BASE STATION APPARATUS, MOBILE STATION APPARATUS, COMMUNICATION SYSTEM, AND CELL SEARCH METHOD

摘要

There are provided a base station apparatus, a mobile station apparatus, and a cell search method capable of reducing the circuit scale of the mobile station apparatus and a calculation amount by optimizing information distribution to a primary synchronization channel (P-SCH) and a secondary synchronization channel (S-SCH). The base station apparatus transmits the P-SCH and the S-SCH as synchronization channels. The base station apparatus is equipped with an SCH signal generation unit that multiplies the S-SCH by a sequence according to a cell type of the base station apparatus.
