摘要： 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.
摘要翻译：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。

摘要： A terminal communicates with a first wireless network and obtains a list of cells in a second wireless network to measure. The terminal operates in a compressed mode and receives multiple transmission gap pattern sequences for different measurement purposes, e.g., RSSI measurements, BSIC identification, and BSIC re-confirmation. The terminal utilizes each transmission gap for its designated purpose or an alternate purpose. For each transmission gap, the designated purpose for the transmission gap is ascertained, and whether the transmission gap is usable for an alternate purpose is also determined based on at least one criterion. The transmission gap is used for the alternate purpose if the at least one criterion is satisfied and is used for the designated purpose otherwise. For example, a transmission gap designated for RSSI measurement may be used for BSIC identification, a transmission gap designed for BSIC identification or BSIC re-confirmation may be used for RSSI measurement, and so on.

摘要： A rake receiver finger assignor is configured to assign a rake receiver finger to a time offset between identified signal path time offsets in accordance with a concentration of identified signal paths from a transmitter to a rake receiver. In accordance with the exemplary embodiment, a number of identified signal paths having time offsets within a time window are observed to determine the concentration of signal paths identified by a path searcher. If the number of identified signal paths indicates a concentrated distribution of signal paths such as during a fat path condition, at least one rake finger is assigned between at a time offset between two identified signal paths.

The processing system is configured to assign a plurality of demodulation elements from a plurality of receive antennas to a multipath group, assign the multipath group to a multipath signal, and independently adjust a time delay value of each demodulation element in the multipath group to correspond to a local time delay of the multipath signal at the corresponding receive antenna.
