PROBLEM TO BE SOLVED: To improve a standby time by reducing consumption current of radio mobile equipment of a CDMA system. SOLUTION: In a first step, the radio mobile equipment of a CDMA system spreads inversely a P-SCH signal by using PSC, and detects the slot timing (step S301). After transition to a second step, CPICH is spreaded reversely to 15 frame timing candidates by using peripheral station scramble codes, and frame timings are detected (step S303). In all the frame timings based on the slot timing detected in the first step, the mobile radio equipment of a CDMA system performs reverse spreading by using the peripheral station scramble codes given by the information, thereby detecting the frame timing. |
