Abstract: A system and method for assisting an integrated GPS/wireless terminal unit in acquiring one or more GPS satellite signals from the GPS satellite constellation. The invention includes a method for narrowing the PN-code phase search. That is, by accounting for the variables in geographic location and time delay relative to GPS time, the systems and methods of the present invention generate a narrow code-phase search range that enables the terminal unit to more quickly acquire and track the necessary GPS satellites, and thereby more quickly provide accurate position information to a requesting entity.

Abstract: Techniques for transmitting signaling information for broadcast and multicast services are described. A base station transmits signaling information for each service in accordance with a schedule that includes a repetition period and a modification period. The signaling information is sent in each repetition period to allow wireless devices to quickly obtain this information. Changes to the critical signaling information are permitted at the start of each modification period, which is an integer multiple of the repetition period. Whenever the critical signaling information for a given service is changed in a given modification period, a notification indicator for the service is set in an entire preceding modification period to inform the wireless devices of the impending change. The wireless devices can detect the notification indicator being set in the preceding modification period and can retrieve the updated critical signaling information in the following modification period.

Abstract: Various embodiments are provided for determining a set of acceptable transport format combinations for transmission on a current time frame. A set of acceptable modified rate power adjustment values is determined based on a maximum power level, an accumulated power commands and an initial power control command. A set of acceptable channel gain factors is determined based on the set of acceptable modified rate power adjustments values, and the set of acceptable transport format combinations is determined based on the set of acceptable channel gain factors. A possible set of modified rate power adjustment values is associated to a set of channel gain factors for determining the set of accepted channel gain factors based on various design of a transmitter chain used for transmission of data from the mobile station.

Abstract: An apparatus and method for locating a remote station in a synchronous communications network using the time of arrival of a reference pilot signal at the remote station as a time reference. The time difference of arrival (TDOA) of GPS signals received by the remote station and other signals received from a base station, are measured relative to this reference time. From these measurements, the location of the remote station is determined. The invention treats the location issue as a TDOA problem.

Abstract: Se proporcionan tecnicas de transmision que mejoran la continuidad de servicio y reducen interrupciones en la distribucion de contenido que pueden provocarse por transiciones que ocurren cuando el Equipo de Usuario (UE) se mueve de una celda a otra, o cuando la distribucion de contenido cambia de una conexion de Punto a Punto (PTP) a una conexion de Punto a Multipunto (PTM) en la misma celda de servicio, y viceversa. Tales tecnicas de transmision permiten distribucion fluida de contenido a traves de bordes de celdas y/o entre diferentes esquemas de transmision tal como Punto a Multipunto (PTM) y Punto a Punto (PTP). Los mecanismos para ajustar diferentes corrientes y para recuperar contenido de cada bloque de datos durante tales transiciones tambien se proporcionan de manera que los datos no se pierden durante una transicion. Ademas, tambien se proporcionan mecanismos para realinear datos durante la descodificacion en una terminal de recepcion.

Abstract: A method and apparatus provides for efficient use of communication resources in a CDMA communication system (100) by selecting, at a time prior to a first time period (401), a first mobile station to receive transmission during the first time period (401) on a downlink shared channel, and selecting, at a time prior to the first time period (401), a second mobile station to receive transmission during a second time period (402) on the downlink shared channel. Transmission power level of a downlink shared control channel is determined for transmission to the second mobile station during an overlapping time period (403) with the first time period (401), and the transmission power level of the downlink shared channel for transmission during the first time period (401) is determined based on at least the determined transmission power level of the downlink shared control channel during the overlapping time period (403).

Abstract: Se expone un metodo y un sistema que permita multiplexar una pluralidad de corrientes de datos sobre una corriente de datos con base en las prioridades de la corriente de datos y las combinaciones de trama de transporte (TFC) disponibles. Una estacion movil 12 tiene aplicaciones que producen corrientes de datos por separado. Aplicaciones de ejemplo incluyen voz 32, senalizacion 34, E-mail 36 y aplicaciones web 38. Las corrientes de datos se combinan mediante un modulo multiplexor 48 en una corriente de datos denominada la corriente de transporte 50. La corriente de transporte 50 se envia sobre el enlace inverso a los transceptores de la estacion base (BTS) 14. El modulo multiplexor 48 multiplexa las corrientes de datos sobre la corriente de transporte de acuerdo con sus prioridades y las TFC disponibles.
