摘要： Un procedimiento de transmisión de una trama de datos del enlace ascendente en un sistema de comunicación inalámbrico, transportando las tramas de datos del enlace ascendente una pluralidad de paquetes de datos entre una pluralidad de Equipamientos en Instalaciones del Cliente (110), denominados también CPE (110) y una estación base (104), estableciendo cada uno de la pluralidad de CPE (110) una o más conexiones de usuario final con la estación base (104) y en la que la estación base (104) transmite asignaciones de ancho de banda a los CPE (110) en la forma de un mapa del enlace ascendente, en el que un CPE específico (110): i) almacena los datos del enlace ascendente recibidos desde las conexiones de usuario final servidas por ese CPE específico en una memoria intermedia de datos del enlace ascendente (456), ii) prioriza los datos del enlace ascendente almacenados en la memoria intermedia de datos del enlace ascendente (456) de acuerdo con un parámetro de prioridad asignado a cada una de las conexiones de usuario final. iii) identifica en el mapa del enlace ascendente recibido desde la estación base una ranura de datos planificada (326, 326', 326'') asignada a ese CPE específico dentro de una trama del enlace ascendente, iv) construye una ráfaga de datos a partir de los datos almacenados en la memoria intermedia de datos del enlace ascendente (456) para su transmisión en la ranura de datos planificada (326, 326', 326'') de la trama del enlace ascendente mediante la extracción de los datos desde la memoria intermedia de datos del enlace ascendente (456) en un orden determinado por la priorización, v) transmite la ráfaga de datos a la estación base (104) en la ranura de datos planificada (326, 326', 326'') en una trama del enlace ascendente compartida con datos del enlace ascendente desde uno o más de los otros CPE (110).

摘要： A method connects one of several customer premises equipment (CPE) via an ATM network to one of several service providers (SP). Each CPE is connected to the ATM network via a corresponding network termination point (NT). There is an access server function (ASF), having a permanent virtual connection (PVC) to each NT and a connection to each SP. A tunneling protocol is established on the permanent virtual connection between each NT and the ASF. The tunneling protocol is able to support an integrated signaling protocol. The CPE or its user select selects an appropriate SP by using the integrated signaling protocol. Routing from the CPE to the selected SP is performed by the ASF. The ASF connects the CPE to the selected SP using the integrated signaling protocol.

摘要： A multi-tiered CSI vector quantizer (VQ) is provided for time-correlated channels. The VQ operates by quantizing channel state information by reference to both the current channel state information and a prior channel state quantization. A system is also provided that uses multi-tiered CSI quantizers. Enhanced signaling between the transmitter and receivers is provided in order to facilitate the use of multi-tiered CSI quantizers.

摘要： In a telecommunications system, in which a connection comprises a part with an interworking function at both ends, a channel is allocated to the connection between the interworking functions. The required channel capabilities may vary during the connection, whereby the channel capabilites should be changed. When the first interworking function detects that a channel capability must be changed, a first message, which indicates the desired capability change, is transmitted (2-1) to the second interworking function; and the channel capability is changed (2-3, 2-5) into the desired one at both ends of the part.

摘要： A method and system for fast channel changes of media that is provided by carriers over an xDSL connection to a hom. Each customer's subscriber information is stored at the DSLAM that supports the xDSL connection to the home. Also, each DSLAM supports multicast protocols so that only one instance of a channel is provided on the core network regardless of how many customers have requested access to the channel.

摘要： Methods and apparatus for reducing transmit emissions are described herein. The transmit out of band emissions in an adjacent band can be reduced while complying with existing wireless communication standards through utilization of one or more of reduced transmit bandwidth, transmit operating band offset, and channel index remapping. The transceiver can support a receive operating band that is substantially adjacent to a band edge. The transmit operating band can be offset from an adjacent frequency band, and can use a narrower operating band than is supported by the receiver. The transmit baseband signal can have a reduced bandwidth to reduce the amount of noise. The frequency offset can introduce a larger transition band between the transmit operating band edges and the adjacent frequency band of interest. The transceiver can remap channel assignments to compensate for the frequency offset such that the frequency offset introduced in the transmitter is transparent to channel allocation.

摘要： Disclosed is a novel method and system for efficiently synchronizing, transmitting, and receiving data between a base station and a plurality of customer premises. A MAC coprocessor (MCP) (402) is implemented, which works in conjunction with the MAC (410) in order to produce a robust, high throughput communication system. The MAC coprocessor (402) performs many of the tasks typically performed by prior art MAC's, including: during a downlink, storing a data frame, sorting the data frame according to modulation type or other criteria, determining when the data frame is full, and appending a set of CPE settings to the data frame. During an uplink, the MAC coprocessor (402) receives all data and routes the data either to the MAC (410) or a network backhaul. A MAC coprocessor (402) may be used in both the base station and Customer Premises. In both the downlink and uplink processes, having a MAC coprocessor working in conjunction with the MAC may significantly increase the communication system's throughput.
