Abstract: A data channel for transmitting data from a base station to subscriber stations is provided. Each subscriber station has a different service-class which reflects the reception-quality of the data transmitted from the base station. The data channel is organized into a plurality of frames. Each frame contains service-class information that is packaged in the frame in such a manner that all subscriber stations can recover the service-class information. The frame also includes payload data destined for at least one of the subscriber stations. The payload data is packaged in the frame in such a manner that the subscriber station having payload data destined therefore can recover its payload data, regardless of its service class. Subscriber stations that have no payload data destined therefore, and/or which are in a poorer service-class than the destined subscriber-stations, can use the service-class information to determine that the remainder of the frame can be ignored. An apparatus, system and method relating to the data channel are also provided.

Abstract: Un metodo, sistema y aparato para determinar un formato de bloque a utilizarse para transmitir un bloque de datos sobre un canal hacia un receptor al colectar una seria de medidas de recepcion-calidad, determinar la velocidad de cambio de la recepcion-calidad, o la velocidad a la cual se estan haciendo las solicitudes de transmision, y, dependiendo de la magnitud de la velocidad de cambio o la velocidad de solicitudes de retransmision, ya sea: promediar la parte mas baja de las medidas de recepcion-calidad durante el tiempo-serie y determinar el formato de bloque en base al promedio; o determinar el formato de bloque basado en las medidas de recepcion-calidad mas recientes.

Abstract: A system and method of determining the maximum uplink transmit power of a subscriber station from a remote base station where the subscriber station reports incidents of foldback in its radio to the base station. When the base station receives the report, it reduces the maximum uplink transmit power of the subscriber station. After a period of time lapses without any reports of foldback occurring, the base station increases the maximum uplink transmit power of the subscriber station.

Abstract: Se describen un aparato, un sistema y un metodo para mejorar la SNR de una senal deseada recibida en un receptor en un sistema de comunicacion de acceso multiple. El aparato, sistema y metodo substraen senales conocidas o que se pueden conocer de la senal total recibida en el receptor y la senal deseada despues es determinada a partir del resultado de la substraccion. Las senales conocidas, o que se pueden conocer, pueden ser senales de sincronizacion u otras senales de canal de interferencia transmitidas por el transmisor, tal como una estacion de base de red inalambrica, sirviendo al receptor, tal como una estacion de suscriptor en dicha red inalambrica, y/o pueden ser senales transmitidas por otro transmisor, tal como una estacion de base adyacente, o un sector adyacente en sistemas de sectores multiples.

Abstract: A novel communication channel structure and method in a wireless communicati on system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and th e subscriber stations are given access to a variety of channels, including at least one uplink data channel. The uplink data channel can operate in at lea st a random access mode and a polled access mode. The base station informs each subscriber station it serves of the current mode of the uplink channel via a n associated downlink signaling channel and, in random access mode, each subscriber station is able to randomly access the shared uplink channel. In polled mode, each subscriber station waits for permission from the base station before sending data over the shared uplink channel. A method of operating the system monitors the collisions which occur on the uplink chann el in random mode and/or the amount of data and/or the data's priority level and/or QoS requirements and switches the system between random and polled modes as appropriate. In polled mode, the method determines which subscriber stations should access the uplink and when.

Abstract: The present invention provides a novel system, method and apparatus for allocating power between at least two communication services that share a common power output limit. Two communication services particularly suited for the present invention are voice services and data services transmitted on the downlink of a wireless network. An embodiment of the method includes determining the actual consumption of power on the voice channels of the wireless network during a given time period, and allocating substantially the same amount of power to the voice channels for the next time period, thus allowing for the allocation of the remaining amount of power to the data services, and thereby allowing, for example, increased modulation of the data services and thereby improve overall rates of data transfer and/or reliability of data transmission. Another embodiment of the method includes determining the power requirements for at least one communication service during the current time period; and, allocating a portion of the power budget to each communication services based on the determination.

Abstract: A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capacity and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a channel having located transmission capacity dedicated to the communication while connectionless communications can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The allocation of transmission capacity between the dedicated channels and the shared channel can be fixed, or can be managed to meet network or network operator requirements. The structure and method can also be managed by the network operator to permit prioritization of some communciations over others. In another embodiment, two or more shared channels are provided in addition to the dedicated channels.
