Abstract: Un sistema y un metodo para determinar la maxima energia de transmision ascendente de una estacion del suscriptor desde una estacion de base remota, en donde la estacion del suscriptor reporta incidentes de la regresion en su radio hacia la estacion de base. Cuando la estacion de base recibe el reporte, reduce la energia maxima de transmision ascendente de la estacion del suscriptor. Despues de que transcurre un periodo de tiempo sin ningun reporte de un evento de regresion, la estacion de base aumenta la energia maxima de transmision ascendente de la estacion del suscriptor.

Abstract: Un canal de control para un sistema de linea de suscriptor digital inalambrica y similar, u otros sistemas de comunicaciones que puedan beneficiarse de un canal de control que proporcione una conexion de baja velocidad de datos entre las estaciones sobre una base continua, hace un uso eficiente de la capacidad de transmision en los sistemas de comunicaciones. En una modalidad, el canal de control tiene una estructura que emplea marcos ranurados, a un usuario se le pueden asignar multiples ranuras, una sola ranura, o menos de una sola ranura (ranuras compartidas con otros usuarios) para satisfacer las necesidades de transmision de datos del usuario. Tambien, se pueden designar una o mas ranuras como ranuras de acceso aleatorio a las que los usuarios pueden tener acceso por medio de un protocolo de acceso aleatorio tipo Aloha u otro, segun sea necesario.

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.

Abstract: A method, system and apparatus for determining a block format to be used to transmit a block of data over a channel to a receiver by collecting a series of reception-quality measurements, determining the rate of change of the reception-quality or the rate at which retransmission requests are being made, and, depending upon the magnitude of the rate of change or the rate of retransmission requests, either: averaging the lowest portion of the reception-quality measurements during the time-series and determining the block format based upon the average; or determining the block format based upon the most recent reception-quality measurements.

Abstract: An apparatus, system and method for improving the SNR of a desired signal received at a receiver in a multiple access communication system is disclosed. The apparatus, system and method subtracts known or knowable signals from the total signal received at the receiver and the desired signal is then determined from the result of the subtraction. The known, or knowable, signals can be synchronization signals or other interfering channel signals transmitted by the transmitter, such as a wireless network base station, serving the receiver, such as a subscriber station in such a wireless network, and/or can be such signals transmitted by another transmitter, such as an adjacent base station, or an adjacent sector in multi-sector systems.

Abstract: A data channel to transmit data from a transmitter to one or more of a plurality of receivers, each of which intermittently reports to the transmitter its reception quality of signals transmitted by the transmitter. The transmitter transmits the data in frames which include at least one block. Each block includes the same predefined number of traffic symbols, and includes a header portion and a payload portion. The header portion of each block is packaged for transmission in a robust manner, enhancing the probability that each receiver will be able to recover it and the header portion includes information required to recover the payload portion. The payload portion is, in accordance with the reception quality reported by the intended receiver, packaged to make efficient use of the transmission resources while ensuring a reasonable probability that the intended receiver will be able to recover the payload. The header portion can include indications of the modulation, forward error correction and repetition utilized to package the payload and can indicate the length of the payload.

Abstract: Se proporciona una estructura y metodo de comunicacion que permite que se proporcionen comunicaciones con vinculos parecidos a conexiones y sin conexiones en un enlace multiplexado. La estructura y metodo puede hacer uso eficiente de la capacidad de transmision disponible y/o de los recursos de la red, mientras proporciona ambos tipos de comunicacion. Las comunicaciones con vinculos parecidos a conexiones se pueden proporcionar mediante un canal que tenga amplitud de banda asignada dedicada a la comunicacion, mientras que la comunicacion sin conexiones se puede proporcionar mediante un canal compartido a traves del cual se puedan transmitir datos a los suscriptores. En una modalidad, el canal compartido transmite cuadros de paquetes dirigidos a uno o mas de los suscriptores. Los cuadros pueden tener un encabezamiento robustamente empaquetado que pueden recibir todas las estaciones suscriptoras a las que de servicio la estacion base, mientras que los datos de carga util en el cuadro se pueden empaquetar con un nivel de robustez apropiado para la estacion suscriptora pretendida. Los diferentes empaquetamientos pueden incluir diferente codificacion y/o modulacion de los datos de carga util. La asignacion de la amplitud de banda entre los canales dedicados y el canal de difusion puede ser fija, o se puede administrar para satisfacer los requerimientos de la red o del operador de la red. El operador de la red tambien puede administrar la estructura y metodo para permitir la prioritizacion de algunas comunicaciones sobre otras. En otra modalidad se proporcionan dos o mas canales compartidos. En otra modalidad, se pueden crear canales dedicados con diferentes cantidades de amplitud de banda y/o pueden emplear modulacion y/o codificacion seleccionadas de conformidad con la calidad de recepcion de la estacion suscriptora receptora.

Abstract: A novel communication channel structure and method in a wireless communication system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and the 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 least 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 an 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 channel 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: A method and system for selecting and reselecting an antenna direction for an antenna capable of transmitting signals in one of at least two selectable directions. The average received signal-to-interference ratio is used to initially select the antenna direction. Thereafter the average received signal-to-interference ratio is monitored and the antenna direction reselected when the average received signal-to-interference ratio rises too far below the average received signal-to-interference ratio used to initially select the antenna direction for too long too often and if the antenna is not then required for a transmission that cannot be interrupted. If the average received signal-to-interference ratio drops significantly below the level used to initially select the antenna direction, then that level is reset downward. Reselection, if commenced, is repeated periodically until the antenna is required for transmission of a signal.
