    • PROBLEM TO BE SOLVED: To provide a communication system, data transmission method, and base station system for enabling reliable synchronization in the communication system. SOLUTION: The communication system is characterized in that a primary common control physical channel (P-CCPCH) and a synchronization channel (SCH) are transmitted in a time division multiplexing manner, transmission power of a dedicated channel (DCH) is reduced during transmission on the synchronization channel (SCH), the transmission power of the dedicated channel (DCH) is reduced by a difference between transmission power of the synchronization channel (SCH) and transmission power of the primary common control physical channel (P-CCPCH) when starting the synchronizing channel (SCH). The transmission power of the dedicated channel (DCH) is increased by the difference between the transmission power of the synchronization channel (SCH) and the transmission power of the primary common control physical channel (P-CCPCH) when ending the synchronization channel (SCH).

    • 要解决的问题:提供一种用于在通信系统中实现可靠同步的通信系统,数据传输方法和基站系统。 解决方案:通信系统的特征在于以时分复用方式发送主通用控制物理信道(P-CCPCH)和同步信道(SCH),减少专用信道(DCH)的发送功率 在同步信道(SCH)的发送期间,专用信道(DCH)的发送功率通过同步信道(SCH)的发送功率与主通用控制物理信道(P-CCPCH)的发送功率之间的差减小, 当启动同步信道(SCH)时。 当结束同步信道(SCH)时,专用信道(DCH)的发送功率由同步信道(SCH)的发送功率与主要公共控制物理信道(P-CCPCH)的发送功率之差增加, 。 版权所有(C)2009,JPO&INPIT
