ABSTRACT:
In a mobile station apparatus of this invention, when a first offset is captured by a search operation performed by a first PN code search mode, it is checked, on the basis of the SID broadcasted from the corresponding base station through a sync channel, whether a base station of a desired carrier is captured. If a base station of an undesired carrier is captured, a second PN code search mode receives a neighbor list message broadcasted from the base station of the undesired carrier through a paging channel, and causes a search receiver to perform a search operation, excluding spreading code offsets notified by the message.
