Abstract: En un sistema de comunicaciones sin hilos en el que se transmiten múltiples flujos de datos a través de un canal compuesto, comprendiendo el canal compuesto una pluralidad de canales de transporte, un procedimiento caracterizado porque comprende: asignar un indicador de potencia a cada uno de la pluralidad de canales de transporte; aumentar el indicador de potencia de cada uno de la pluralidad de canales de transporte que tengan error de transmisión; disminuir el indicador de potencia de cada uno de la pluralidad de canales de transporte sin un error de transmisión; determinar un indicador de potencia máxima para el canal compuesto a partir de los indicadores de cada uno de la pluralidad de canales de transporte; y tomar una decisión de control de la potencia para el canal compuesto en base al indicador de potencia máxima.

Abstract: In a wireless communication system (10) having a composite transport channel made up of individual transport channels, a method for closed loop power control wherein multiple instances of the outer loop are performed in parallel. The method determines a Signal-to-Interference Ratio (SIR) threshold for the composite channel based on a channel quality metric evaluated for each of the individual channels. In one embodiment the channel quality metric is a Cyclical Redundancy Check (CRC) outcome.

Abstract: A method and apparatus for using information about a mobile terminal's location relative to a base station can improve performance of a communication system. In addition, information about the mobile terminal's velocity relative to the base station may be used to improve performance of the communication system. The location information may be used to estimate a nominal PN offset, and a set of PN offset to use, for processing communication signals. The velocity information may be used to estimate a nominal frequency of the communication signals.

Abstract: Techniques to efficiently generate memory addresses for a Turbo code interleaver using a number of look-up tables. An interleaver includes a storage unit, sets of tables, and an address generator. The storage unit stores K elements for a data packet at locations representative of an RxC array, with the elements being stored in a first (e.g., linear) order and provided in a second (e.g., interleaved) order. A first set of table(s) stores sequences (e.g., inter-row permutation sequences PA, PB, PC, and PD) used to perform row permutation of the array to map from the first order to the second order. A second set of table(s) stores sequences (e.g., intra-row base sequences and prime number sequences) used to perform column permutation. The address generator receives a first address for the first order and generates a corresponding second address for the second order based on sequences stored in the tables.

Abstract: A channel estimation method comprises determining that every longest-spreading-factor code having a common parent code with an all-ones pilot code is unoccupied. Channel estimation is performed using the common parent code during two or more time periods within a time period of the all-ones pilot code.

Abstract: Multiple access interference may be substantially removed by introducing a near-far situation in which a near mobile and a far mobile ("near" and "far" based on signal strength) are selected, resources allocated among these and other mobiles, and the data is packetized for transmission during a transmission interval such that the data intended for the far mobile is transmitted along with the data intended for the near mobile. Forward link signals are then appropriately scheduled. Signals intended for the far mobile and the near mobile are decoded from the composite signal received at the near mobile. The signal intended for the far mobile is then removed from the composite signal received at the near mobile.
