<p>A radio signal receiving method in which a physical channel coming from a base station in a radio communication system at an unscheduled timing is demodulated from a high frequency signal to a base band signal, the base band signal is demodulated and output as a decoded base band signal, and a desired channel included in the decoded base band signal is decoded by a communication control unit (13) for performing the communication control. The method comprises a determination step of determining whether the signal of the desired channel is present in the physical channel of the decoded base band signal and outputting the result of determination, a wake-up step of turning on a power source of the communication control unit (13) if the result of determination indicates the presence of the desired channel, and a sleep step of turning off the power source of the communication control unit if it is ascertained that the communication control unit does not need to operate when the power source of the communication control unit (13) is on. Thus, it is possible to reduce The power consumption of a mobile station (1).</p> |
