    Abstract: 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.

    Abstract: 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).

    Abstract: 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.

    Abstract: 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.

    Abstract: Procedimiento para realizar el seguimiento temporal de una pluralidad de demoduladores, adecuado para asignar a diversos demoduladores trayectorias múltiples poco espaciadas, presentando cada demodulador un movimiento limitado entre un límite de adelanto y un límite de atraso, que comprende las etapas siguientes: adelantar el límite de atraso de un primer demodulador adyacente a un segundo demodulador y situado por delante de éste, y el límite de adelanto de un tercer demodulador adyacente al segundo demodulador y situado por detrás de éste, cuando se envía un mandato de adelanto al segundo demodulador y atrasar el límite de atraso del primer demodulador y el límite de adelanto del tercer demodulador cuando se envía un mandato de atraso al segundo demodulador, siendo determinados los límites de adelanto y atraso de cada demodulador de acuerdo con los límites de adelanto o atraso de los demoduladores adyacentes.

    Abstract: The reliability of transmit power control (TPC) commands received from a transmitter is determined based on a TPC target value. The TPC target value is derived based on a TPC threshold and possibly a weight, depending on the receiver implementation. A received TPC command is considered reliable if its absolute value exceeds the TPC target value. Received TPC commands deemed as unreliable are discarded and not used for power control. Multiple TPC target values, used for detecting UP and DOWN commands, may be derived with multiple scaling factors. For a receiver in soft handover and receiving TPC commands from multiple transmitters, a different TPC target value may be derived for each transmitter. The received TPC commands for each transmitter are compared against that transmitter's TPC target value. Received TPC commands deemed as unreliable are discarded and not combined.
