. Accordingly, the interval of a reception timing can be set in accordance with a state after completion of reception or completion of transmission.
