Abstract: A method and apparatus for controlling a rate of path searching for a channel in a communication system include searching for new path delays and identifying a number of new path delays during a specific time period. The identified number of new path delays are compared to at least one threshold value. The result of the comparison is used to alter the rate of path searching.

Abstract: Un aparato para controlar retardos de los dedos RAKE (del rastrillo), que comprende: un buscador (402) de caminos configurado para buscar un canal de radio para las posiciones de los componentes de caminos múltiples y para proporcionar una estimación de baja resolución de las posiciones de componentes de caminos múltiples; una etapa (404) de sintonización de caminos configurada para buscar el canal, basándose en la estimación de baja resolución de las posiciones de los componentes de caminos múltiples, y para proporcionar una estimación de alta resolución de la posición del componente de caminos múltiples; una etapa (406) de seguimiento de caminos, configurada para hacer un seguimiento de las posiciones existentes de los componentes de caminos múltiples proporcionadas por la etapa (404) de sintonización de caminos, de una manera tal que las posiciones de componentes de caminos múltiples existentes son conocidas incluso después de haber cambiado; y una etapa (408) de selección de caminos, configurada para combinar las posiciones existentes de componentes de caminos múltiples de los que se hace un seguimiento, suministradas por la etapa (406) de seguimiento de caminos con nuevas posiciones de componentes de caminos múltiples proporcionadas por la etapa (404) de sintonización de caminos, incluyendo la selección de uno o más componentes de caminos múltiples entre las posiciones existentes de componentes de caminos múltiples y las nuevas posiciones de componentes de caminos múltiples, basándose en al menos unos criterios predeterminados, caracterizado porque la etapa (408) de selección de caminos está configurada además para mantener una separación mínima entre el uno o más componentes de caminos múltiples seleccionados.

Abstract: Method and system are disclosed for providing advanced RAKE delay control in wireless communications systems. The RAKE delay control method and system of the invention is capable of tracking presently known paths over time and merging the tracking results with new path searcher results. The invention is particularly suitable for devices where the resources (e.g., computational load, power) available for detecting the multipath components are limited. The result is a resource efficient architecture for positioning the RAKE fingers to best extract the signal power available in the channel and to utilize the inherent diversity due to the multipath nature of the signal.
