    • A method and apparatus for controlling a primary cell search operation including generating a profile of correlation peaks, determining if magnitudes of the correlation peaks vary, synchronizing a signal acquisition process to one of the identified correlation peak having a greatest magnitude if the magnitudes of the correlation peaks remain relatively constant and synchronizing the signal acquisition process to a peak whose magnitude is increasing if the magnitudes of the correlation peaks are changing, is described. The method and apparatus further includes identifying an index and a magnitude of a largest correlation peak of the correlation peaks, determining if other correlation peaks exist in the profile, synchronizing the signal acquisition process to the largest correlation peak originally identified if other correlation peaks do not exist, storing indices and magnitudes for all other correlation peaks located and comparing changes in correlation peak magnitudes for all previously identified peaks.
    • 一种用于控制主小区搜索操作的方法和装置,包括生成相关峰值的轮廓,确定相关峰值的幅度如何变化,如果相关幅度大小,则将信号采集过程与所识别的相关峰之一同步,具有最大幅度 峰值保持相对恒定,并且如果相关峰值的幅度正在改变,则将信号采集过程同步到其幅度正在增加的峰值。 所述方法和装置还包括识别相关峰值的最大相关峰值的指标和幅度,确定在轮廓中是否存在其它相关峰值,如果其它相关峰值不是,则将信号获取过程同步到最初识别的最大相关峰值 存在,存储所有其他相关峰的索引和幅度,并比较所有先前识别的峰的相关峰值幅度的变化。
