Abstract: PROBLEM TO BE SOLVED: To provide techniques for limiting cell reselection in response to a variable channel.
SOLUTION: In one aspect, a measurement of received pilot power from a base station is used as an indication of channel quality. In another aspect, hysteresis is applied to limit cell reselection, wherein the hysteresis is greater in relatively higher quality channel environments and lower in relatively lower channel quality environments. Various other aspects are also presented. These aspects have the benefit of reducing cell reselection, thus increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.

Abstract: PROBLEM TO BE SOLVED: To achieve position determination in a wireless communication system with detection and compensation for repeaters. SOLUTION: In order to detect whether or not a remote terminal is under the coverage of a repeater in a wireless communication network, techniques may be based on (1) a list of base stations expected to be received under the coverage of the repeater and (2) a characterized environment of the repeater or (3) a propagation delay for a transmission received at the remote terminal. Additional ambiguity resulting from being under the coverage of the repeater may be also accounted for or compensated by (1) discarding time measurements from repeated base stations, (2) adjusting processing for position estimates, and (3) computing a series of position estimates based on multiple transmissions received from the same originating base station and selecting the best estimate, or (4) computing a series of position estimates based on multiple transmissions from multiple originating base stations and selecting the best estimate.

Abstract: 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.

Abstract: A system and method are disclosed by which the effects of time of arrival (TOA) errors may be reduced. In a mobile unit, a correlation pulse is generated 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. This leads to a distortion in the generated correlation pulse and errors in accurate (TOA) measurements. The present invention 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 the 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 global positioning system (GPS) satellites.

Abstract: A system and method are disclosed by which the effects of time of arrival errors may be reduced. In a mobile unit, such as a CDMA device, a correlation pulse is generated when a transmitted code matches a stored reference code. In the absence of multipath effects, correlation pulses are generated in response to the detection of multiple transmissions of the reference code from multiple transmitters. However, multipath effects distort the generated correlation pulses leading to errors in the time of arrival measurements. The present invention calculates the width of the correlation pulses and determines a delay correction factor based on the pulse width. The delay correction factor is added to the measured delay time to provide a more accurate delay time, thus permitting more accurate location measurements based on time of arrival. In alternative embodiments, other signal factors may also be used to apply delay correction factors. The actual location determination may be performed by the mobile unit, or any other positioning determining entity (PDE). The system is also capable of applying correction factors to time of arrival signals received from global positioning system (GPS) satellites.

Abstract: An apparatus, such as a subscriber unit or a base station within a spread spectrum communication system, may add one or more additional "virtual" paths to a list of candidate paths when assigning demodulation elements. These "virtual" paths are added as candidate paths even though a corresponding peak was not necessarily detected within a received spread spectrum system. The list of paths may include a first path having a time offset approximately equal to a time offset for one of the demodulation elements, and the virtual path having a short time separation from the first path. The time separation between the paths may be, for example, less than 2 chips.

Abstract: A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit enters an "active state" during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The order that the searches are performed is based on the measured signal strength and the age of the measurement. The search engine performs searches using the selected sets of search parameters. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases. While in the inactive state, the controller evaluates the results of the searches performed during the previous active state. During the next active state, the next sequence of searching is performed based on measured signal strength and the measurement age corresponding to the measurements made during the previous active state.
