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： 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.

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： 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).
摘要翻译：当连续计数器经过时间（220）和计算出的经过时间（222）之间的差超过阈值时，接入终端（102）重新获取系统帧号（SFN）。连续计数器经过时间（220）由在接入终端（102）的休眠状态期间保持活动的连续计数器（122）生成，并且所计算的经过时间（222）基于从由在休眠状态期间停用的不连续计数器（124）。在一个方面，连续计数器（122）可以在休眠模式期间由连续时钟（118）计时，并且不连续计数器（124）可以由在睡眠模式期间被去激活的更快的时钟（120）来计时。在休眠模式之后的再激活期间，不连续计数器（120）在计数器设定时间被设置为对应于由连续计数器（122）指示的SFN的复位计数器值（126）。

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 parameter estimator for estimating one or more parameter(s) from a correlation function derived from a signal using a dynamically variable integration time is described. The parameter estimator may be employed in a subscriber station to estimate the time of arrival of one or more base station or sector pilot signals in a wireless communication system. This information may be utilized in an overall advanced forward link trilateration (AFLT) process for estimating the location of the subscriber station.
