Abstract: A spread spectrum receiver subsystem for utilization in a CDMA cellular telephone having a searcher receiver for scanning the time domain so as to use the PN processing gain and time discrimination properties of spread spectrum coding to determine the location in the time domain and the received signal strength of multiple receptions of a pilot signal traveling upon one or more physical propagation paths to reception. The searcher receiver provides a control signal indicative of the received pilot signals of greatest strength and corresponding time relationship. A data receiver receives spread spectrum communication signals accompanying each received pilot signal and is responsive to the searcher control signal for acquiring and demodulating a spread spectrum communication signal, concomitant with the pilot signal of greatest signal strength, and thus providing a corresponding information bearing encoded output signal.

Abstract: An apparatus and method for identifying remote communications transmitted via a repeater from remote communications not transmitted via the repeater. The method comprises the steps of receiving a plurality of signal transmissions originating from a plurality of remote stations, wherein each of the signal transmissions is associated with a call originating from one of the plurality of remote stations; processing the plurality of received signal transmissions to identify received transmissions that include a discriminant applied by a repeater; and designating each of the plurality of received signal transmissions as being transmitted via the repeater if the received signal transmission includes the discriminant.

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 novel method and apparatus for providing both voice services and data services in a High Data Rate (HDR) wireless communication system. At least one sub-channel is formed on the forward link of the HDR system. The at least one sub-channel comprise at least one time slot that occupies a specified position in a frame of the forward link. The at least one sub-channel is assigned for voice services. The voice services at the at least one sub-channel are provided in accordance with a CDMA principles. Such principles are disclosed e.g., in IS-95, cdma2000, or other standards known to one skilled in the art. The remaining time slots are used for data services. In another aspect of the invention, additional sub-channels are formed, utilizing all remaining time slots. The additional sub-channels are assigned to data services, such that each sub-channel carries data to a different user. The number of sub-channels assigned to voice services, and the number of sub-channels assigned to voice services changes with varying needs for voice services and data services.

Abstract: A distributed antenna system is utilized in a system for providing multipath signals which facilitate signal diversity for enhanced system performance. Each node of the antenna comprises more than one antenna. Each antenna at a common node provides a path having a different delay to the base station.

Abstract: Un procedimiento (1000) para procesar señales de comunicación en un trayecto de retorno de un satélite (300), el procedimiento que comprende: recibir (1002), a través de una antena (361) acoplada al trayecto de retorno, un número de señales de datos en un canal de frecuencia única (701-708), en el que cada una del número de señales de datos ocupa un sub-canal de tiempo-frecuencia única (701A-701E) del canal de frecuencia única (701-708), se origina en uno correspondiente de un número de terminales de usuario, UT, (400, 401) e incluye una pluralidad de ranuras temporales asignadas de forma dinámica a un grupo de dispositivos de equipo de usuario, UE, (500, 501) asociados al UT correspondiente (400, 401), caracterizado por: determinar (1004) un nivel de potencia combinado de todo el número de señales de datos recibidas que ocupan todos los sub-canales de tiempo-frecuencia (701A-701E) del canal de frecuencia única (701- 708); y ajustar (1006) una ganancia del amplificador aplicada al número de señales de datos recibidas en el trayecto de retorno basándose, al menos en parte, en el nivel de potencia combinado.

Abstract: In a cellular telephone system a system for directing communications between a mobile user and cell-sites as a mobile user changes cell-site service areas. The mobile user includes an apparatus for, while in communication with another system user via one cell-site, determining a transition of the mobile user from the cell-site service area to the service area of another cell-site. The system includes circuitry responsive to the indication for coupling communications between the mobile user and the other system user via the new cell-site while the mobile user also remains in communication with the system user via the first cell-site. The system further includes apparatus responsive to the coupling of the communications between the mobile user and the other system user via the new cell-site for terminating the communications between the mobile user and another system user via cell-site with communications continuing between the mobile user and the system user via the new cell-site.
