CA 2150542

A method and apparatus providing softer handoff of a mobile unit (90) between sectors (50, 70 and 80) of a common base station (60). A sectorized base station (60) comprises a set of demodulation elements (240A-204N). Each demodulation element (240A-204N) may be assigned to a signal from one of a plurality of sectors. The output of the demodulators (240A-204N) are combined before the decoding process independent of the sector from which the data originated. This configuration provides improved output data reliability, more stable power control, and more efficient use of resources at the base station.

Procédé et appareil permettant un transfert plus doux d'une unité mobile (90) entre des secteurs (50, 70 et 80) d'une station de base commune (60). Une station de base (60) divisée en secteurs comporte un ensemble d'éléments démodulateurs (240A-204N). Chaque élément démodulateur (240A-204N) peut être affecté à un signal provenant d'un ou plusieurs secteurs. Les signaux de sortie des démodulateurs (240A-204N) sont combinés avant l'opération de décodage, indépendamment du secteur duquel les données proviennent. Cette configuration améliore la fiabilité des données de sortie, un contrôle plus stable de la puissance et une utilisation plus rationnelle des ressources par la station de base.
