Abstract: An apparatus and method for locating a remote station operating in analog mode, and that may not have a sense of network time, using an inverted GPS approach. The invention also enables remote stations operating in analog mode that do not know true GPS time to determine their own location. A time stamp, reflecting the approximate time a satellite range measurement is made, is assigned to the measurement at either the remote station or elsewhere in the network. The difference between true GPS network time and the measurement time is treated as a variable "error" in measurement, the length of which is unknown. This variable error is determined and used in determining the physical location of the remote station.

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: Method and apparatus for reducing interference in a wireless communication system when the source of interference is a deterministic component of the system. In one embodiment, the receiver weights the transmitters according to when the source of interference is transmitted. Further, the transmitter may employ power boosting to overcome the source of interference. In one embodiment, a W-CDMA system transmits a sync channel concurrently with physical channels, wherein the sync channel is not orthogonal to the physical channels. The receiver may cancel the sync channel when receiving control or data information. Similarly, the receiver may weight the transmissions from multiple transmitters.

Abstract: Un procedimiento para determinar combinaciones de formato de transporte, en adelante TFC, para su uso en un intervalo de tiempo de un sistema de comunicaciones inalámbrico, que comprende: identificar diferentes combinaciones para cada TFC de un conjunto de TFC sobre la base de una pluralidad de modos de transmisión; determinar una potencia de transmisión requerida para cada una de dichas combinaciones; determinar un estado de cada una de dichas combinaciones en base a la potencia de transmisión requerida determinada y una potencia de transmisión disponible máxima; y seleccionar una o más de dichas combinaciones para su posible uso en un intervalo de tiempo próximo en base a un estado determinado.

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: Techniques for determining valid (i.e., supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that 'TFC qualification' may be accurately performed. In a first scheme, Tx_power-requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative 'bins' that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.

Abstract: A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities and available transport frame combinations (TFCs) is disclosed. A mobile station 12 has applications that produce separate data streams. Example applications include voice 32, signaling 34, E-mail 36 and web applications 38. The data streams are combined by a multiplexer module 48 into one data stream called the transport stream 50. The transport stream 50 is sent over the reverse link to base station transceivers (BTS) 14. The multiplexer module 48 multiplexes the data streams onto the transport stream according to their priorities and the available TFCs.

Abstract: Se proporcionan tecnicas de transmision que mejoran la continuidad de servicio y reducen interrupciones en la entrega o distribucion de contenido que pueden ser causadas por transiciones que ocurren cuando el Equipo de Usuario (UE) se mueve de una celula a otra, o cuando la entrega de contenido cambia de una conexion Punto a Punto (PTP) a una conexion de un Punto a Puntos Multiples (PMT) en la misma celula de servicio, y viceversa. Esas tecnicas de transmision permiten una entrega o distribucion imperceptible de contenido a traves del limite de celulas y/o entre diferentes esquemas de transmision como el de un Punto a Puntos Multiples (PMT) y Punto a Punto (PFT). Tambien se proporcionan los mecanismos para ajustar los diferentes flujos y para recuperar el contenido de cada boque de datos durante esas transiciones, de modo no se pierdan datos durante una transicion. Ademas, tambien se proporcionan mecanismos para realinear datos durante la descodificacion en una terminal receptora.

Abstract: Techniques for delivering data recovered by an HARQ entity in proper order to higher layers in a CDMA system. In a method, packets are received from the HARQ entity by the re-ordering entity and missing packets among the received packets are detected. Packets may be transmitted in a sequential order based on transmission sequence numbers (TSNs) assigned to the packets, and missing packets may be detected based on the TSNs of the received packets. Delivery of received packets later than the missing packets are stalled because higher layers expect data in-order. A determination is thereafter made whether each missing packet is (1) subsequently received from the HARQ entity or (2) lost, by successively eliminating HARQ channels that may be used to send the missing packet. Received packets previously stalled by each missing packet are delivered after the missing packet is determined to be lost or received.
