摘要： Methods and apparatus for out of service processing with varied behaviors. In an aspect, a method is provided for service acquisition. The method includes determining one or more conditions, wherein each condition is associated with at least one weight, detecting whether an out-of-service event has occurred, and if an out-of-service event is detected: identifying selected conditions and associated weights, and processing the associated weights to determine service acquisition “on” and “off” times. In an aspect, an apparatus includes condition logic configured to determine one or more conditions, wherein each condition is associated with at least one weight, and processing logic configured to detect whether an out-of-service event has occurred, and if an out-of-service event is detected, to identify selected conditions and associated weights, and process the associated weights to determine service acquisition “on” and “off” times.

摘要： A quick paging channel (QPCH) is used to receive paging indicators that indicate that a wireless communication device (WCD) has a message on a paging channel relating to, for example, an incoming call to the WCD. When the condition of the quick paging channel is too low to receive paging indicators reliably, the quick paging channel is disabled to avoid false alarms, and the slotted paging channel is used to receive paging messages without monitoring the QPCH. When the QPCH signal is strong, the probability of false alarms is lower, and the quick paging channel is enabled. By using the quick paging channel to receive paging indicators only when the QPCH signal is strong, the wireless communication device can remain in a sleep state for greater periods of time as compared with the use of a slotted paging channel. As a result, standby time may be significantly improved.

摘要： A method and communication system for assigning the plurality of fingers to demodulation paths in a path list which insures that at least one finger will be assigned to a demodulation path supporting a supplemental channel, if one exists. The method involves determining whether any of the fingers is demodulating a supplemental channel (112). When no fingers are demodulating supplemental channels, the it is determined whether the sector containing the path under consideration supports supplemental channels (114). If the sector containing the path under consideration supports supplemental channels, then the method determines the strength of the signal path relative to the weakest finger (116). If the path is a certain amount greater in strength then the weakest finger, then the method involves reassigning that finger to the path with the supplemental channel (108) and if the path with the supplemental channel is a certain amount of strength weaker than the weakest finger plus a certain value, then the method involves determining whether the weakest finger is the only one supporting the supplemental channel (118). If the weakest finger is the only one supporting supplemental channels, and the sector supports supplemental channels (120), then that finger is assigned to the demodulation path with the supplemental channel (108), thus insuring that the information on a supplemental channel is always demodulated by a finger during a soft-handoff in a high data rate call if one or more fingers are already demodulating supplemental channels, then the finger assignment algorithm will proceed in the conventional way.

摘要： MAINTAINING AND SEARCHING SETS OF CELLS IN A WIRELESS COMMUNICATION SYSTEM 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： A method for assigning tracking elements includes sorting a list of potential assignments according to a diversity criterion. In one example, a list of received signal instances is sorted first according to a measure of energy and then sorted again according to the diversity criterion. In a further embodiment, a demodulation element may be labeled available for assignment yet continue to output demodulated symbols in a locked state. Applications to a mobile station of a CDMA system for cellular telephony are discussed.

摘要： A system and method to reduce-the effects of TOA errors. A mobile unit, generates a correlation pulse when a signal transmitted from a base station is detected. The transmitted signal may be reflected or defracted such that multipath signals arrive at the mobile unit, leading to distortion in the generated correlation pulse and errors in accurate TOA measurements. The system models the response function and calculates the width of the pulse using the modeling function with a dynamically adjustable factor to indicate at what point down from the peak the pulse width will be calculated. Based on calculation of pulse width, a type of multipath signal may be determined and an appropriate correction factor applied to the measured TOA to provide a more accurate TOA determination. The system may apply correction factors to TOA signals from base stations in a mobile telephone unit or from signals received from GPS satellites.
