    Abstract: A method and apparatus for controlling transmit power levels of a plurality of different data streams (120, 120a, 122, 122a, 124, 124a) transmitted from at least one base station to a mobile station in a mobile radio communication system. The first and second data streams are trasmitted from the base station and received at the mobile station. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station. A received stream of power control commands is formed from the received power control signal at the base station, and the transmit power levels of the first and second data streams from the base station are controlled in accordance with the received stream of power control commands.

    Abstract: Methods and apparatus are presented for dynamically controlling the re-transmission scheme of acknowledgment signals. A source transmits a first data packet over a slot s1. If channel conditions are favorable, source transmits a second data packet over slot s2, which precedes the reception of any acknowledgment signals. A destination receives first data packet over slot d1 and second data packet over slot d2. Destination decodes first data packet during slots d2 and d3, and second data packet over slots d3 and d4. Destination transmits an acknowledgment signal (ACK1) associated with first data packet during slot d4. Rather then transmitting the second ACK1 associated with first data packet over slot d5, destination preempts this slot with an acknowledgment signal ACK2, which is associated with second data packet transmitted by source. Hence, destination is configured to overwrite the repetition of a previous acknowledgment in order to transmit a new acknowledgment.

    Abstract: A method and apparatus for determining a position of a mobile satellite positioning system (SPS) receiver is described. A position of a mobile satellite positioning system (SPS) receiver is determined by initially determining a plurality of satellite pseudoranges between said mobile SPS receiver and a corresponding plurality of satellites. Then, at least one non-satellite pseudomeasurement is determined. Finally, a condition of at least one of said plurality of satellite pseudoranges is determined.

    Abstract: A method and apparatus for providing orthogonal spot beams (14a, 14b), sectors (16a, 16b), and picocells (18). The transmissions can be made orthogonal by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. In accordance with the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero. The 64-chip all zeros Walsh sequence can be designated as P and the 64-chip all one sequence can be designated as M. In the present invention, additional pilot signals can be provided by concatenating 64-chip all zeros P and all ones M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM, PPMM, and PMMP can be used. The present invention can be extended such that any required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence depending on the value of that bit.

    Abstract: Un método para comunicaciones inalámbricas donde un paquete de control no se transmite para todas las transmisiones de un nuevo paquete de datos. Un paquete de datos se envía únicamente con una retransmisión de un paquete de datos donde el paquete de datos transmitido anteriormente no es recibido completamente. El paquete de control contiene información relacionada con un paquete de datos transmitido anteriormente. El paquete de datos transmitido anteriormente y el paquete de datos de retransmisión se derivan de los datos comunes. Los datos comunes se derivan con base en la información relacionada con el paquete de datos transmitido anteriormente, donde el paquete de datos transmitido anteriormente y el paquete de datos de retransmisión se encuentran asociados con una serie de paquetes de datos.

    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.

    Abstract: In a high data rate communication system, a method and apparatus for selectively reducing the power of signals transmitted by an access terminal. The access terminal generates an access metric based on throughput or data rate control (DRC) information. The access terminal then compares the access metric to an access metric threshold and gates or reduces its transmit power based on the results of the comparison. The access terminal uses algorithms to determine the access metric and access metric threshold that reduce transmit power during periods when the access terminal would not be selected to receive data from an access network according to an access network selection algorithm.
