Claim Text:
1. A radio base station used in a mobile communication system where the radio base station receives multiple downlink signals transmitted with an identical scrambling code from multiple cells geographically apart from each other, comprising: a receiver configured to receive the downlink signals from the cells through a plurality of paths; and circuitry configured to determine the downlink signals with the identical scrambling code as a same downlink signal transmitted from an identical cell based on determining that an arrival time difference between the downlink signals with the identical scrambling code is equal to or smaller than a predetermined value, and to determine the downlink signals with the identical scrambling code as downlink signals transmitted from different cells based on determining that the arrival time difference between the downlink signals with the identical scrambling code is larger than the predetermined value.
