Patent

CA 2380994

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.

L'invention concerne un procédé et un dispositif servant à commander une recherche de signal pilote dans un réseau de communications sans fil. L'emplacement d'un mobile est déterminé dans le réseau. Cet emplacement est ensuite utilisé pour déterminer des tailles de fenêtre de recherche et d'autres informations de paramètres de recherche, utilisées pour rechercher tous les signaux pilotes identifiés dans un ensemble de signaux pilotes désigné. La taille de la fenêtre de recherche est également déterminée sur la base de l'emplacement du mobile et d'une autre composante liée aux effets de propagation par trajet multiple d'un signal pilote transmis.
