Patent

CA 2304133

A channel communication apparatus and method are provided for a CDMA communication system method for acquiring signals from multiple adjacent base stations by a terminal; for providing more efficient set management; for providing more efficient multipath acquisition and finger assignment; and for acquiring a signal sent from an adjacent base station and a multipath signal which can reduce power consumption and hardware complexity in the terminal. The apparatus and methods also accurately measure the power or time delay of a signal received from a base station by a terminal in a CDMA communication system.

L'invention concerne un procédé et un appareil de communications en mode canal, dans un système de communications à accès multiple par répartition de code (CDMA), permettant à un terminal d'acquérir des signaux provenant de plusieurs stations de base adjacentes. Ce procédé permet une gestion d'ensemble plus efficace; l'acquisition des trajets multiples et l'affectation de doigts plus efficaces; l'acquisition d'un signal envoyé par une station de base adjacente et d'un signal à trajets multiples pouvant réduire la consommation d'énergie et la complexité du matériel dans le terminal. L'appareil et le procédé permettent de mesurer, de manière précise, la puissance ou le retard d'un signal reçu par un terminal à partir d'une station de base dans système de communications CDMA.
