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： 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： An access terminal (102) reacquires a system frame number (SFN) when a difference between a continuous counter elapsed time (220) and a calculated elapsed time (222) exceeds a threshold. The continuous counter elapsed time (220) is generated by a continuous counter (122) remaining active during a sleep state of the access terminal (102) and the calculated elapsed time (222) is based on a SFN derived from a counter value generated by a discontinuous counter (124) that is deactivated during the sleep state. In one aspect, the continuous counter (122) may be clocked by a continuous clock (118) during a sleep mode and the discontinuous counter (124) may be clocked by a faster clock (120) that is deactivated during the sleep mode. During reactivation after the sleep mode, the discontinuous counter (120) is set, at the counter set time, to a reset counter value (126) corresponding to an SFN indicated by the continuous counter (122).

摘要： Techniques for reducing search time using known scrambling code offsets are disclosed. In one embodiment, a plurality of search results is generated by correlating a received signal with a synchronization sequence. The plurality of search results is reduced by removing any results within a stored threshold. Further, the plurality of search result is reduced by removing those results already detected in a previous analysis.

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.

摘要： A method and apparatus for reducing frequency space from code space search is disclosed in a wireless network. The method and apparatus reduces the frequency space without compromising the probability of detection, so that user equipment can expedite system acquisition and reduce power consumption. To reduce the frequency space, the described aspects note that the power spectral density of the WCDMA signal is essentially flat within the channel bandwidth. By capturing in-phase quadrature samples and doing frequency domain analysis of the signal in bandwidth around the center frequency, to the described aspects can eliminate some channels from the WCDMA code space search during frequency scan.

摘要： The disclosure is directed to techniques for performing service signal searches with reduced power consumption when a wireless communication device is operating out of service. The techniques include placing the wireless communication device in a "deep sleep" mode when the wireless communication device is not in service. When operating in the deep sleep mode, the wireless communication device reduces power consumption by not looking for paging signals or searching for service signals. The wireless communication device then may periodically enter a wake-up period during which power consumption is increased to perform signal searches in one or more frequency bands. The wireless communication device returns to the deep sleep mode when the signal searches are unsuccessful.

摘要： For cell measurement, a wireless device categorizes cells whose identities are known to the device into multiple sets. The wireless device may obtain these cells from the system via signaling and/or detect these cells via searches. Different sets of cells may be associated with different levels of importance (e.g., for handoff), require different amounts of processing for measurements, and so on. Each set is associated with a particular measurement rate. Cells deemed to be more important (e.g., for handoff) are measured more frequently. Cells deemed to be less important and/or require more processing for measurements (e.g., cells with unknown timing) are measured less frequently. The wireless device performs searches and makes measurements for the cells in each set at the measurement rate selected for that set.

摘要： Techniques for efficiently performing system search to obtain service from a wireless system as quickly as possible are described. A terminal initially looks for service from a first (e.g., W-CDMA) system. The terminal identifies network(s) in the first system from which service was received in the past and performs acquisition on each network to look for service. If service is not found for the first system, then the terminal performs a search for a second (e.g., GSM) system. If service is found on the second system, then the terminal obtains service from the second system and avoids a frequency scan for the first system. Otherwise, the terminal performs a frequency scan for the first system using the search results for the second system. The terminal may obtain a list of RF channels detected for the second system and may omit these RF channels and possibly some other RF channels around these RF channels from the frequency scan.
