Abstract

L'invention concerne un procédé pour répartir une voie en liaison montante d'une station mobile (MS) qui est en transfert souple dans un système de communications mobile. De manière spécifique, la station mobile reçoit une pluralité de commandes de répartition d'une cellule inactive et détermine si une condition spécifiée est satisfaite à partir des commandes de répartition reçues. Puis, la station mobile ajuste la puissance de transmission maximale, lorsque la condition spécifiée est remplie.
