    Abstract: Un procedimiento de control centralizado de la potencia transmitida en un sistema de comunicación que incluye un conjunto de estaciones de base (14, 16, 18, 20) en comunicación con una unidad remota (10), que comprende las etapas de: recibir en cada estación de base del conjunto de estaciones de base (14, 16, 18, 20) una trama del enlace inverso de los datos de la unidad remota (10); determinar en cada estación de base del conjunto de estaciones de base (14, 16, 18, 20) una indicación de calidad de la trama correspondiente a la trama de datos del enlace inverso recibido; transmitir desde cada estación de base del conjunto de estaciones de base (14, 16, 18, 20) la indicación de calidad de la trama a un controlador del sistema (22, 24); calcular por el controlador del sistema (22, 24), sobre la base de la indicación de calidad de la trama de cada estación de base del conjunto de estaciones de base (14, 16, 18, 20), una indicación de la calidad de la trama agregada correspondiente a la trama de datos del enlace inverso recibida; calcular un valor de umbral inverso absoluto sobre la base de la indicación de calidad de la trama agregada; proporcionar el valor de umbral inverso absoluto a cada estación de base del conjunto de estaciones de base (14, 16, 18, 20), y proporcionar un comando de control de potencia a la unidad remota de cada estación de base del conjunto de estaciones de base (14, 16, 18, 20) sobre la base de una comparación entre la indicación de la calidad de trama determinada en la estación de base y el valor de umbral inverso absoluto.

    Abstract: Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at R-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

    Abstract: In the present invention, the slave base station attains synchronization with the reference base station through messages transmitted from and received by a mobile station either in the soft handoff region between the reference base station and the slave base station or within a range which allows the mobile station to communicate with the slave base station. When the mobile station is not in communication with both the reference base station and the slave base station, then the round trip delay between the mobile station and the reference base station is measured by the reference base station. The reference base station communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station acquires the signal from the mobile station and determines when the signal from the mobile station arrives. The slave base station then makes an estimate as to the length of the delay between transmission of a signal from the mobile station to the slave base station. Based upon these measurements and estimates, the slave base station determines the error which is present in the slave base station system time.

    Abstract: A wireless telecommunications system that includes a base station, a plurality of remote stations, a first channel for general page messages containing paging information and broadcast databurst message references, and an auxiliary channel for broadcast databurst notification indicators for the purpose of increasing standby time in remote stations configured to receive broadcast databurs messages. The auxiliary channel in one embodiment is an uncoded, on-off keying (OOK) modulated direct sequence spread spectrum signal. In another embodiment the broadcast databurst notification indicators are one or more indicator bits set on the auxiliary channel to indicate to a remote station whether it needs to examine the first channel for broadcast databurst message references. In another embodiment, broadcast databurst notification indicators are multiplexed onto a quick paging channel along with incoming page notification indicators. In another exemplary embodiment a new channel is used for transmission of the broadcast databurst notification indicators.

    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: An outer encoder and an inner encoder encode subsets of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. The use of a combiner at an outer decoder enables better outer decoding of symbols.
