摘要： Se proporciona un método y sistema para adquisición de red inicial para un primer dispositivo que es asistido por un segundo dispositivo. En lugar de explorar una o más bandas de frecuencia para descubrir la información de red inalámbrica local, el primer dispositivo puede enviar una solicitud de información de red inalámbrica local sobre una interfaz de comunicación secundaria (es decir, una interfaz de comunicación no asociada con la red inalámbrica para la cual se busca la información). Un segundo dispositivo que puede haber obtenido previamente la información de red solicitada (por ejemplo, puede haberse unido o comunicado a través de la red inalámbrica) puede responder al enviar la información de red inalámbrica solicitada al primer dispositivo. Al recibir la información de red inalámbrica mediante su interfaz de comunicación secundaria, el primer dispositivo puede utilizarla para adquirir un servicio de comunicación de la red inalámbrica sobre una interfaz de comunicación primaria (es decir, diferente a la interfaz de comunicación secundaria).

摘要： A method and apparatus for conducting a pilot signal search in a wireless communications network. The location of a mobile is determined within the network. This location is then used in determining search window sizes and other search parameter information that is used to search all pilot signals identified in a designated pilot signal set. Search window size is also determined based upon the location of the mobile and another component related to multipath effects for a transmitted pilot signal.

摘要： A method and apparatus for detecting forward and reverse link imbalances in a digital cellular communication system. The method preferably uses an indication of "maximum access probes" (104) to determine whether a link imbalance caused a reverse link failure to occur. The maximum access probes condition indicates that a wireless unit has attempted to access a base station a pre-defined maximum number of times. The method preferably uses an, indication of a lost paging channel (132) and a traffic channel initialization (TCI) time out (160) to determine whether a link imbalance caused a forward link failure to occur. If the wireless unit did not lose the paging channel (132), the method determines whether a TCI time out occurred (160). If the wireless unit lost the paging channel, or it did not lose the paging channel but a TCI time out occurred, the method determines the cause for the forward link failure. There are two potential causes in this scenario: (1) either the wireless unit is a significant distance from the base station; or (2) the paging channel suffers from significant interference. The method determines the cause and either instructs the wireless unit to perform an idle handoff to a neighboring base station or to exit the digital system.

摘要： A system and method for determining a position of a mobile wireless transceiver. A Doppler shift of signals transmitted from first and second satellites, respectively, relative to a base station is calculated. A first set of pseudo ranges of the first and second satellites, respectively, relative to the base station is also calculated. Satellite identification information, Doppler shift information, and the pseudo range information between the base station and the wireless transceiver is sent to wireless transceiver. The wireless transceiver use the information received from the base station to identify a second set of pseudo ranges between the wireless transceiver and the first and second satellites, respectively, at a time tx. The wireless transceiver sends the second set of pseudo ranges between the wireless transceiver and the first and second satellites, respectively, along with time information tx to the base station, in response to which, the base station calculate the position of the wireless transceiver.

摘要： A system and method for monitoring the load on a CDMA communication system having a base station and a plurality of users. A measure of voice activity in the communication system is determined, and a current value of frequency reuse efficiency equal to an initial value of frequency reuse efficiency is provided. A power determination is made according to the measured voice activity and the current value of frequency reuse efficiency. The current value of frequency reuse efficiency is updated using the power determination to provide a new current value of frequency reuse efficiency. The power determination and the update of the frequency reuse efficiency are iteratively repeated until convergence to provide a converged value of frequency reuse efficiency. The load on the communication system is then determined according to the converged frequency reuse efficiency value.

摘要： Techniques for extending coverage of a wireless communication network (e. g., a cellular network) to indoor and other locations are described. A wirel ess device may communicate with a base station in a wireless network via dow nlink and uplink frequency channels in a licensed frequency band using frequ ency division duplexing (FDD). The wireless device may communicate with a pi conet base station (PBS) in a pico network (piconet) via the uplink frequenc y channel using time division duplexing (TDD). The PBS may communicate with the wireless device on the uplink frequency channel and may exchange data wi th the wireless network via a wireline communication link. The PBS may forwa rd data received from the wireless device to the wireless network and may al so forward data received from the wireless network for the wireless device t o the wireless device. The PBS may receive paging messages from the wireless network for the wireless device and may forward the paging messages to the wireless device.
