    Abstract: A mobile terminal communicating with a plurality of cells, including a serving cell, has a control unit. The control unit performs at least one control of (a) a first control for causing a path search unit to detect a path for the serving cell more preferentially than paths for cells other than the serving cell, (b) a second control for causing a finger assignment unit to assign a path detected for the serving cell preferentially over paths detected for cells other than the serving cell to a plurality of fingers, and (c) a third control for causing a reference frequency adjustment unit to adjust reference frequency so that the reference frequency is approximated to reference frequency of a base station controlling the serving cell.

    Abstract: Cell timing is detected by first trying to detect a target handover cell through detecting a primary synchronization channel (P-SCH) followed by a common pilot channel (CPICH). If that fails, N number of retrials is performed using a full-window search on the CPICH. The full-window CPICH search is performed blindly, without any slot timing information from the P-SCH. Performance is improved while maintaining the benefits of faster acquisition methods in good channel conditions. The full-window search is more time consuming, but takes advantage of the stronger CPICH transmission. In good channel conditions, a mobile device can proceed quickly with the normal method of timing acquisition. With failure, the mobile device can switch to the longer search which has a higher probability of successfully completing the hard handover procedure. The overall effect is a higher success rate of hard handovers without a uniform increase of time spent in cell timing acquisition.

    Abstract translation: 通过首先通过检测跟随公共导频信道（CPICH）的主同步信道（P-SCH）来尝试检测目标切换小区来检测小区定时。 如果失败，则使用CPICH上的全窗口搜索来执行N次重试。 完全窗口CPICH搜索盲目执行，没有来自P-SCH的任何时隙定时信息。 性能得到改善，同时在良好的通道条件下保持更快的采集方法的好处。 全窗口搜索更耗时，但利用更强的CPICH传输。 在良好的信道条件下，移动设备可以通过正常的定时采集方法快速进行。 随着故障，移动设备可以切换到成功完成硬切换过程的较高概率的较长搜索。 总体效果是更高的硬切换成功率，而没有在单元定时采集中花费的时间的均匀增加。

    Abstract: In general, the invention facilitates searching for energy peaks in spread spectrum wireless communication systems with greater precision. More particularly, various embodiments of the invention may involve reporting not only an energy peak and its associated offset, but also the energy levels corresponding to one or more offsets occurring before and after the offset at which the energy peak occurs. Interpolation or extrapolation techniques may be used to predict the actual location of an energy peak based on the apparent location of the peak and the energy levels observed at surrounding offsets.
