Title:
基地局装置、移動局装置、通信システムおよび通信方法
Document Type and Number:
Japanese Patent JP4904398
Kind Code:
B2
Abstract:
By changing a scrambling code to be multiplied with a secondary synchronization channel for a different sub-frame number, the number of codes required to be retained in a mobile station apparatus is reduced and also a circuit scale and a computation amount thereof are reduced, while an effect of causing interference from a neighboring cell to be random is being maintained. There are provided a primary synchronization channel generation unit (50) generating a primary synchronization channel according to base station apparatus information, a secondary synchronization channel generation unit (51) generating a secondary synchronization channel composed of a combination of a first signal and a second signal according to the base station apparatus information, a first scrambling code generation unit (52) generating a first scrambling code to be multiplied with the secondary synchronization channel according to the primary synchronization channel, and a second scrambling code generation unit (53) generating a second scrambling code to be multiplied with the second signal according to the first signal.
