Abstract: Un procedimiento de monitorización de la calidad de la información recibida sobre un canal de comunicación inalámbrica, que comprende: crear un vector de referencia de canal piloto sumando de manera coherente elementos de código de canal piloto; crear un vector de bit artificial extrayendo un segmento del vector de referencia de canal piloto; proyectar el vector de bit artificial sobre el vector de referencia de canal piloto; determinar una polaridad del bit artificial; calcular una tasa de error de bits proxy a partir de la polaridad del bit artificial; y usar la tasa de error de bits proxy para monitorizar una calidad de la información recibida.

Abstract: Un procedimiento para combinar de forma selectiva una pluralidad de transmisiones recibidas a partir de una pluralidad de fuentes de señal respectivas para recuperar un mensaje compuesto por una pluralidad de tramas, caracterizado el procedimiento por las etapas de: procesar cada una de la pluralidad de transmisiones recibidas a partir de la pluralidad de fuentes de señal respectivas por separado para recuperar el mensaje; y si el mensaje no puede recuperarse sin errores a partir de una única transmisión recibida, determinar tramas borradas en un mensaje recuperado de una primera transmisión recibida, determinar tramas buenas recuperadas a partir de unas restantes de la pluralidad de transmisiones recibidas, formar al menos un mensaje combinado, en el que cada mensaje combinado incluye una combinación particular de tramas buenas que sustituyen a las tramas borradas, y comprobar cada mensaje combinado para determinar si es bueno o está borrado.

Abstract: In wireless communications, it is necessary to monitor the transmission quality of communications channels to maintain system performance and operation. The invention provides a way of measuring bit error rates in channels at the receiver, without diminishing channel throughput by inserting quality monitoring data into the signal at the transmitter.

Abstract: A power control system for use in facilitating transition to an active state. The system includes a first transceiver (104), such as a BTS, having the ability to initiate transmission of a power control function. The transceiver (104) comprises a generator (210) and a transmitter (202) for the power control arrangement. The system further includes a second transceiver (106), such as a terminal, for receiving the power control arrangement and coherently combining the power control arrangement to determine a state transition indication. The second transceiver (106) includes a transmitter (204) that transmits a selected waveform subsequent to the coherent combining. The first transceiver (104) receives the selected waveform, determines a power level associated therewith, and provides feedback to the second transceiver (106). The power control arrangement may include groups of redundant power control data, data transmitted on idle feedback dimensions, or predetermined signal patterns in addition to at least one power control group.

Abstract: A method and apparatus for reducing transmission delay in a wireless communication system that carries packetized voice and data information. Interruptions in the traffic channels cause loss of synchronization between a header compressor and a header decompressor. Rather than transmitting resyinchronization information on the traffic channel, the information dropped by an interruption is re-transmitted on a non-traffic channel in parallel with the traffic channel. At the remote station, information from the traffic channel and the non-traffic channel is reassembled before input into the decompressor. Alternatively, the non-traffic channel can be used to carry overflow information so that a higher average data rate can be achieved than the average data rate of the traffic channel alone.

Abstract: Techniques to adjust the setpoint of a power control loop in a wireless communication system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics include one of a re-encoded power metric and a modified Yamamoto metric. The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.

Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques involve transmitting a signal over a plurality of time periods, receiving a plurality of parameters each relating to the signal transmission during a different one of the time periods, filtering a first one of the parameters to generate a first filtered parameter, filtering a second one of the parameters as a function of the first filtered parameter to generate a second filtered parameter, and adjusting the signal as a function of the second filtered parameter.
